How to Use This Calculator
- Enter the number of terms (n).
- Enter the interest rate (r).
- Enter the cash flow amount.
- Click ‘Calculate’.
Formula & Methodology
The formula for calculating the present value of a series of cash flows is:
PV = CF / (1 + r)^n
Where:
- PV is the present value.
- CF is the cash flow.
- r is the interest rate.
- n is the number of terms.
Real-World Examples
Example 1: Investment
An investor wants to know the present value of a series of annual cash flows of $1000 over 5 years at an interest rate of 5%.
PV = $1000 / (1 + 0.05)^5 = $772.17
Example 2: Loan
A borrower wants to know the present value of a series of annual loan payments of $1200 over 10 years at an interest rate of 6%.
PV = $1200 / (1 + 0.06)^10 = $613.91

Interactive FAQ
What is the difference between present value and future value?
Present value is the current worth of a future sum of money or stream of cash flows, given a specified rate of return. Future value, on the other hand, is the value of an asset or cash at a specified date in the future.
How does changing the interest rate affect the present value?
As the interest rate increases, the present value decreases. This is because money is worth more today than in the future, so a higher interest rate makes future cash flows less valuable in the present.
