The loan repayment calculator below is for loans that pay back a fixed amount periodically. Most personal loans (mortgage, auto, student loan, etc.) and small business loan belong to this category. For other payback options, you can use our loan calculator. Some loans have fees to be deducted from Loan. Such fees are equivalent to pay upfront fees. If your loan has fees (origination fee, points, etc.), the calculator below gives out the real after-fee interest rate for loan comparison.
