How to Calculate Loan Payments

Quick Answer: Loan payments depend on the principal amount, interest rate, and loan term. For a $100,000 loan at 6.5% for 5 years, your monthly payment would be approximately $1,956.

The payment calculation uses compound interest and ensures that your loan is fully paid off by the end of the term. More frequent payments (bi-weekly or weekly) can reduce total interest costs.

Loan Payment Formula

Understanding how loan payments are calculated

The Standard Loan Payment Formula

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

Where:

  • M = Monthly payment
  • P = Principal loan amount
  • r = Periodic interest rate (annual rate ÷ payments per year)
  • n = Total number of payments

Step-by-Step Example:

Loan Amount: $100,000

Annual Interest Rate: 6.5%

Loan Term: 5 years (60 months)

Step 1: Convert annual rate to monthly rate

r = 6.5% ÷ 12 = 0.5417% = 0.005417

Step 2: Calculate total number of payments

n = 5 years × 12 months = 60 payments

Step 3: Apply the formula

M = $100,000 × [0.005417 × (1.005417)^60] / [(1.005417)^60 - 1]

M = $100,000 × 0.019561 = $1,956.10

Frequently Asked Questions

Common questions about loan payment calculations

How do I calculate loan payments?

Loan payments are calculated using the formula: M = P [ r(1 + r)^n ] / [ (1 + r)^n – 1 ], where M is the payment, P is the principal, r is the periodic interest rate, and n is the number of payments. This calculator handles monthly, bi-weekly, and weekly payment frequencies.

What's the difference between payment frequencies?

Monthly payments are made 12 times per year, bi-weekly payments are made 26 times per year (every two weeks), and weekly payments are made 52 times per year. More frequent payments can reduce total interest paid and shorten the loan term.

Should I make bi-weekly payments instead of monthly?

Bi-weekly payments can save you money on interest and pay off your loan faster. Since you make 26 bi-weekly payments per year (equivalent to 13 monthly payments), you pay down the principal faster, reducing total interest costs.

Can I use this calculator for any type of loan?

Yes, this payment calculator works for any installment loan including personal loans, student loans, auto loans, mortgages, and business loans. Simply enter the loan amount, interest rate, and term to get your payment amount.

How accurate are the payment calculations?

The calculations use standard financial formulas and are highly accurate for installment loans with fixed interest rates. For variable rate loans or loans with fees, consult with your lender for exact payment amounts.

What factors affect my loan payment?

Your loan payment is affected by the principal amount (loan size), interest rate, loan term (length), and payment frequency. Higher loan amounts and interest rates increase payments, while longer terms and more frequent payments can decrease individual payment amounts.

Can I pay off my loan early?

Most loans allow early payoff, which can save you money on interest. Check your loan agreement for any prepayment penalties. Making extra principal payments or switching to more frequent payment schedules can help you pay off loans faster.

How do I reduce my loan payments?

You can reduce loan payments by: extending the loan term (though this increases total interest), refinancing to a lower interest rate, making a larger down payment, or improving your credit score to qualify for better rates.

Smart Payment Strategies

To Reduce Total Interest

  • • Make bi-weekly instead of monthly payments
  • • Add extra principal to each payment
  • • Choose shorter loan terms when possible
  • • Refinance to lower interest rates
  • • Make one extra payment per year

To Lower Monthly Payments

  • • Extend the loan term (increases total interest)
  • • Improve credit score before applying
  • • Shop around for better interest rates
  • • Consider a co-signer for better rates
  • • Make a larger down payment
