Quick answer
A $100,000 immediate annuity pays roughly $500 to $600 a month for a 65-year-old today, while $500,000 generates about $2,500 to $3,000 a month. Your actual payout depends on your age, the annuity type, current interest rates, and whether you want income for life or for a set term.
How much monthly income will your annuity pay? A $100,000 immediate annuity pays roughly $500–$600 per month for a 65-year-old today, while $500,000 generates approximately $2,500–$3,000 per month — but your actual payout depends on your age, the annuity type, current interest rates, and whether you want income for life or a set term.

What Is an Annuity Calculator and How Does It Work?
An annuity calculator is a tool that translates your premium, interest rate, and payout preferences into a concrete monthly or annual income estimate. Think of it as a financial what-if machine: you plug in your numbers, and it shows you what kind of check you could expect — whether that’s for 10 years, 30 years, or the rest of your life.
Key inputs: premium, interest rate, term, and payout type
Every annuity calculator asks for roughly the same four things:
- Premium — the lump sum (or series of payments) you’re putting in
- Interest rate — the guaranteed rate the carrier credits, or an assumed growth rate
- Term — how long payouts last (fixed period vs. lifetime)
- Payout type — immediate vs. deferred, single-life vs. joint-life, with or without a cost-of-living adjustment (COLA)
Change any one of these and your monthly number shifts — sometimes dramatically.
How the annuity calculation formula turns inputs into estimates
A simple fixed-period annuity uses a present-value formula: your premium is divided into equal payments over the term, with each payment adjusted for the interest rate the money is still earning inside the contract. Lifetime annuities layer in actuarial life expectancy tables, which is why a 55-year-old and a 75-year-old get very different monthly checks on the same $200,000.
Why results vary across free annuity calculators
Free online calculators use generic assumptions — an average rate environment, average life expectancy, no riders. A real carrier quote factors in your exact age, gender, state of residence, and any optional benefits you add (like a death benefit or income rider). That’s why two calculators can spit out numbers that differ by $100 or more per month on the same premium. Use free tools to ballpark your options; get live carrier quotes to confirm.
What is the biggest disadvantage of an annuity? Liquidity. Once you hand over your premium, most of that money is locked up. Surrender charges can run 7–10% in the early years, and even after the surrender period ends, you generally can’t access the full principal without penalty. If you need flexibility, an annuity may not be the right fit for that portion of your savings.
Monthly Annuity Calculator: Estimate Your Monthly Income
The numbers below assume a 65-year-old purchasing a single-premium immediate annuity (SPIA) with a single-life payout and no COLA, in a mid-range interest rate environment. Ranges reflect the spread between lower-rate and higher-rate carrier quotes available today. Your actual quote will vary — if you’re shopping for annuity coverage, comparing personalized rates from top carriers is the fastest way to narrow that range.
How much does a $100,000 annuity pay per month?
A $100,000 SPIA typically pays $500–$600 per month for a 65-year-old. Add a joint-life option (covering a spouse) and that drops to roughly $430–$520/month because the carrier is insuring two lives.
How much will a $250,000 annuity pay per month?
Scale the same logic up and a $250,000 immediate annuity pays approximately $1,250–$1,500 per month for a single-life payout at 65. A 10-year period-certain guarantee (so your heirs receive payments if you die early) shaves that down to around $1,175–$1,400/month.
How much does a $400,000 annuity pay per month?
A $400,000 premium at age 65 generates roughly $2,000–$2,400 per month on a single-life immediate annuity. At 70, the same premium jumps closer to $2,400–$2,800/month because you’re statistically expected to collect for fewer years.
How much does a $600,000 annuity pay per month?
A $600,000 SPIA typically pays $3,000–$3,600 per month for a 65-year-old with a single-life contract. Joint-life coverage for a same-age spouse would bring that to approximately $2,600–$3,100/month.
How much will a $1,000,000 annuity pay monthly?
A $1,000,000 immediate annuity pays approximately $5,000–$6,000 per month for a 65-year-old on a single-life basis. That works out to $60,000–$72,000 per year — a meaningful income stream for most retirement budgets.
| Premium | Est. Monthly Payout (Age 65, Single-Life SPIA) |
|---|---|
| $100,000 | $500–$600 |
| $250,000 | $1,250–$1,500 |
| $400,000 | $2,000–$2,400 |
| $600,000 | $3,000–$3,600 |
| $1,000,000 | $5,000–$6,000 |
Ranges reflect mid-rate-environment estimates. Actual quotes vary by carrier, state, and individual profile.
Immediate Annuity Calculator: Turn a Lump Sum Into Instant Income
An immediate annuity starts paying within 30 days of your premium — sometimes the very next month. It’s the simplest kind to calculate because there’s no accumulation phase.
