Loan Comparison Calculator

Two loan offers can look similar until you line up the numbers. This free calculator puts competing loans side by side — monthly payment, total interest, fees, and the true cost — so the cheaper deal is obvious at a glance.

How the loan comparison calculator works

Enter each offer's loan amount, interest rate, term length, and any fees — origination charges, closing costs, or points. The calculator works out the monthly payment and total repayment for each, then ranks the offers by true cost.

A lower rate isn't always the winner. Fees and longer terms can quietly inflate the total you repay, which is why comparing monthly payment alone can mislead you.

Worked example: lower rate vs lower payment

Borrow $12,000 and compare two offers: Offer A charges 9% over 36 months with no fee; Offer B charges 7.5% over 60 months with a 3% origination fee. A costs less overall; B has the smaller monthly payment.

This is the classic trade-off: a shorter term at a higher rate can still beat a longer term at a lower one. Choose based on whether total cost or monthly comfort matters more.

What to watch out for

Watch for fees that aren't in the advertised rate — origination, application, or prepayment penalties. A loan with no fee but a slightly higher rate often beats a low rate loaded with charges.

Also confirm whether the rate is fixed or variable. A variable rate can rise after the first year, making today's comparison outdated. Treat results as estimates, not financial advice.

Frequently asked questions

What matters more: rate or monthly payment?

Both matter, but total cost matters most. A low monthly payment spread over more years usually means paying much more interest overall. Compare the total repayment first, then check whether the monthly payment fits your budget comfortably.

Should I compare APR or interest rate?

Compare APR — it folds most fees into a single yearly figure, so offers with different fee structures can be weighed fairly. The plain interest rate ignores fees, which is exactly how a cheap rate can hide an expensive loan.

How many offers should I compare?

Three to five serious offers is the sweet spot. Fewer and you might miss a better deal; more and the details blur together. Get at least one quote from a bank, one from a credit union, and one from an online lender.

Do loan comparisons affect my credit score?

Shopping around is expected — multiple applications for the same loan type within a 14 to 45 day window usually count as a single inquiry. Use the calculator to narrow your list first, then apply to your finalists in one focused round.
