How APR is Calculated

Blends total finance charges and interest into an annualized percentage rate relative to the net principal proceeds.

Mathematical Formula
APR = ((Finance Charges + Total Interest) / (Principal × Term in Years)) × 100
Formula Variables & Logic

Finance charges include origination points and processing fees that increase the true cost of credit.

Worked Example: True APR on a Personal Loan
Sample Calculation
Scenario: A $10,000 personal loan at 8.0% for 3 years (36 months) with a $300 origination fee.
Step-by-step breakdown
  1. 1Interest at 8% = $1,281.00
  2. 2Total Finance Charges = $1,281 + $300 = $1,581.00
  3. 3Effective APR = 9.94%
Estimated Result
True loan APR is 9.94% (higher than stated 8.0% rate).

  • Loan term length (fees have a larger APR impact on shorter-term loans).
