Loan comparison

Put two loan offers side by side and see which really costs less.

Offer A

Offer B

ComparisonOffer AOffer B
Monthly payment$300.57$285.51
Total paid$18,034.15$20,556.81
Total interest$3,034.15$5,556.81
Offer A costs $2,522.65 less in interest over the life of the loan. A lower monthly payment often means a longer term — and more interest overall. Look at the total, not just the monthly.
How this is calculated

Each offer uses the standard fixed-rate amortized payment formula: payment = P × i ÷ (1 − (1 + i)⁻ⁿ), where P is the amount borrowed, i is the monthly rate (APR ÷ 12), and n is the number of months.

Total paid is the monthly payment times the number of months. Total interest is total paid minus what you borrowed — the real price of the loan. Two loans can have similar monthly payments but very different total costs.
