Discount factor: Using a Discount Factor on a Cash Flow
A discount factor is the multiplier that converts a future amount into present value. Calculate it once for a rate and date, then apply it to cash flows at that date.
Use the Discount factor Calculator to enter your own figures and compare the result with the worked example below.
Discount factor formula
Discount factor = 1 ÷ (1+r)^n
Worked example

These are illustrative inputs, not current prices, rates or recommended targets. Where a currency is shown, keep all comparable money amounts in the same currency; conversion examples identify the two sides separately.
How to interpret the result
Each payment date needs its own factor. Keep the period count consistent with the rate and do not apply one factor to an entire uneven schedule.
