Annuity Payout Calculator

Free annuity payout calculator. Find monthly or annual income from a lump-sum annuity purchase. Compare payout rates for different terms and interest rates.

About the Annuity Payout Calculator

The Annuity Payout Calculator converts a lump sum into a stream of regular income payments. Enter the amount you want to annuitize, the interest rate, and the payout period to see your monthly and annual income.

This is the reverse of a present value calculation — instead of finding what a payment stream is worth, you're finding what payments result from a given lump sum. It's the core calculation behind retirement annuity products, systematic withdrawals, and structured settlements.

Compare how different interest rates and payout periods affect your income to find the right balance of payment size and duration. Even a small change in interest rate can significantly alter your monthly income — a 1% rate increase on a $500,000 balance might add $200 or more per month over a 20-year payout. Understanding this sensitivity is essential when evaluating annuity offers from insurance companies, which often present terms that are difficult to compare without an independent calculation.

Why Use This Annuity Payout Calculator?

Converting a retirement nest egg to guaranteed income is one of the most important financial decisions. This calculator shows exactly how much monthly income you can expect from a given balance, helping you compare annuity quotes and plan systematic withdrawal strategies. It also reveals how rate and time-period trade-offs affect the sustainability of your retirement income.

How to Use This Calculator

  1. Enter your lump sum (investment or annuity purchase price).
  2. Set the annual interest/payout rate.
  3. Choose the payout period in years.
  4. Select payment frequency (monthly or annual).
  5. Review your periodic payment and total income.
  6. Compare the rate sensitivity table for different scenarios.

Formula

PMT = PV × [r / (1 − (1 + r)^−n)] where PV = lump sum, r = periodic rate, n = number of payments Total Income = PMT × n Total Interest = Total Income − PV

Example Calculation

Result: $2,923/month ($35,077/year)

A $500,000 lump sum annuitized at 5% over 25 years produces monthly payments of $2,923. Total income is $876,932, meaning you receive $376,932 in interest earnings above your initial investment.

Tips & Best Practices

The Annuitization Decision

Annuitizing converts a lump sum into a guaranteed income stream. This provides certainty that you won't run out of money, but you lose access to the principal. It's a trade-off between security and flexibility that depends on your other income sources, health, and goals.

Interest Rate Impact

The payout rate is heavily influenced by prevailing interest rates. In a 5% rate environment, payouts are significantly higher than in a 3% environment. Locking in an annuity during low rates means permanently lower income. Timing matters.

Comparison with Systematic Withdrawals

Systematic withdrawals from an investment portfolio offer flexibility and potential upside, but carry market risk. Annuities offer certainty at the cost of inflation erosion (for fixed annuities) and loss of principal. Many retirees use both strategies.

Frequently Asked Questions

How much income can $500,000 generate?

At 5% over 25 years, about $2,923/month. At 4% over 30 years, about $2,387/month. The answer depends on the interest rate and how long you want payments to last. Use this calculator to find the exact amount for your situation.

What's the difference between this and a withdrawal calculator?

An annuity payout guarantees fixed payments for the term. A withdrawal from an investment account depends on market returns and may run out faster or slower. This calculator assumes a fixed rate, making payments predictable and guaranteed.

Are annuity payouts taxable?

Partially. Each payment is split into a return of your investment (tax-free) and earnings (taxable as ordinary income). The exclusion ratio determines the tax-free portion. Once you've recovered your full investment, all subsequent payments are fully taxable.

What happens if I die during the payout period?

It depends on the annuity contract. A "life only" annuity stops. A "period certain" annuity continues to beneficiaries for the guaranteed period. A "joint and survivor" annuity continues to a surviving spouse. More guarantees generally mean smaller payments.

Can I get payments for life?

Yes. Life annuities use actuarial tables instead of a fixed term, paying until death. Payments are higher if you're older (shorter expected payout) and lower for younger annuitants. This calculator uses a fixed term; for life annuities, see the immediate annuity calculator.

Should I annuitize my entire savings?

Most advisors suggest annuitizing only enough to cover essential expenses alongside Social Security. Keep the rest invested for growth, flexibility, and legacy. A 40-60% annuitization rate is common in financial planning.
