Formula Behind the Calculator
The formula used in most loan calculators, including the Credit Karma Loan Calculator, is based on the amortization formula:
Monthly Payment = P × [r(1 + r)^n] / [(1 + r)^n – 1]
Where:
- P = Loan amount (principal)
- r = Monthly interest rate (annual interest rate ÷ 12)
- n = Total number of monthly payments (loan term × 12)
This ensures each monthly payment covers both principal and interest, spread evenly over the loan term.
Example Calculation
Let’s say you want to borrow $20,000 for a car loan.
- Loan Amount = $20,000
- Interest Rate = 6% (0.06 annually, 0.005 monthly)
- Loan Term = 5 years (60 months)
Using the formula:
Monthly Payment = 20,000 × [0.005(1 + 0.005)^60] ÷ [(1 + 0.005)^60 – 1]
Monthly Payment ≈ $386.66
- Total Repayment = $386.66 × 60 = $23,199.60
- Total Interest Paid = $23,199.60 – $20,000 = $3,199.60
This breakdown shows how much you’ll actually pay beyond the borrowed amount.
