What is an annuity payout calculator?
An Annuity Payout Calculator shows how much regular income a lump sum can pay over a fixed number of years while the remaining balance keeps earning a return, or how long the money will last if you take a fixed amount. It is useful for planning withdrawals from retirement savings or estimating a fixed-period annuity. It does not price lifetime annuities, whose payments depend on age and the insurer’s terms.
How to use it
- Choose Fixed length to find the payment, or Fixed payment to find how long the money lasts.
- Enter the starting principal and the interest or return rate.
- Enter the years to payout, or the payment amount you want.
- Choose monthly, quarterly or annual payments and click Calculate.
Annuity payout formula
PMT = PV × r ÷ (1 − (1 + r)^−n)
where PMT is each payment, PV is the starting balance, r is the return per payment period and n is the number of payments. The balance earns a return while it is being paid out, so the payments add up to more than the starting amount.
Examples (5% return, monthly payments)
- $100,000 paid out over 20 years: about $659.96 a month.
- $300,000 over 20 years: about $1979.87 a month.
- $2,000,000 over 30 years: about $10736.43 a month.
Types of annuity payouts
Annuities can pay out in several ways:
- Fixed period: equal payments for a set number of years. This is what the calculator models.
- Fixed amount: a set payment until the money runs out. The calculator’s Fixed payment mode covers this.
- Life annuity: payments for as long as you live, priced by an insurer using your age and life expectancy.
- Joint and survivor: payments that continue for a spouse after the first death.
- Period certain: lifetime payments with a guaranteed minimum number of years.
The calculator covers fixed-period and fixed-amount payouts only. For lifetime options, ask insurers for quotes.
What affects an annuity payout?
- Starting balance: more money supports bigger payments.
- Return rate: a higher rate raises each payment.
- Payout period: spreading the money over more years lowers each payment.
- Payment frequency: monthly, quarterly or yearly.
- Fees: contract charges reduce the money available for income.
- Taxes: payments from pre-tax money are fully taxable; for annuities bought with after-tax money, part of each payment is a tax-free return of principal.
Tips
- Use a conservative return; if returns fall short, the money runs out sooner.
- Fixed payments lose buying power to inflation. Consider planning for rising expenses.
- Compare insurer quotes for life annuities with the fixed-period results here.
- Keep some savings outside the annuity for emergencies.
