How does this calculator work?
A variable annuity grows during accumulation as FV = PV × (1+r)^n + PMT × [(1+r)^n − 1] / r (r = monthly rate, n = months), then pays a fixed monthly amount over the payout term. Returns track sub-account market performance; this calculator uses a fixed assumed rate for illustration only. Fees and taxes are not included.
Formula
How this is calculated
A variable annuity is a tax-deferred insurance contract with two distinct phases. During the accumulation phase, your initial lump sum and monthly contributions grow inside investment sub-accounts — similar to mutual funds — at a rate driven by market performance. This calculator models that growth at a constant assumed annual rate compounded monthly, applying the standard future-value formula for a lump sum plus recurring contributions.
In the payout (annuitisation) phase, the accumulated balance funds a stream of monthly payments. The calculator uses the present-value-of-annuity formula rearranged for the payment size that exactly exhausts the account over your chosen payout term, again at the same monthly rate. This is the "fixed-period annuity" structure; life-annuity pricing also depends on mortality tables and is not modelled here.
Key limitations: actual variable-annuity sub-account returns are not fixed, so real outcomes will differ from any single assumed rate. Variable annuities also carry insurance charges (mortality and expense fees, typically 1–1.5% annually), fund management fees, and potential surrender charges during an early withdrawal period — this calculator ignores all fees. Withdrawals before age 59½ in the US incur a 10% federal penalty plus ordinary income tax on gains. Use this tool for educational planning only; consult a licensed financial adviser and your annuity contract for precise projections.
Frequently asked questions
A fixed annuity credits interest at a rate guaranteed by the insurer, so growth is predictable and there is no investment risk. A variable annuity invests in sub-accounts (equity, bond, balanced funds) chosen by the owner, so returns fluctuate with markets — offering higher long-run growth potential but carrying investment risk. Some variable annuities include guaranteed-minimum-income or guaranteed-minimum-withdrawal riders that floor the downside at extra cost.
The payout (distribution or annuitisation) phase is when you draw income from the accumulated balance. Options typically include: a fixed-period annuity (payments for a set number of years, exhausting the account); a life annuity (payments for your lifetime, insured by the company); or a systematic withdrawal (you set your own withdrawal rate). This calculator models the fixed-period option using the standard present-value-of-annuity formula.
Inside a variable annuity growth accumulates tax-deferred — no annual tax on dividends, interest, or capital gains. When you withdraw, gains (not the original after-tax principal) are taxed as ordinary income, not as preferential capital-gains rates. Withdrawals before age 59½ generally trigger a 10% federal early-withdrawal penalty in the US. Unlike IRAs and 401(k)s, variable annuities have no annual contribution limits.
