What is Loan Calculator?

A loan is a sum of money borrowed from a lender that you repay over time with interest. Loans can be secured (backed by collateral) or unsecured (based on creditworthiness).

How It Works

When you take out a loan, you receive a lump sum and agree to repay it in regular installments over a set term. Each payment covers part of the principal and the interest accrued since your last payment.

The Formula

M = P × [r(1+r)^n] / [(1+r)^n - 1]

M = Monthly payment, P = Loan principal, r = Monthly interest rate (annual rate / 12), n = Total number of payments (loan term in months)

Examples

Example: $20,000 Personal Loan at 7.5%

A $20,000 personal loan with 7.5% APR for 5 years (60 months)

With a $20,000 loan at 7.5% APR for 60 months, the monthly payment is $400.76. You'll pay $4,045.62 in total interest over the life of the loan.

Frequently Asked Questions

What is the difference between APR and interest rate?
The interest rate is the cost of borrowing the principal, while APR (Annual Percentage Rate) includes both the interest rate and any fees charged by the lender. APR gives you a more complete picture of the loan's cost.
How does my credit score affect my loan rate?
Your credit score is one of the biggest factors lenders use to determine your interest rate. Higher scores generally qualify for lower rates. A difference of even 1-2% can mean thousands of dollars in savings over the life of a loan.
Should I choose a shorter or longer loan term?
Shorter terms have higher monthly payments but less total interest. Longer terms have lower monthly payments but cost more in interest. Choose based on your monthly budget and how quickly you want to be debt-free.
Can I pay off my loan early?
Most loans allow early payoff, but some have prepayment penalties. Check your loan agreement before making extra payments. If there's no penalty, paying extra toward principal can save you significant interest.
