What is this tool?
Our free savings calculator projects how your money can grow over time with compound interest. Enter your initial deposit, monthly contributions, interest rate, and time horizon to see your future balance. Whether you're saving for retirement, a down payment, or an emergency fund, this compound interest calculator shows the power of consistent saving.
How it works
This investment calculator uses the compound interest formula with monthly contributions. Your initial deposit earns interest, and each monthly contribution also starts earning interest immediately. The more frequently interest compounds (daily vs monthly vs yearly), the faster your money grows.
Where P = initial deposit, PMT = monthly contribution, r = annual rate, n = compound periods/year, t = years.

Frequently Asked Questions
What's the difference between simple and compound interest?
Simple interest is calculated only on your principal. Compound interest is calculated on your principal plus previously earned interest. Compound interest grows much faster, especially over long periods.
How often should interest compound?
More frequent compounding earns more interest. Daily compounding yields slightly higher returns than monthly, which beats yearly. However, the difference narrows at lower rates.
Is this calculator for savings accounts or investments?
Both. Use it for any interest-bearing account: savings accounts, CDs, retirement accounts (401k, IRA), or taxable investment accounts with expected returns.
Tips & Advice
The most powerful factor in saving is time, not the amount. Starting early - even with small amounts - beats starting later with larger contributions. Increase your savings rate by 1% each year to build the saving habit painlessly. Use our savings calculator to set specific, realistic goals and track your progress quarterly. Remember to diversify investments and consider tax-advantaged accounts like 401(k)s and IRAs first.
