Annuity Calculator

Free annuity calculator to forecast the growth of an annuity with optional annual or monthly additions.

How to Use the Annuity Calculator

Enter present value, contribution or premium amount, expected return, payout timing, and term assumptions. Calculate to estimate future annuity value or required premium for target income.

Formula: Common forms: FV = P(1+r)^n for lump sum growth; annuity future value adds periodic contributions. Payout estimates depend on discount rate and term.

Accumulation vs Income Phase

Annuity planning requires separate modeling for growth years and payout years.

Rate and Term Sensitivity

Small assumption differences can significantly change long-horizon annuity projections.

Income Stability Goals

Annuities are often used to reduce longevity risk through predictable cash-flow support.

Cost and Product Structure

Fees, riders, and guarantee structure should be evaluated alongside projected returns.

Portfolio Integration

Annuity decisions are strongest when coordinated with total retirement-income strategy.

Can annuity income be fixed?+

Yes, fixed annuities target stable payouts, while variable annuities can fluctuate with investment performance.

What is annuitization?+

How does inflation affect annuity income?+

Inflation can reduce purchasing power unless payouts include inflation adjustment features.
