How is the ending balance calculated?

The ending balance is calculated by applying compound interest to your initial deposit and monthly contributions over the specified savings period. The formula accounts for both your contributions and the interest those contributions earn.

What is compound interest?

Compound interest means you earn interest on both your principal and the interest already accumulated. The more frequently interest compounds, the faster your savings grow.

What compounding frequency should I choose?

Most savings accounts compound interest monthly. Some high-yield accounts compound daily. The more frequently interest compounds, the slightly higher your ending balance will be.

What is the difference between total contributions and ending balance?

Total contributions is the sum of your initial deposit plus all monthly contributions made over the savings period. The ending balance is your total contributions plus all the interest earned. The difference between them is your total interest earned.
