Formula Used

The monthly payment for a personal loan is calculated using the following formula:

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

Where:

P = Principal loan amount ($15,000)
r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
n = Number of payments (loan term in years × 12)

This formula accounts for the interest charged on the outstanding loan balance each month, which is why the monthly payment increases over time as you pay down the principal.

Worked Example

Let's calculate the monthly payment for a $15,000 loan at 5% annual interest over 5 years:

Convert annual interest rate to monthly: 5% ÷ 12 = 0.4167% or 0.004167
Calculate number of payments: 5 years × 12 = 60 months
Plug values into formula:

Monthly Payment = $15,000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)
Calculate the result: $273.64 per month

This means you would pay $273.64 each month for 60 months, with a total interest charge of $1,824.00, bringing your total repayment to $16,824.00.

Frequently Asked Questions

What is a personal loan?

A personal loan is an unsecured loan that you can use for any purpose, such as debt consolidation, home improvement, or medical expenses. Personal loans typically have fixed interest rates and fixed repayment terms.

How do interest rates affect my monthly payment?

Higher interest rates increase your monthly payment because more of each payment goes toward interest rather than principal. Lower interest rates mean you pay less each month and pay off the loan faster.

What happens if I make extra payments?

Making extra payments reduces the principal balance faster, which means you'll pay less in total interest. The calculator shows how your payment changes if you adjust the loan term or interest rate.

Can I refinance my personal loan?

Yes, you can refinance a personal loan to get a better interest rate or change the loan term. Refinancing typically requires good credit and may have fees, so it's important to compare offers carefully.
