Annuity Income Break-Even Age Calculator

Estimate the age when cumulative after-tax annuity payments equal the upfront premium. This nominal cash-recovery view adjusts each payment for its taxable share and your entered tax rate, then converts the required number of payments into a break-even age. It is a useful checkpoint for longevity comparisons, but it does not value insurance guarantees, time value of money, survivor benefits, liquidity, or payments received by beneficiaries.

How to use this calculator

  1. Enter the annuity income break-even age terms exactly as shown in your quote or benefit statement.
  2. Use your estimated marginal tax rate, not a withholding percentage unless the field specifically asks for withholding.
  3. Select Calculate to update the estimate and supporting figures.
  4. Compare the result with other income sources, liquidity needs, and the assumptions shown below.

Formula

After-tax payment = monthly payment × [1 − (taxable share × tax rate)]
Break-even months = premium ÷ after-tax monthly payment

What the result means

Use the main result as a scenario estimate and compare it with alternative assumptions. Small changes in tax, return, inflation, or payment terms can compound into meaningful differences.

This is an educational estimate, not tax, investment, insurance, or legal advice. Actual taxes and contract benefits depend on jurisdiction and plan terms.

Example calculation

A $300,000 premium producing $2,200 monthly, with 75% taxable at 24%, pays about $1,804 after tax. Nominal break-even occurs after 167 months, or near age 78.9 when payments start at 65.

Tips for better results

  • Run a conservative case with a lower return or growth assumption.
  • Keep nominal dollars and inflation-adjusted dollars separate when comparing offers.
  • Use the tax rate you expect for this income, which may differ from your current rate.
  • Check contract guarantees, survivor provisions, fees, and early-withdrawal restrictions.
  • Save the assumptions used so future comparisons are consistent.

Frequently asked questions

Does annuity break-even age include investment growth on the premium?

No. This is a nominal cash-recovery calculation and does not add an opportunity cost.

How does the taxable share affect break-even age?

A larger taxable share lowers the estimated after-tax payment and pushes break-even later.

Are partial months rounded?

Yes. Months are rounded up because a full payment is needed to recover the remaining premium.

Does dying before break-even mean the contract had no value?

Not necessarily. Guarantees, survivor payments, and insurance value may still matter.

Can I use this for an inflation-adjusted annuity?

Use the forecast calculator for growing payments; this break-even tool assumes a level payment.
