Use this free annuity calculator to estimate how much retirement income an annuity could provide. Enter your lump sum, interest rate, and payout period to see monthly or annual annuity payments in seconds.
An annuity converts a lump sum into a steady income stream. Whether you are comparing a fixed annuity, an immediate annuity, or a deferred annuity, the calculator above gives you a starting estimate. Results are estimates only, not a quote from an insurance company.
Annuity Calculator
The calculator on this page helps you answer one core question: how much monthly or annual income can a given amount of money produce through an annuity?
Enter your principal (the lump sum you plan to invest), choose an interest rate, set the payout period or select a life expectancy estimate, and pick whether you want payments to start now or later. The tool returns an estimated annuity payout so you can compare options side by side.
This is a basic annuity calculator for planning purposes. It does not factor in specific insurance company fees, surrender charges, or tax rules. For a binding quote, contact a licensed insurance professional.
How the Annuity Payout Calculator Works
The calculator uses a standard present value annuity formula. It takes your inputs, applies compound interest math, and divides the result into periodic payments. Below is what each input means and how it shapes your estimate.
Annuity Income Inputs
You need three core numbers to run the calculation:
- Principal (lump sum): The amount you plan to put into the annuity. Common starting points are $100,000, $250,000, or $500,000.
- Payout period: How many years you want payments to last. You can choose a fixed number of years or estimate based on life expectancy.
- Payment frequency: Monthly, quarterly, or annual annuity payments. Monthly is the most common choice for retirement income.
The larger your lump sum and the shorter your payout period, the higher each payment will be. A longer payout period spreads the money further, lowering each monthly amount.
Interest Rate and Deferral Period
The interest rate is the assumed rate of return the annuity earns over time. For a fixed annuity, this is typically a guaranteed minimum interest rate set by the insurance company. For an indexed annuity, returns may be tied to a benchmark like the S&P 500, but with caps and floors.
A higher interest rate produces a larger payout. Even a small difference (say 4% vs. 5%) compounds significantly over a 20-year period.
The deferral period is how long you wait before payments begin. If you set deferral to zero, you are modeling an immediate annuity. If you set it to 5 or 10 years, you are modeling a deferred annuity. More on deferral below.
Lump Sum vs. Annuity Payout
One of the most common retirement decisions is whether to take a lump sum (from a pension, 401(k), or other savings) or convert it into annuity payments.
A lump sum gives you full control and flexibility. You can invest it, spend it, or leave it to heirs. The risk is outliving the money or losing value in a market downturn.
An annuity payout trades that flexibility for predictability. You receive a guaranteed income stream for a set period or for life. The tradeoff is reduced access to the principal and potential surrender charges if you withdraw early.
Use the calculator to compare both scenarios. Plug in your lump sum, then see what the equivalent monthly annuity payment would be. That side-by-side view makes the decision more concrete.
How much does a $100,000 annuity pay per month? At a 5% interest rate over 20 years, roughly $660 per month. The exact amount depends on your rate, payout period, and whether the annuity is immediate or deferred. Run your own numbers above to see a personalized estimate.
How much does a $500,000 annuity pay per year? With a 5% rate and a 20-year payout, approximately $39,600 per year. A life annuity with no period certain could pay more, because the insurance company pools longevity risk.
How much will a $250,000 annuity pay per month? At similar assumptions, roughly $1,650 per month. Shorter payout periods or higher rates push that number higher.
Income Annuities and Immediate Annuities
An income annuity is any annuity purchased primarily to generate regular payments. The most straightforward type is an immediate annuity: you hand over a lump sum, and payments begin within 30 days.
Immediate annuities are popular with retirees who want guaranteed retirement income right away. There is no accumulation phase. You are purchasing an annuity purely for the income stream.
Why consider an income annuity? It removes the guesswork from retirement budgeting. Your monthly payment is locked in regardless of what the stock market does.
