The Present Value of Annuity Calculator determines the current lump-sum equivalent of a series of equal future payments discounted at a given interest rate. This is the essential tool for valuing any stream of fixed payments, from pension benefits and lottery winnings to lease obligations and structured settlements.
The present value of annuity (PVA) answers a fundamental question: 'What is a series of future payments worth today?' The formula for an ordinary annuity is PVA = PMT × [(1 - (1 + r)-n) / r], where PMT is the periodic payment, r is the per-period discount rate, and n is the total number of periods. This formula sums up the individual present values of every single payment in the series.
This calculation is used throughout finance. Pension funds use it to determine how much capital is needed today to fund future retirement payments. Insurance companies use it to price annuity products. Courts use it to calculate lump-sum equivalents of structured settlements. Lessees use it to determine the present value of lease obligations for balance sheet reporting under IFRS 16 and ASC 842.
The discount rate dramatically affects the result. At 4%, a 20-year stream of $1,000 monthly payments is worth $165,022 today. At 8%, the same stream is worth only $119,554 — a 28% reduction. This sensitivity to the discount rate is why financial professionals spend considerable effort selecting the appropriate rate, which should reflect the risk and opportunity cost of the cash flows.
Understanding PVA also helps consumers make better decisions about lump sum vs. annuity choices. When lottery winners or retirees face this choice, comparing the offered lump sum to the calculated present value of the annuity payments reveals which option provides more value. If the offered lump sum exceeds the PVA, take the lump sum; if it's less, the annuity payments are more valuable.
The formula for an ordinary annuity is: PVA = PMT × [(1 - (1 + r)-n) / r]
For an annuity due, multiply by (1 + r). The formula effectively sums the individual present values PV₁ + PV₂ + ... + PVₙ where each PVₖ = PMT / (1+r)^k.
The Present Value of Annuity tells you the lump-sum amount that is financially equivalent to receiving all future payments. Total Payments Received is the simple sum of all payments (PMT × n) without discounting. The Total Discount shows how much the time value of money reduces the nominal total — it's the 'cost' of having to wait for the money.

It is the current lump-sum value of a series of equal future payments, discounted at a specified rate. It tells you how much money you would need to invest today to replicate the same payment stream.
Use it when you need to value a stream of fixed payments: pension benefits, lease obligations, lottery winnings, structured settlements, bond coupon payments, or any regular income stream.
Calculate the PVA of the annuity payments using an appropriate discount rate. If the offered lump sum exceeds the PVA, take the lump sum. If the lump sum is less than the PVA, the annuity is the better deal.
It depends on the context: risk-free rate (2-4%) for guaranteed payments like government pensions, corporate bond yields (4-7%) for corporate obligations, or your expected investment return (6-10%) for personal decisions.
An ordinary annuity has payments at period end (most common: loan payments, dividends). An annuity due has payments at period start (rent, insurance premiums). Annuity due has a higher present value because payments are received sooner.
As the number of periods increases, PVA increases but at a decreasing rate. Each additional payment adds less present value because it is discounted more heavily. Eventually, a perpetuity (infinite annuity) approaches PMT/r as its limit.
A perpetuity is an annuity that continues forever. Its present value is simply PV = PMT / r. For example, a $100/year perpetuity at 5% is worth $2,000 today. Perpetuities are theoretical but approximate long-lived cash flow streams.
Under IFRS 16 and ASC 842, lessees must calculate the present value of all future lease payments to recognize a right-of-use asset and lease liability on the balance sheet. The discount rate is typically the lessee's incremental borrowing rate.
Yes, the mortgage balance is the present value of all remaining payments. The standard loan payment formula PMT = PV × r / (1 - (1+r)^-n) is derived directly from the PVA formula solved for PMT.
PVA moves inversely with interest rates. When rates rise, PVA falls because future payments are discounted more heavily. When rates fall, PVA rises. This is the fundamental mechanism behind bond price changes.
