How to Calculate Cumulative Present Value

by Carter McBride ; Updated September 26, 2017
Companies can calculate the present value of future cash flows to determine how much the future cash flow is worth today.

If a company is anticipating cash flows in the future, then the company can determine how much those future cash flows are worth today. Due to the time value of money, the present value of future cash flows will be less than the actual amount received in the future. When the company expects cash flows over several future years, it can add the present value of each cash flow to determine the cumulative present value.

Write out the information to create a clear picture of the cash flows. For example, Firm A owes Firm B the following cash flows: $5,000 in year 1, $8,000 in year 2 and $10,000 in year 3. Firm B's applicable interest rate is 5 percent.

Determine the present value factor for each cash flow using the present value of $1 table, available online at In the example, year 1's present value factor is 0.9524, year 2's present value factor is 0.9070 and year 3's present value factor is 0.8638.

Multiply the appropriate cash flow by its corresponding present value factor. In the example, for year 1, $5,000 times 0.9524 equals $4,762. For year 2, $8,000 times 0.9070 equals $7,256. For year 3, $10,000 times 0.8638 equals $8,638.

Add the present value of each cash flow to find the cumulative present value of the cash flows. In the example, $4,762 plus $7,256 plus $8,638 equals $20,656.
