Formulas Used in Loan Payback Calculation
The Payback Loan Calculator generally uses the standard amortization formula:
- Monthly Payment Formula
M = P × r × (1 + r)ⁿ ÷ [(1 + r)ⁿ − 1]
Where:
M = Monthly payment
P = Principal loan amount
r = Monthly interest rate (APR ÷ 12)
n = Total number of payments (months)
- Total Interest Paid
Total Interest = (M × n) − P
- Remaining Balance (Amortization)
Balance after k payments = P × (1 + r)ᵏ − M × [(1 + r)ᵏ − 1] ÷ r
This formula allows tracking of outstanding balances throughout the loan term.
Step-by-Step Example
Example 1: Personal Loan
Loan amount = $15,000
Interest rate = 5% APR
Term = 3 years (36 months)
Step 1: Convert annual rate to monthly:
r = 5 ÷ 12 ÷ 100 = 0.004167
Step 2: Calculate monthly payment:
M = 15,000 × 0.004167 × (1 + 0.004167)³⁶ ÷ [(1 + 0.004167)³⁶ − 1]
M ≈ $449.22
Step 3: Total interest paid:
Total Interest = (449.22 × 36) − 15,000 ≈ $1,171.92
✅ Result: Monthly payment = $449.22, Total interest = $1,171.92
Example 2: Loan with Extra Payments
Loan amount = $10,000
Interest rate = 6% APR
Term = 5 years (60 months)
Extra monthly payment = $50
Using the calculator, you can see:
Reduced total interest
Shortened repayment period