Fixed Annuity and Fixed Income Payouts
A fixed annuity pays a guaranteed fixed rate of return for a set period. Your principal grows at that rate during the accumulation phase, and your eventual payout is predictable.
Fixed income payouts appeal to people who want financial security over maximum growth. You will not benefit from a rising S&P 500, but you will not lose money in a downturn either.
What is a fixed annuity? It is a contract with an insurance company that guarantees a stated interest rate for a specific term. Think of it as a cross between a CD and a pension. Your money grows tax-deferred, and you receive predictable payments.
How is a fixed annuity taxed? Earnings grow tax-deferred during the accumulation phase. When you start receiving payments, the portion that represents earnings is taxed as ordinary income. The portion that represents your original principal (your cost basis) is not taxed again. If the annuity is inside an IRA or 401(k), the entire payment is typically taxable.
MYGA (Multi-Year Guaranteed Annuity)
A MYGA is a specific type of fixed annuity. It guarantees a fixed rate for a set number of years, usually 3 to 10. It works much like a bank CD but is issued by an insurance company and grows tax-deferred.
MYGAs are straightforward. You know your rate on day one. There are no moving parts tied to the stock market or an index.
At the end of the MYGA term, you can:
- Renew at a new rate
- Roll the balance into another annuity
- Withdraw the funds (subject to any applicable taxes or surrender charges)
MYGAs are often used during the years just before retirement. They lock in a guaranteed amount of growth while you finalize your income plan.
Defer Your Annuity for Higher Retirement Income
You do not have to start payments immediately. Choosing to defer your annuity, meaning you wait months or years before the first payment, can substantially increase each payout.
How Deferral Affects Your Payout
When you defer, your lump sum continues to earn interest during the deferral period. The longer the money compounds, the larger the pool available to fund payments.
For example, a $200,000 annuity at 5% with payments starting immediately might pay around $1,320 per month over 20 years. Defer for 10 years and the same money could produce roughly $2,150 per month over the remaining period. The exact numbers depend on your inputs, so run the calculator with different deferral lengths to see the impact.
Deferred annuities (sometimes called deferred income annuities) are designed for people who are still working or have other income sources today but want guaranteed lifetime income starting at a future date, such as age 65 or 70.
Life Expectancy and the Annuity Contract
Life expectancy is central to how insurance companies price annuity contracts. A life annuity pays you for as long as you live. The insurance company estimates how long that will be using actuarial tables.
If you are healthier or younger, the per-payment amount on a life annuity is lower because the company expects to make more payments. If you are older, each payment is higher.
The annuity contract spells out the exact terms: payment amount, frequency, deferral period, and what happens when you die (beneficiary provisions). Read the contract carefully before purchasing an annuity. The calculator here helps you understand the math, but the contract is the binding document.
At what age would you purchase the annuity? This matters because your age at purchase affects the interest rate you are offered and the projected payout. Most people purchase between ages 55 and 75. Running estimates at several ages in the calculator can show how timing changes your monthly annuity payment.
Annuity Features and Income Options
Annuities are not one-size-fits-all. Insurance companies offer a range of features and income options that change how payments work, who receives them, and what happens if you die early.
Joint Life Income Options
A joint life annuity covers two people, usually spouses. Payments continue as long as either person is alive.
The monthly payment on a joint life annuity is lower than a single life annuity for the same lump sum. That is because the insurance company expects to pay for a longer combined lifespan. The tradeoff is that your spouse continues to receive income after you pass away.
How old will your joint annuitant be at the time of the annuity purchase? Both ages matter. A younger joint annuitant means lower payments because the expected payout period is longer.
Common joint life options include:
- 100% survivor benefit: The surviving spouse receives the full payment amount.
- 50% survivor benefit: Payments drop by half after the first death. This option produces a higher initial payment.
- 75% survivor benefit: A middle ground.
Beneficiary and Withdrawal Options
If you die before the annuity has paid out the full principal, a beneficiary provision determines what happens to the remaining money.
