About this calculator
An annuity payout calculator turns a lump sum into a stream of equal payments that exhausts the balance over a chosen period, while the remaining balance keeps earning interest. It answers "how much can I withdraw each month from my savings for the next N years?" — useful for retirement drawdown planning.
Frequently asked questions
How is the payout amount calculated?
It is the annuity payment formula PMT = PV × i ÷ (1 − (1 + i)^−n), the same maths as a loan payment. The balance earns interest between withdrawals, so total payouts exceed the starting balance.
Is this the same as a lifetime annuity from an insurer?
No. This is a fixed-term drawdown that runs the balance to zero over the period you choose. A lifetime annuity from an insurer instead pays until you die and prices in mortality, so its payout can differ.
