What the Loan Comparison calculator works out

The Loan Comparison Calculator is a free, embeddable calculator from CalcFunnel. Compare two loan options side by side — payment and lifetime interest.

You enter 5 inputs: loan amount, option A rate (%), option A term (years), option B rate (%) and option B term (years).

It returns lower payment, option A payment, option B payment, option A total interest, option B total interest and interest saved with lower-interest option.

Built for lenders, credit unions and borrowers. Embedding it on your own website is included on the Free plan (free forever for up to 5 calculators on one domain), as part of the Loans & Amortization category.
