Loan Interest Savings
Compare total interest between two loan term lengths.
About Loan Interest Savings
Both terms are priced with the monthly payment formula, and the interest saved is the difference in total interest paid. A shorter term raises the payment but demolishes interest, and seeing both numbers side by side clarifies the trade-off.
