When to Use This Calculator

Use this calculator to:

  • Compare Loans: A loan with a lower interest rate might have a higher APR if the fees are high. APR is the best apples-to-apples comparison tool.
  • Understand True Cost: See how much extra you are really paying for a loan when fees are included.

Example Scenario

Formula Breakdown:
1. Add Interest & Fees: Sum up the total interest and any upfront fees.
2. Divide by Principal: Divide that sum by the initial loan amount.
3. Divide by Days: Divide the result by the total number of days in the loan term.
4. Annualize & Convert: Multiply by 365 (days in a year) and then by 100 to get the percentage.

Step-by-Step Example:
- Loan Principal: $160,000
- Total Interest: $25,000
- Fees: $5,000
- Term: 2 Years (730 Days)

Calculation:
- Total Cost: $25,000 + $5,000 = $30,000.
- Cost/Principal: $30,000 / $160,000 = 0.1875.
- Daily Rate: 0.1875 / 730 = 0.0002568...
- APR: 0.0002568... × 365 × 100 = 9.375%.
