What is the Money to Put Away to Make Equal Payments Calculator?

The Money to Put Away to Make Equal Payments Calculator is a financial tool that helps you determine the initial amount of money you need to deposit to make equal payments over a specific period. This is commonly used for:

How to Use the Calculator

Using the calculator is simple. Follow these steps:

Enter the desired payment amount you want to make each period
Specify the interest rate (annual percentage rate)
Enter the number of periods (months, years, etc.)
Click "Calculate" to see the required initial deposit

The calculator will display the amount you need to put away now to make the equal payments over the specified period.

The Formula

The calculation uses the present value of an annuity formula:

PV = PMT × [1 - (1 + r)^-n] / r

Where:

PV = Present Value (amount to put away now)
PMT = Payment amount per period
r = Interest rate per period
n = Number of periods

This formula accounts for the time value of money and compounding interest to determine the initial deposit needed.

Worked Example

Let's say you want to make monthly payments of $500 for 5 years at an annual interest rate of 6%. Here's how the calculation works:

Convert the annual rate to a monthly rate: 6% ÷ 12 = 0.5% or 0.005
Calculate the number of periods: 5 years × 12 = 60 months
Plug the values into the formula:
PV = 500 × [1 - (1 + 0.005)^-60] / 0.005
The calculation results in approximately $28,850. This is the amount you need to put away now to make $500 monthly payments for 5 years at 6% annual interest.
