Frequently Asked Questions about the Savings Calculator
How does the calculator compute growth?
It steps through every month: your contribution is added first, then interest compounds on the full balance. The annual rate is converted into an equivalent monthly rate using the compound frequency you select, so daily, monthly, quarterly, or any other frequency is handled accurately.
Can you walk through an example?
Start with $5,000, contribute $400 a month at 4.5% compounded monthly for 10 years. Your final balance is about $68,500. You put in $53,000 out of pocket and the remaining $15,500 came from interest. Results are estimates, since actual account terms may vary.
Which compound frequency should I pick?
High-yield savings accounts and money market funds typically compound daily. CDs often compound monthly or semi-annually. US Treasury bonds pay interest semi-annually. Match the frequency stated in your account agreement for the most accurate projection.
Are the results pre-tax?
Yes, all figures are pre-tax. Interest on taxable accounts is taxed as ordinary income each year. To approximate your after-tax growth rate, multiply your annual rate by (1 - your marginal tax rate) and enter that adjusted figure instead.
How do tax-advantaged accounts affect the math?
Roth IRA, HSA, and 529 withdrawals for qualified expenses are tax-free, so the gross growth shown here closely reflects real gains. Traditional IRA and 401(k) balances are tax-deferred, meaning you owe income tax on withdrawals in retirement, so the displayed figure overstates spendable dollars for those accounts.
