Loan Calculation Formula Explained
The calculator uses a standard amortization formula used by banks worldwide.
Monthly Payment Formula:
M=(1+r)n−1P⋅r⋅(1+r)n
Where:
- M = Monthly payment
- P = Loan principal ($20,000)
- r = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
- n = Total number of months (Years × 12)
Total Payment Formula:
Total Payment = Monthly Payment × Number of Months
Total Interest Formula:
Total Interest = Total Payment − Principal
Example Calculation
Let’s understand with a real-world example.
Scenario:
- Loan Amount = $20,000
- Interest Rate = 8% per year
- Loan Term = 5 years
Step 1: Convert Values
- Monthly interest rate = 8 ÷ 12 ÷ 100 = 0.00667
- Months = 5 × 12 = 60
Step 2: Results
| Metric | Value (Approx.) |
|---|---|
| Monthly Payment | $405.53 |
| Total Payment | $24,331.80 |
| Total Interest | $4,331.80 |
Interpretation:
- You pay about $405 per month
- Total repayment is over $24,000
- Interest cost is around $4,300