Some contracts return the remaining balance to your named beneficiary. Others do not, meaning the insurance company keeps the unpaid portion. This is a critical detail to check before purchasing an annuity.
What are surrender fees? A surrender fee (also called a surrender charge) is a penalty for withdrawing money from the annuity before the surrender period ends. Surrender periods typically last 5 to 10 years. The fee often starts at 7% to 10% and decreases each year until it reaches zero.
Most annuities allow a limited annual withdrawal without penalty, often 10% of the account value. Beyond that, surrender charges apply. Factor this into your decision if you think you might need access to the principal.
10-Year Period Certain and Other Payout Choices
A "period certain" option guarantees payments for a minimum number of years, even if you die before the period ends. A 10-year period certain is the most common.
Here is how it works: if you choose a life annuity with a 10-year period certain and you die in year 3, your beneficiary receives payments for the remaining 7 years. If you live past 10 years, payments continue for your lifetime.
Other payout choices include:
- Life only: Payments stop at death. Highest monthly amount, but nothing for heirs.
- Life with 20-year period certain: Same concept as 10-year, but with a longer guarantee. Lower monthly payment.
- Fixed period (no life component): Payments last for an exact number of years regardless of whether you are alive. Simpler math, no longevity risk pooling.
The right choice depends on your need for guaranteed income, your health, and whether you want to leave money to a beneficiary.
Fixed Annuity in a Retirement Plan
Annuities can live inside or outside a retirement plan. Each approach has different tax and planning implications.
401(k) and Pension Rollover to an Annuity
Many people reach retirement with a 401(k) balance or a pension lump sum offer. Rolling that money into an annuity is a common option.
A direct rollover from a 401(k) or traditional IRA into an annuity avoids immediate taxes. The funds remain tax-deferred inside the annuity contract. You pay income tax only when you receive payments.
If you have a Roth IRA, a Roth annuity rollover keeps the tax-free treatment as long as you meet the usual Roth distribution rules.
Does an annuity work for your retirement plan? It depends on your other income sources, your comfort with market risk, and how much guaranteed income you want. An annuity works well as one piece of a broader retirement plan. It does not need to be all or nothing.
Before rolling over a pension or 401(k), compare the pension's built-in annuity option (if offered) with what you could get from a private insurance company. Pension annuity terms are sometimes more favorable because employer plans have lower administrative costs.
Annuity vs. Stock Market Risk
Keeping retirement savings in the stock market offers growth potential. The S&P 500 has averaged roughly 10% annually over long periods. But returns are not guaranteed, and a major downturn early in retirement can permanently damage your portfolio.
A fixed annuity eliminates that sequence-of-returns risk. Your payments stay the same whether the market rises or falls. The downside is that fixed annuity rates are lower than long-term average stock returns, so you sacrifice potential upside for stability.
A fixed indexed annuity offers a middle path. Your returns are linked to an index like the S&P 500, but with a guaranteed floor (often 0%) and a cap on gains. You participate in some market growth without risking principal loss.
Many financial planners suggest using an annuity to cover essential expenses (housing, food, healthcare) and keeping the rest of your retirement savings invested for growth. This approach balances financial security with the ability to keep pace with inflation over time.

Present Value, Fees, and Tax Considerations
The calculator uses a present value formula to estimate annuity payments. It assumes a constant interest rate and does not account for:
- Fees: Real annuity contracts may include additional fees such as administrative charges, mortality and expense charges, rider fees, and surrender charges. These reduce your effective return.
- Taxes: Annuity earnings are taxable as ordinary income when distributed. The tax impact depends on whether the annuity is inside a retirement plan (IRA, 401(k), Roth) or purchased with after-tax dollars. Consult a tax professional for your specific situation.
- Inflation: A fixed payout that looks comfortable today may lose purchasing power over 20 or 30 years. Some contracts offer inflation riders, but they come at a cost.
The estimates here show the math. The actual payout from an insurance company will differ based on your age, health, the company's fee structure, and current annuity rates.
