Most popular loan calculators
Loan Comparison Calculator
Compare two offers when APR, term, fees, or payment size differ.
Auto Loan Calculator
Estimate vehicle financing with down payment, trade-in, taxes, and fees.
Which calculator should I use?
Use the loan payment calculator for a quick estimate on one fixed-rate loan. Use the loan comparison calculator when choosing between two offers. Use the personal loan affordability calculator when you know the monthly payment you can afford but not the principal amount.
For collateral-specific borrowing, use the auto loan or mortgage calculators because taxes, insurance, down payments, and fees can change the result. For existing balances, use the debt payoff or credit card payoff tools instead of new-loan calculators.

How to choose a loan calculator
Use the general loan payment calculator for a single fixed-rate loan estimate. Use the comparison calculator when two offers have different rates, terms, or fees. Use the auto and mortgage calculators when taxes, down payments, trade-ins, insurance, or property-related costs need to be separated. If rate structure or compounding is the main question, review the interest and inflation tools hub too.
Debt payoff and credit card tools answer a different question: how an existing balance may change when payments are made over time. They are useful for payoff planning, not for comparing new loan offers.
What to compare beyond the monthly payment
A smaller monthly payment can come from a longer term, not a cheaper loan. Check total interest, total repayment, fees, prepayment rules, variable-rate risk, and whether optional products are included. The guides below explain these tradeoffs in more detail.

Use loan results as estimates, not approvals
Loan calculators can show how principal, APR, term, extra payments, fees, and down payments change a simplified payment or payoff timeline. They cannot predict approval, underwriting, exact APR, insurance, taxes, lender fees, or local disclosure rules.
For a stronger comparison, open the relevant calculator, change one assumption at a time, then read the related guide before comparing real offers.
Scope, sources, what to verify
- Scope: This hub organizes the main loan calculators and guides, but it does not replace lender disclosures or contract review.
- Sources: Loan agreements, APR disclosures, fee worksheets, payment schedules, and any lender instructions on extra payments or payoff rules.
- What to verify: APR vs nominal rate, term length, financed fees, prepayment rules, and whether related costs or lender conditions are missing from the simplified model.
For methodology, review How We Calculate. For sourcing and corrections standards, review Editorial Policy. For best results, pair each calculator with the matching guide before comparing real offers.
Before you rely on a result
- Compare total repayment, fees, term length, and payment size instead of only the monthly number.
- Run at least one higher-rate or longer-term scenario to see how sensitive the estimate is.
- Verify real offers with official documents such as loan estimates, promissory notes, lender disclosures, payoff statements, and account agreements.
Loan tools are best used to prepare questions and compare assumptions; they do not predict approval, underwriting, exact APR, insurance, taxes, or lender-specific rules.
