The Personal Loan Formula

Personal loans use standard amortization: M = P × [r(1+r)^n] / [(1+r)^n – 1] where P is principal, r is monthly interest rate, and n is total payments. Unlike credit cards, personal loans have fixed payments that pay off the loan by a specific date. For a $15,000 personal loan at 10% APR for 48 months, your monthly payment would be approximately $380, with total interest of about $3,280.

Fixed Rate vs Variable Rate

Most personal loans have fixed rates, meaning your payment stays the same throughout the loan term. This makes budgeting predictable. Variable rate loans may start lower but can increase over time, making them riskier for longer terms. Fixed rates are especially valuable when interest rates are expected to rise. Lock in today's rate and know exactly what you'll pay each month.

Origination Fees and True Cost

Many personal loans charge origination fees (1-8% of loan amount). A $10,000 loan with 5% origination fee means you receive $9,500 but repay $10,000. This effectively increases your interest rate. Always calculate the APR including fees to compare loans accurately.

Example: Home Improvement Project

  • -Mark needs $20,000 for a kitchen renovation and qualifies for 11% APR over 60 months.
  • -Input: $20,000 loan, 11% APR, 60-month term
  • -Convert to: Monthly payment and total cost
  • -Result: $435/month, $26,100 total paid ($6,100 in interest)
  • -The fixed payment fits Mark's budget, and the home improvement adds value to his property.

Example: Medical Expenses

  • -Sarah has $8,000 in medical bills and found a personal loan at 8% APR for 24 months.
  • -Input: $8,000 loan, 8% APR, 24-month term
  • -Convert to: Monthly payment and total interest
  • -Result: $362/month, $688 total interest
  • -A short-term personal loan costs far less than medical debt going to collections or using high-interest credit cards.
