- P = initial deposit, r = monthly rate, n = months, PMT = monthly contribution

Frequently Asked Questions
How does compound interest work?
Your interest earns interest. With monthly compounding, each month's interest is added to the balance and earns interest in subsequent months. This creates exponential growth over time.
What return rate should I use?
High-yield savings: 4-5%. Bonds: 3-5%. Stock market average: 7-10%. Use a conservative estimate for planning purposes.
How much should I save each month?
The 50/30/20 rule suggests saving 20% of after-tax income. But any amount helps — even $100/month becomes $16,470 in 10 years at 5%.
Is this guaranteed?
Savings accounts and CDs have FDIC insurance up to $250,000. Investment returns are not guaranteed and can fluctuate significantly.
Is the Savings Calculator free to use?
Yes, completely free with no signup required. Use it as many times as you need — there are no limits or hidden fees.
