How to Use the Simple Savings Calculator

You need to know these four numbers in order to use this savings calculator: 

  1. Current Amount You Already Have Saved - This could also be your initial deposit 

  2. Your Monthly Savings Amount - What you plan to put in the account each month

  3. The Annual Rate of Return - How much interest your account earns each year

  4. The number of years you plan to save 

It’s okay if you don’t have these numbers all figured out yet: You can run the calculation as many times as you need in order to see what it would look like if you saved a different amount each, found a higher interest rate, etc. 

Savings Calculator Example

Say that you currently have $5,000 in savings and are able to save $400 per month over a 30-year period. You also think that you can achieve a 7% return on your money each year. 

Enter “$400” as the Monthly Savings Amount, “30” as the Number of Years and “7%” as the Annual Rate of Return. If you already have $5,000 saved up, enter “$5,000” as your Current Amount Saved.

How Much You’d Earn

If you start with $5,000 and save an additional $400 each month (while earning 7.00% on your investment), you will have accumulated $528,570.89 after 30 years.