How an immediate annuity calculator differs from a deferred calculator
A deferred annuity calculator has two phases: accumulation (your money grows) and distribution (you receive payments). An immediate annuity calculator skips straight to the payout phase. The math is simpler, but the tradeoff is that you give up control of your principal right away.
Immediate annuity calculator with taxes: what to expect after Uncle Sam
When you fund an annuity with after-tax dollars (non-qualified money), the IRS splits each payment into a taxable portion and a tax-free return-of-principal portion. This is called the exclusion ratio. If you put in $100,000 and the carrier expects to pay out $180,000 over your lifetime, roughly 56% of each payment comes back tax-free. The rest is ordinary income. On a $600/month payment, you might only owe income tax on $265 of it.
Qualified annuities (funded with IRA or 401(k) money) are fully taxable as ordinary income because those contributions were pre-tax.
Immediate annuity calculator with COLA: inflation-adjusted payout estimates
Adding a cost-of-living adjustment — typically 1–3% annually — lowers your starting payout by 15–25% but protects purchasing power over time. On a $300,000 SPIA at 65, a 3% COLA option might start at $1,200/month instead of $1,500/month, then grow each year.
Immediate lifetime annuity calculator: income you can’t outlive
A lifetime immediate annuity keeps paying as long as you’re alive — even if you live to 100. The carrier assumes longevity risk. The tradeoff: if you die in year two, payments usually stop (unless you bought a period-certain guarantee).
How much would a $500,000 annuity pay annually? A $500,000 SPIA at 65 pays approximately $30,000–$36,000 per year ($2,500–$3,000/month) on a single-life basis. Adding a 10-year period-certain guarantee drops the annual figure to roughly $28,000–$33,000.
Fixed Annuity Calculator: Lock In a Guaranteed Rate
A fixed annuity — specifically a multi-year guaranteed annuity (MYGA) — works like a CD issued by an insurance company. You deposit a lump sum, it earns a fixed interest rate for a set term (typically 3–10 years), and then you decide what to do with it.
Fixed annuity calculator payout: how guaranteed interest compounds
Because the rate is fixed and the term is defined, a fixed annuity calculator is the most straightforward: principal × (1 + rate)^years. A $100,000 MYGA at 5% for 5 years grows to about $127,628 before any distributions. Many people roll that into an immediate or lifetime annuity at the end of the term.
Fixed annuity calculator with taxes: ordinary income vs. exclusion ratio
Fixed annuity gains are tax-deferred until withdrawal. When you take distributions, the growth portion is taxed as ordinary income — not at the capital gains rate. If you annuitize (convert to an income stream), the exclusion ratio applies and only the gain portion of each payment is taxable.
Best fixed annuity calculator options and what to compare
When comparing fixed annuity calculators, look for tools that let you toggle:
- The guaranteed rate vs. a projected rate
- Surrender charge schedules (how long your money is locked up)
- Whether interest is compounded annually or daily
- Optional riders and their cost
Free tools from carrier websites tend to be optimistic; third-party comparison tools that pull live quotes from multiple carriers give you a more realistic picture.
Lifetime Annuity Calculator: Plan Income You’ll Never Outlive
A lifetime annuity is the only financial product that guarantees you can’t outlive your money. The calculator has to factor in your life expectancy, which is why age and gender matter so much.
Lifetime annuity calculator monthly: single-life vs. joint-life payouts
Single-life pays more per month; joint-life covers both spouses but pays less because the carrier insures two lives. On a $300,000 premium at 65:
- Single-life: ~$1,500–$1,800/month
- Joint-life (same-age spouse): ~$1,300–$1,550/month
Guaranteed lifetime income annuity calculator: QLAC and income rider estimates
A Qualified Longevity Annuity Contract (QLAC) lets you defer income until age 85, using up to $200,000 of IRA money (as of 2024 IRS limits). Because payouts start so late, the monthly check is much larger. A $100,000 QLAC purchased at 65 might pay $2,000+/month starting at 85, because the carrier has had 20 years to grow the premium and a shorter expected payout horizon.
Variable or indexed annuities with income riders work differently: an income base grows at a guaranteed rollup rate (often 5–7%), and your annual payout is a percentage of that base, not the account value.
Lifetime annuity calculator with taxes: how exclusion ratios reduce your tax bill
For non-qualified lifetime annuities, the exclusion ratio calculation divides your investment in the contract by the IRS-expected total payout. That fraction of each payment is tax-free; the rest is ordinary income. Once you’ve received your full principal back (you’ve lived past your life expectancy), every subsequent payment is 100% taxable.
Best lifetime annuity calculator: Fidelity and other tools compared
Fidelity’s income annuity estimator pulls live quotes and lets you compare single vs. joint life and period-certain options side by side. It’s one of the more transparent free tools available. Other solid options include tools from TIAA and Blueprint Income, which aggregate multiple carrier quotes simultaneously.
