When planning to take a loan—whether for a home, car, education, or personal needs—one of the most important things to understand is how much you will actually pay back over time. Many borrowers only focus on the loan amount they receive, but the real cost includes interest and total repayment, which can significantly increase the overall expense.

Loan Calculation Formula Explained
The calculator uses the standard amortization formula used by banks and financial institutions worldwide.
Monthly Payment Formula:
M=1−(1+r)−nP×r
Where:
- M = Monthly payment
- P = Loan principal (amount borrowed)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (loan term in months)
Understanding the Formula
- Convert Annual Interest to Monthly Rate
Annual interest is divided by 12 to get monthly interest. - Convert Years into Months
Loan term is multiplied by 12. - Apply Compound Interest Logic
The formula spreads interest across all monthly payments. - Final Output
Gives a fixed monthly installment that includes both principal and interest.
Example Calculation
Let’s understand with a real-life example:
- Loan Amount: $20,000
- Interest Rate: 6% per year
- Loan Term: 5 years
Step-by-step result:
- Monthly Interest Rate = 0.06 ÷ 12 = 0.005
- Total Months = 5 × 12 = 60
After applying the formula:
- Monthly Payment: $386.66 (approx.)
- Total Payment: $23,199.60
- Total Interest: $3,199.60
What the Results Mean
1. Monthly Payment
This is the fixed amount you must pay every month until the loan ends.
