OmniCalcsSavings Calculator
Estimate how your savings balance will grow with monthly deposits and a compounding APY.
How to Use This Savings Calculator
Enter the amount you have saved already, how much you add each month, the APY your account pays and how many years you plan to save. Pick the compounding schedule and see the projected balance and interest earned.
- Initial deposit โ the balance you start with today.
- APY โ the annual percentage yield, which already reflects compounding.
- Compounding โ how often interest is credited to the account.
- Interest earned โ the future balance minus everything you deposited.
Practical Example
Suppose you start with $2,000 and add $150/month at 4% APY compounded monthly:
- After 5 years โ $12,400 (you deposited $11,000)
- After 10 years โ $26,200 (you deposited $20,000)
- After 20 years โ $58,000 (you deposited $38,000)
The gap between deposits and balance is the compounding interest working for you.
What Your Results Mean
- Final balance โ your projected savings including interest.
- Total deposited โ the money you actually put in, to isolate growth.
- Interest earned โ the compounding growth on top of deposits.
Frequently Asked Questions
What is the difference between APR and APY?
APR is the simple annual rate; APY is the effective yield including compounding. A 4% APY means your money grows 4% per year when interest is reinvested.
How does compounding frequency change my savings?
Interest credited monthly earns interest sooner than interest credited yearly. For the same APY the differences are small, but over decades monthly compounding adds up.
Can I use this for a specific savings goal?
Yes. Adjust the monthly deposit or years until the future balance reaches your target. Working backwards this way shows the trade-off between deposit size and time.
Do banks really pay interest every month?
Many high-yield savings accounts credit interest monthly. Some credit quarterly. The compounding setting should match your actual account.
What if APY changes over time?
Rates move with the market. The projection assumes a fixed APY, so if rates rise or fall your actual balance will differ. Recalculate with a conservative rate.