30-Year Annuity Calculator: Long-Term Payout Projections
A 30-year period-certain annuity guarantees payments for exactly 30 years, regardless of whether you’re alive or not. It’s a common structure for lottery winnings, structured settlements, and long-horizon retirement income.
30-year annuity calculator with taxes: projected after-tax income
For non-qualified contracts, the exclusion ratio spreads your original premium across 360 monthly payments. If you invested $300,000 and receive $1,200/month for 30 years ($432,000 total), roughly 69% of each payment ($828/month) is tax-free return of principal. The remaining $372/month is taxable as ordinary income.
30-year annuity calculator S&P 500: indexed growth scenarios
Some 30-year annuities are fixed-indexed, linking interest credits to S&P 500 performance (with a cap and a floor of 0%). A calculator for these products typically shows three scenarios: low (1–2% credited annually), mid (4–5%), and high (6–7%). Returns are never guaranteed, but the floor means you won’t lose principal due to market drops.
Best 30-year annuity calculator tools to use
For a 30-year period-certain, most carrier calculators handle this well since the math is straightforward. For indexed products, look for tools that show cap rates, participation rates, and historical back-testing — not just a rosy projected return.
5-Year Annuity Calculator: Short-Term Guaranteed Growth
A 5-year MYGA is the annuity world’s answer to a 5-year CD, typically offering a higher guaranteed rate with tax-deferred growth.
How a 5-year MYGA stacks up against CDs and bonds
| Product | Typical Rate* | Tax Treatment | FDIC/SIPC? |
|---|---|---|---|
| 5-Year CD | 4.0–4.5% | Taxable annually | FDIC-insured |
| 5-Year Treasury | 4.2–4.7% | Federal taxable | Backed by U.S. gov’t |
| 5-Year MYGA | 4.5–5.5% | Tax-deferred | State guaranty fund |
Rates fluctuate; check current quotes before deciding.
MYGAs defer taxes until withdrawal, giving your growth a compounding advantage over CDs in higher tax brackets.
5-year annuity calculator monthly: what your deposits earn
A $100,000 MYGA at 5% grows to roughly $127,628 after 5 years. If you then annuitize that into a 20-year income stream, you’d receive approximately $750–$850/month (before tax), depending on rates at annuitization.
Annuity Calculator for Lottery Winnings: Lump Sum vs. Annuity
Winning a major lottery jackpot comes with a choice: take the cash now or receive payments over time. Most state lotteries spread the annuity over 29–30 years with annual payments that increase by about 5% per year.
How lottery annuity payout calculators work
A lottery annuity calculator takes the advertised jackpot, applies the annuity payment schedule (usually escalating 5% annually), and then estimates federal and state tax withholding on each payment. The advertised jackpot is the sum of all future payments before taxes — not what you actually receive.
30-year lottery annuity payout schedule breakdown
On a $100 million jackpot paid over 30 years with 5% annual increases:
- Year 1: ~$1.5 million before taxes
- Year 15: ~$3.1 million before taxes
- Year 30: ~$6.3 million before taxes
After federal taxes (37% top rate) and state taxes, each payment loses roughly 40–45% in most states.
Lump sum vs. annuity calculator: which wins after taxes?
The cash option is typically 50–60% of the advertised jackpot. After the 37% federal rate, a $100 million jackpot’s $60 million lump sum becomes roughly $37–$38 million in hand. The 30-year annuity delivers more total dollars on paper, but the time value of money and investment returns on a lump sum can close the gap — or widen it — depending on what you do with the cash. There’s no universal right answer; it depends on your tax situation, investment discipline, and whether you trust yourself to manage a large lump sum.
Best Annuity Calculators by Provider: Fidelity, Vanguard, and More
Not all free calculators are created equal. Here’s how the major providers compare.
Immediate annuity calculator Fidelity: features and limitations
Fidelity’s income annuity estimator is one of the most robust free tools. It pulls actual quotes from multiple carriers, lets you compare single vs. joint life, and shows how a COLA option changes your starting payment. Limitation: it only covers immediate annuities, not deferred or indexed products.
Immediate annuity calculator Vanguard: what it does and doesn’t show
Vanguard’s annuity calculator provides ballpark estimates but routes you toward their partner carrier (Income Solutions by Hueler). It’s useful for quick estimates but less useful for comparing rates across the broader market.
Best monthly annuity calculator Fidelity: income rider estimates
For deferred income riders attached to variable annuities, Fidelity’s planning tools integrate with their portfolio analysis, which is helpful for seeing how an income rider interacts with your overall retirement picture. However, for standalone income rider estimates, Blueprint Income and Cannex are more specialized.
