What is FV of Annuity?

The future value of an annuity calculates the total accumulated value of a series of equal, equally-spaced contributions made over time, each earning compound interest. It is the key formula behind retirement savings projections: if you contribute a fixed amount each period to a 401(k) or IRA, FVA tells you the nest egg you will accumulate by a given date. Unlike simple compounding of a single lump sum, FVA accounts for the fact that each contribution earns compound interest for a different number of periods.

Formula

FVA = PMT × [(1 + r)^n − 1] ÷ r

Worked Example

30-year horizon at 7% annual return

Step 1 Annual contribution (PMT): $6,000 (IRS limit for 2024 under age 50)

Step 2 Annual return rate: 7% (long-run equity estimate)

Step 3 Periods: 30 years

Step 4 FVA = $6,000 × [(1.07)^30 − 1] / 0.07 = $6,000 × 94.461 = $566,765

Step 5 → Contributing $6,000/year for 30 years at 7% accumulates ~$566,765

< 50000

Small Accumulation — increase contributions or rate

50000 – 500000

Solid Nest Egg — on track for retirement

> 500000

Strong Accumulation — compounding in full effect
