Loan Calculator

About This Calculator

The Loan Calculator estimates your monthly loan payment, total interest paid, and total repayment amount using the standard loan amortization formula. It helps you understand the cost of borrowing and plan your finances accordingly.

How It Works

The calculator uses the loan amortization formula to determine the fixed monthly payment based on the loan amount, interest rate, and loan term. It then calculates the total interest and repayment amount.

The Formula

M = P × [r(1 + r)^n] / [(1 + r)^n - 1]

Where:

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

Total Interest = (M × n) - P; Total Repayment = M × n

Example Calculation

For a $10,000 loan with 5% annual interest over 36 months:

Monthly Interest Rate = 5% / 12 = 0.004167
Monthly Payment ≈ $299.71
Total Interest ≈ $788.56
Total Repayment ≈ $10,788.56

Understanding Loan Calculations

A comprehensive guide to managing your loans

Taking out a loan is a common way to finance major purchases like a home, car, or education. The Loan Calculator helps you estimate your monthly payments, total interest, and repayment amount, enabling you to make informed borrowing decisions and manage your debt effectively.

Historical Context of Loan Calculations

The practice of lending dates back to ancient Mesopotamia, where interest-bearing loans were recorded on clay tablets. Modern loan calculations evolved with the development of compound interest in the Middle Ages and were formalized in the 19th century with the rise of banking systems. The introduction of amortization schedules in the 20th century allowed for precise repayment plans, and today’s calculators automate this process, providing instant insights into loan costs.

Historically, loan calculations required manual tables or complex arithmetic, but digital tools now ensure accuracy and accessibility for all borrowers.