When to use a free annuity calculator vs. talking to an advisor
Free calculators are great for orientation — understanding the range of what’s possible with your premium. But once you’re ready to actually buy, talk to a fee-only advisor or get quotes directly from multiple carriers. Annuity contracts are complex, and small differences in surrender periods, rate guarantees, and rider costs add up to thousands of dollars over time.
How to Use an Annuity Payout Calculator: Step-by-Step
Step 1: Choose your annuity type (immediate, fixed, lifetime)
Start with your goal. Need income right now? Immediate annuity. Want to grow a lump sum tax-deferred and convert later? Fixed or deferred. Want guaranteed income you can never outlive? Lifetime annuity or QLAC.
Step 2: Enter your premium, rate, and term
Use the actual amount you plan to invest — don’t round up to feel better about the number. Enter the guaranteed rate for fixed products; for variable or indexed, use a conservative mid-rate scenario.
Step 3: Factor in taxes using the exclusion ratio
If your annuity is non-qualified, divide your premium by the total expected payout to find your exclusion ratio. That percentage of each payment is tax-free. The rest gets added to your ordinary income.
Step 4: Compare multiple quotes before you decide
No single carrier has the best rate on every product type. Pull quotes from at least three carriers before signing anything. Rates can vary by 10–15% for the same premium and payout structure, which translates to real dollars every month.
What is the biggest disadvantage of an annuity? Lack of liquidity is the biggest drawback. Your premium is committed for the surrender period — often 7–10 years — and early withdrawals trigger surrender charges plus a possible 10% IRS penalty if you’re under 59½. For money you might need in an emergency, keep it somewhere more accessible.
Frequently Asked Questions
How much does a $100,000 annuity pay per month?
A $100,000 single-premium immediate annuity typically pays $500–$600 per month for a 65-year-old with a single-life payout. Younger buyers receive less per month because the carrier expects to pay longer; older buyers receive more. Adding a period-certain guarantee or joint-life option lowers the monthly amount slightly.
How much would a $500,000 annuity pay annually?
A $500,000 SPIA at age 65 pays approximately $30,000–$36,000 per year on a single-life basis, or roughly $2,500–$3,000 per month. Annual payouts are higher for older buyers and lower when you add inflation protection or joint-life coverage.
How much does a $600,000 annuity pay per month?
A $600,000 immediate annuity at 65 pays approximately $3,000–$3,600 per month for a single-life contract. A joint-life option covering a same-age spouse lowers that to roughly $2,600–$3,100 per month, depending on the carrier and current rate environment.
How much will a $250,000 annuity pay per month?
A $250,000 SPIA for a 65-year-old typically generates $1,250–$1,500 per month on a single-life payout. Adding a 10-year period-certain guarantee — so your heirs continue receiving payments if you die early — reduces the monthly amount by roughly 5–7%.
What is the biggest disadvantage of an annuity?
Liquidity. Once your premium is in, it’s committed for the surrender period (often 7–10 years), and early withdrawals trigger surrender charges. If you’re under 59½, the IRS may also add a 10% early-withdrawal penalty. Annuities work best for money you’re confident you won’t need in the short term.
How much will a $1,000,000 annuity pay monthly?
A $1,000,000 single-premium immediate annuity pays approximately $5,000–$6,000 per month for a 65-year-old on a single-life basis. That’s $60,000–$72,000 per year — before taxes. After applying the exclusion ratio on a non-qualified contract, a meaningful portion of each payment may be tax-free.
How much does a $1 million dollar annuity pay per month?
Same answer as above: roughly $5,000–$6,000 per month at 65 on a single-life SPIA. At 70, the same $1 million might pay $5,800–$7,000/month because the payout period is shorter. Rates vary by carrier, so comparing quotes is essential at this premium level.
What is the difference between an immediate and a deferred annuity calculator?
An immediate annuity calculator skips straight to payouts — you enter your lump sum and it shows what income starts next month. A deferred annuity calculator has two phases: it first projects how your premium grows during the accumulation period, then estimates what payout you’d receive when you convert to income. Deferred calculators require an assumed growth rate, which makes them less precise.
Do annuity payouts get taxed, and how does the exclusion ratio work?
For non-qualified annuities (funded with after-tax dollars), each payment is split between a tax-free return of principal and taxable income. The exclusion ratio equals your original premium divided by the IRS-expected total payout. That fraction of each payment is tax-free; the rest is ordinary income. Qualified annuities (from IRA/401(k) funds) are fully taxable because contributions were pre-tax.
Is a lottery annuity or lump sum better after taxes?
It depends on your tax situation and investment discipline. The lump sum is typically 50–60% of the advertised jackpot, then taxed at 37% federally — you walk away with roughly 35–40 cents on the dollar immediately. The annuity delivers more total dollars over 30 years but loses value to inflation and taxes along the way. If you’re a disciplined investor, the lump sum often wins mathematically; if you’re not, the annuity acts as a forced savings plan.
