What the Immediate Annuity Calculator calculates
Values a stream of annuity payments: present value, future value, the payment a lump sum buys, how many payments it supports and the implied interest rate, for ordinary annuities, annuities due, and graduated streams such as a lottery annuity or an escalating structured settlement.
How to use this Immediate Annuity Calculator
Enter Payment each period, Lump sum today, Interest or discount rate and Length of the payment stream. Present value updates as you type. Change one figure at a time to see what drives the result.
How the result is worked out
Open “How this is worked out” beside the result for the step-by-step calculation behind Present value, Future value and Payment each period.
The method follows Annuity identities PV = PMT[1-(1+i)^-n]/i and FV = PMT[(1+i)^n-1]/i, with the annuity-due factor (1+i), Growing-annuity identity PV = PMT/(i-g) x [1 - ((1+g)/(1+i))^n], and n x PMT/(1+i) when i = g and Powerball - Prize Chart (annuity option).
What you can compare
Change one input at a time to see how it affects Present value, Future value and Payment each period. The inputs you can vary are Payment each period, Lump sum today, Interest or discount rate, Length of the payment stream, Payment frequency and Annual escalation of the payment.
Understanding Present value, Future value and Payment each period
This values a payment stream under the assumptions you enter. It is not a quote: a real annuity contract prices mortality, insurer fees, surrender charges, guarantees and tax, and a structured-settlement transfer needs court approval. Take the figures to a qualified adviser before acting on them.
Results are general information, not financial, tax, legal, medical or engineering advice. Check any decision that matters with a qualified professional.
