Money Lending Calculator

Use this money lending calculator to determine loan payments, interest rates, and repayment schedules. Whether you're evaluating personal loans, mortgages, or business financing, this tool provides accurate financial projections to help you make informed decisions.

How to Use This Calculator

Enter the loan amount, interest rate, and loan term to calculate monthly payments and total interest. The calculator uses standard amortization formulas to provide accurate projections.

Note: This calculator assumes fixed interest rates and regular monthly payments. Variable rates or irregular payments may require different calculations.

Formula Used

The calculator uses the standard loan payment formula:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
n = Number of payments (loan term in years × 12)

Total interest paid is calculated by subtracting the principal from the total of all monthly payments.

Worked Example

For a $200,000 loan at 4.5% annual interest for 30 years:

Monthly interest rate = 4.5% ÷ 12 ÷ 100 = 0.00375
Number of payments = 30 × 12 = 360
Monthly payment = $200,000 × (0.00375(1 + 0.00375)^360) / ((1 + 0.00375)^360 - 1) ≈ $1,199.44
Total paid = $1,199.44 × 360 ≈ $431,798.40
Total interest = $431,798.40 - $200,000 = $231,798.40

Interpreting Results

The calculator provides several key metrics:

Monthly Payment: The amount you'll pay each month
Total Interest: The total amount paid in interest over the loan term
Total Cost: The principal plus total interest
Amortization Schedule: A chart showing how much of each payment goes toward principal and interest

Use these results to compare different loan options, evaluate your budget, and understand the true cost of borrowing.
