Personal Loan Calculator Formula & How It Works
- Personal loans: $1,000–$100,000 typically
- Terms: 1–7 years
- Rates: 6–36% depending on credit
- Usually no collateral required (unsecured)
Personal loans use the standard amortization formula. Because they are unsecured, rates are higher than mortgage or auto loans. Comparing APR (not just rate) across lenders accounts for origination fees, which can be 1–8% of the loan amount.
