Frequently asked

What is compound interest in plain English? It's interest that earns interest. Your money grows, and then that growth earns its own growth. The longer you wait, the bigger the snowball.
Is this calculator good for college savings? Absolutely. Plug in your child's age, your monthly contribution, and a realistic rate to see what their fund could look like by freshman year.
How is this different from a loan calculator? A loan calculator shows what you'll pay over time on borrowed money. This tool shows what you'll earn over time on money you save or invest.
Can I use this for retirement planning? Yes — it's a great companion to a 401k calculator. Enter your balance, monthly contribution, and expected return to project your nest egg.
Does the tool factor in taxes? No, results are pre-tax. For after-tax projections, pair it with an income tax calculator to estimate what you'll keep.
What rate should families use? Savings accounts run 4-5%, while long-term stock market averages hover around 7%. Pick what matches where your money lives.
Can I model paying off a car early? Not quite — for vehicle financing, an auto loan calculator is the better fit. This tool focuses on growing savings, not paying down debt.
