Loan Calculation Formula Explained
This calculator uses the standard loan amortization formula used by banks worldwide.
Monthly Payment Formula
M=1−(1+r)−nP⋅r
Where:
- M = Monthly payment
- P = Loan principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
Monthly Interest Rate Conversion
r=12×100R
Where:
- R = Annual interest rate (%)
Total Payment Formula
Total Payment=M×n
Total Interest Formula
Total Interest=Total Payment−P
Example Calculation (Real Life Scenario)
Let’s understand how this calculator works with a real example.
Given:
- Loan Amount = $400,000
- Interest Rate = 6% per year
- Loan Term = 30 years
Step 1: Monthly Interest Rate
6% ÷ 12 = 0.5% per month
0.5 ÷ 100 = 0.005
Step 2: Total Payments
30 × 12 = 360 months
Step 3: Monthly Payment
Using formula:
Monthly payment ≈ $2,398.20
Step 4: Total Payment
$2,398.20 × 360 = $863,352
Step 5: Total Interest
$863,352 − $400,000 = $463,352
Final Summary:
- Monthly Payment: $2,398.20
- Total Payment: $863,352
- Total Interest: $463,352

Even a small difference in interest rate can change your total payment by thousands of dollars.
