Key takeaways
- A $15,000 principal at 7.49% APR for 5 years is about $300 per month before fees (illustrative).
- Raising APR by ~2 points usually hurts more than shortening the term by a year on mid-size personal loans—run both levers in the full calculator.
- Total interest is principal × (payment schedule − 1). Escrow, insurance, and origination fees are not in the simple amortization math.
- Use this page for planning anchors; use a lender quote APR for decisions.

Common mistakes: ignoring origination fees, treating interest-only quotes as amortizing payments, and forgetting insurance/taxes on secured loans. Confirm material decisions with a licensed lender or advisor.
