Savings Calculator: See Your Money Grow
Enter your starting balance, what you can add each month, and your account's APY to see exactly how much you'll have — and how much of it is interest versus your own money.
How This Calculator Works
Every month, your balance earns interest based on your account's APY (annual percentage yield), and that interest gets added to your balance before the next month's interest is calculated — this is compounding, and it's why the "interest earned" portion grows faster the longer you leave money in the account. Adding a consistent monthly deposit on top of compounding is one of the most reliable ways to build savings, since you're not just relying on growth from interest — you're combining it with your own contributions.
