How do I calculate monthly payments on a loan?

How to Calculate Monthly Loan Payments

Understanding how to calculate monthly loan payments is crucial for financial planning and budgeting. Whether you’re considering a mortgage, car loan, or personal loan, this step-by-step guide will help you determine the amount you’ll pay each month.

Step 1: Determine Your Monthly Interest Rate

Start by dividing your annual interest rate by 12. For instance, if your loan carries a 6% annual interest rate, your monthly interest rate would be 6% / 12 = 0.005.

Step 2: Calculate the Interest Paid Over the Loan Term

Next, multiply the loan amount by your monthly interest rate. This will give you the total interest you’ll pay over the life of the loan. For example, if you borrowed $10,000 at 6% annual interest for 5 years, the total interest would be:

$10,000 x 0.005 x (5 x 12) = $3,000

Step 3: Calculate Your Monthly Payment

Finally, divide the loan amount by the total interest paid over the loan term. This will provide you with your monthly payment amount. In our example:

$10,000 / $3,000 = $208.33

Therefore, your monthly payment for a $10,000 loan at 6% annual interest for 5 years would be $208.33.

Example Calculations

Mortgage:

• Loan amount: $250,000
• Annual interest rate: 4%
• Loan term: 30 years

Monthly interest rate: 4% / 12 = 0.0033
Total interest: $250,000 x 0.0033 x (30 x 12) = $264,000
Monthly payment: $250,000 / $264,000 = $947.01

Car Loan:

• Loan amount: $20,000
• Annual interest rate: 5%
• Loan term: 4 years

Monthly interest rate: 5% / 12 = 0.00417
Total interest: $20,000 x 0.00417 x (4 x 12) = $4,012.80
Monthly payment: $20,000 / $4,012.80 = $498.34

Personal Loan:

• Loan amount: $5,000
• Annual interest rate: 10%
• Loan term: 2 years

Monthly interest rate: 10% / 12 = 0.0083
Total interest: $5,000 x 0.0083 x (2 x 12) = $1,000
Monthly payment: $5,000 / $1,000 = $500
