Texas family
$95k household income, two auto loans. Refinancing a 22% APR card into a 5-year 11% personal loan saves ~$4,200 in interest.
California renter
Single filer earning $110k in LA — a 45% DTI locks out most conventional mortgages until credit-card debt is paid down.
Florida retiree
Fixed Social Security + pension. Keeping utilization under 10% preserves the 780+ FICO needed for the best HELOC rates.

Overdraft Fee Impact Calculator: Your result is an estimate of the payment, interest, or payoff that matches the inputs above. It's a directional number to compare offers — not a lender quote.
What your result means
- A lower monthly payment often means a longer term and more total interest paid over the life of the loan.
- A higher APR compounds faster — even a 0.5% difference can add thousands over 30 years.
- Total interest is a better comparison metric than the monthly payment alone.

Common mistakes to avoid
- Mixing APR with the nominal rate — the APR includes fees.
- Entering annual rate as a decimal (e.g. 0.07 instead of 7).
- Forgetting taxes, insurance, HOA, or PMI when comparing homes.
- Ignoring extra payments — even $50/month can shave years off a loan.
Pro tips
- Compare APR — not just the nominal rate — across offers.
- Model a scenario with an extra $50–$100/month; the interest savings can be dramatic.
- Check the amortisation schedule to see when you cross the interest-vs-principal midpoint.
Why use this calculator
- Instantly compare loan offers side-by-side without a lender pitch.
- See the full amortization schedule — interest vs principal, month by month.
- Model extra payments and refinancing scenarios in seconds.
- 100% free, no signup, no credit pull, no data stored on our servers.
Limitations to keep in mind
- APR shown by a lender may differ due to fees, points and credit tier.
- Does not replace a Loan Estimate or Truth-in-Lending disclosure.
- Assumes fixed rate — variable-rate products may behave differently.
- Not a commitment to lend and not a substitute for lender underwriting.
Key terms explained
- APR (Annual Percentage Rate)
- The yearly cost of a loan expressed as a percentage — includes the interest rate plus most lender fees, so it's the fair number to compare offers with.
- Principal
- The amount you actually borrow (or currently owe), before any interest is added. Every payment splits between principal and interest.
- Amortization
- The schedule that shows how each payment is divided between interest and principal. Early payments are mostly interest; later payments are mostly principal.
- DTI (Debt-to-Income)
- Monthly debt payments divided by gross monthly income. U.S. lenders typically prefer a DTI at or below 36–43%.
- Escrow
- A lender-managed account that collects property taxes and homeowners insurance monthly, then pays them on your behalf when due.
Before you decide
- Confirm the quoted rate is APR (not just the note rate) so fees are included.
- Check whether the payment includes taxes and insurance (escrowed) or just principal + interest.
- Ask about prepayment penalties before committing to any extra-payment plan.
- Compare at least 3 lender offers — a 0.25% rate difference matters over 15–30 years.
