How is my monthly loan payment calculated?
Fixed-rate loans use standard amortization math based on principal, annual interest rate, and term. The Loan calculator shows the full schedule, not just the payment.
Avalanche or snowball — which debt payoff method saves more?
Avalanche (highest interest rate first) minimizes total interest paid. Snowball (smallest balance first) can build momentum faster. The Debt Payoff calculator compares both for your actual balances.
Should I pay off debt or save first?
As a rule of thumb, prioritize any high-interest debt (above roughly 7–8%) before extra saving, but still capture any employer 401(k) match along the way.
Does a longer loan term always cost more in interest?
Yes, for the same rate — a longer term lowers the monthly payment but increases total interest paid, since the balance stays higher for longer.
Will refinancing my auto loan lower my payment?
It can, if rates have dropped or your credit has improved since you took out the loan. Compare your current terms against a new rate in the Auto Loan calculator.
Does the student loan calculator account for a grace period?
Yes — you can set a deferment or grace period before payments start, and see how it affects the total interest that accrues.
