What Is a Loan Calculator?
A loan calculator is a financial tool that helps you estimate how much you will pay every month on a fixed-rate loan. It also shows the total amount paid over the full term and the total interest cost, helping you compare borrowing options before applying.
Loan Payment Formula
Monthly installment is calculated using the standard amortization formula:
M = P x ( r(1+r)n / ((1+r)n - 1) )
- M = Monthly payment
- P = Loan principal (amount borrowed)
- r = Monthly interest rate (annual rate / 12)
- n = Total number of monthly payments
Example Loan Calculation
- Loan Amount: $25,000
- Interest Rate: 8.5% per year
- Loan Term: 5 years
Estimated monthly payment: $512.91
Total repayment: $30,774.80
Total interest: $5,774.80
What Affects Your Loan Payment?
- Loan amount: Higher principal increases payment.
- Interest rate: Higher rates increase total borrowing cost.
- Loan term: Longer term lowers monthly EMI but raises total interest.
- Prepayments: Extra payments can reduce interest and shorten term.
