When you borrow money—whether it’s a personal loan, mortgage, auto loan, or student loan—you’ll need to make regular repayments. Knowing exactly how much you’ll pay each month and the total cost of the loan is crucial for budgeting. A Repay Loan Calculator makes this simple by calculating monthly payments, total repayment amount, and interest paid over time.
Repay Loan Calculator
What is a Repay Loan Calculator?
A Repay Loan Calculator is an online tool that helps borrowers determine:
- Monthly loan repayment amount
- Total repayment over the loan term
- Total interest paid
- Amortization breakdown (optional, showing how each payment covers principal vs. interest)
It is useful for personal finance planning, comparing loan offers, and deciding on repayment strategies.
How Does the Calculator Work?
The calculator uses three main inputs:
- Loan Amount (Principal): The amount borrowed.
- Interest Rate: Annual percentage rate (APR).
- Loan Term: Number of months or years to repay.
Outputs:
- Monthly repayment amount
- Total repayment = monthly payment × number of months
- Total interest = total repayment – loan amount
Formula for Loan Repayment
The repayment formula (amortized loan formula) is:
M = P × [ r(1 + r)^n ÷ ((1 + r)^n – 1) ]
Where:
- M = Monthly payment
- P = Loan amount (principal)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (months)
Total Repayment = M × n
Total Interest = Total Repayment – P
Examples
Example 1: Personal Loan
- Loan amount = $10,000
- Interest rate = 6% annually
- Term = 3 years (36 months)
r = 0.06 ÷ 12 = 0.005
n = 36
M = 10,000 × [0.005(1.005)^36 ÷ ((1.005)^36 – 1)]
M ≈ $304.22
- Monthly payment = $304.22
- Total repayment = 304.22 × 36 = $10,951.92
- Total interest = 10,951.92 – 10,000 = $951.92
Example 2: Mortgage Loan
- Loan = $200,000
- Interest rate = 5%
- Term = 30 years (360 months)
Monthly payment ≈ $1,073.64
Total repayment ≈ $386,510.40
Total interest ≈ $186,510.40
