About Comparison Rate Calculator (Formula)

A Comparison Rate Calculator is a tool or formula used to calculate the comparison rate of a financial product, typically a loan or mortgage. The comparison rate represents the true cost of a loan, including both the interest rate and any associated fees and charges. This calculation is important for borrowers to make informed decisions about different loan options.

Formula for Comparison Rate Calculation:

The formula for calculating the comparison rate involves the nominal interest rate, the loan amount, the loan term, and any upfront fees or ongoing charges. The formula is designed to give borrowers a more accurate representation of the overall cost of borrowing.

Comparison Rate (%) = Nominal Interest Rate + (Total Fees and Charges / Loan Amount) * (365 / Loan Term in Days) * 100


  • Nominal Interest Rate: The stated interest rate on the loan.
  • Total Fees and Charges: The sum of all upfront fees and ongoing charges associated with the loan.
  • Loan Amount: The principal amount borrowed.
  • Loan Term in Days: The duration of the loan in days.

The formula considers the effective annual interest rate, incorporating both the interest rate and fees into the calculation.
