Formula Used in Loan Repayment Calculation
The calculator uses the standard amortization formula for monthly loan payments.
Monthly Payment Formula:
M=(1+r)n−1P×r×(1+r)n
Where:
- M = Monthly payment
- P = Loan principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of months (years × 12)
Supporting Calculations
Total Payment:
Total Payment=M×n
Total Interest:
Total Interest=Total Payment−P
Example Calculation
Let’s understand with a real example:
Loan Details:
- Loan Amount: $150,000
- Interest Rate: 5% per year
- Loan Term: 30 years
Step 1: Convert Values
- Monthly interest rate = 5 ÷ 12 ÷ 100 = 0.004167
- Total months = 30 × 12 = 360
Step 2: Monthly Payment
Using the formula, the monthly payment is approximately:
👉 $805.23 per month
Step 3: Total Payment
805.23 × 360 = $289,882.80
Step 4: Total Interest
289,882.80 − 150,000 = $139,882.80

Factors That Affect Your Loan Repayment
