Annuity Income Break-Even Age Calculator

Estimate the age at which cumulative after-tax annuity income equals the premium or purchase amount you want to recover. This break-even view is useful when comparing the cash-flow side of an income annuity with its upfront cost and when testing how taxes change the time needed to receive an equivalent amount back through payments.

The calculator uses a constant annual income and applies your taxable-percentage and marginal-tax assumptions before determining the recovery period. It does not attempt to value mortality credits, insurer guarantees, investment alternatives, inflation, survivor benefits, or surrender values. Those factors can be important in an annuity decision, so the break-even age should be treated as one comparison point rather than a complete measure of value.

1. Enter the premium
Use the amount paid or allocated to the annuity that you want to recover through income.

2. Enter the starting age
Use the age when the modeled income stream begins.

3. Enter annual income
Use the gross yearly annuity income before taxes.

4. Describe the taxable share
Enter the percentage of the annual payment you expect to treat as taxable in this scenario.

5. Add tax assumptions
Enter federal and state or local marginal rates, then compare the years and age required for after-tax income to equal the premium.

Taxable annual income = gross annual income × taxable portion Estimated annual tax = taxable annual income × (federal rate + state/local rate) After-tax annual income = gross annual income − estimated annual tax Years to break even = premium ÷ after-tax annual income Break-even age = starting age + years to break even

The calculation assumes level annual income and constant tax assumptions. It does not discount future payments or model investment returns on the premium.

What the result means

The break-even age is the modeled age when cumulative after-tax annuity payments equal the premium entered.

Living beyond the break-even age does not by itself prove that one financial choice is better because liquidity, guarantees, alternatives, inflation, and survivor provisions are not included.

Given

  • Premium: $250,000
  • Income starts at age 65
  • Gross annual income: $20,000
  • Taxable portion: 100%
  • Combined assumed tax rate: 25%

Calculation
Estimated annual tax = $20,000 × 25% = $5,000
After-tax annual income = $20,000 − $5,000 = $15,000
Years to break even = $250,000 ÷ $15,000 = 16.67 years
Break-even age = 65 + 16.67 = 81.67

Result
Estimated break-even age is about 81.7.

Under these assumptions, cumulative after-tax payments reach the entered premium roughly 16 years and 8 months after income starts.

Is this the same as an annuity internal rate of return?

No. Break-even age simply asks when cumulative modeled payments equal the entered premium. An internal-rate-of-return analysis also accounts for the timing of each cash flow.

Why use after-tax income for break-even?

Taxes can reduce the amount available to recover the original outlay. Using an after-tax payment stream gives a cash-flow perspective based on the tax assumptions you enter.

What if part of my annuity payment is tax-free?

Enter a taxable portion below 100%. The calculator will apply the assumed tax rates only to that portion of annual income.

Does the calculator account for death benefits or period-certain guarantees?

No. Contract guarantees and beneficiary provisions can materially affect value but are outside this simple cumulative-income comparison.

What if the after-tax annual income is zero?

A break-even age cannot be calculated because no modeled cash flow is available to recover the premium. Review the income and tax assumptions in that case.
