Reviewed by Calculator Editorial Team

The 75-15-10 loan calculator helps you determine your monthly payments, interest costs, and loan amortization schedule using the 75-15-10 rule. This method divides your loan into three parts: 75% for the principal, 15% for interest, and 10% for fees and other costs.

What is a 75-15-10 Loan?

The 75-15-10 rule is a simple method for estimating loan payments and costs. It divides the total loan amount into three components:

  • 75%: Principal amount you need to borrow
  • 15%: Interest cost over the life of the loan
  • 10%: Fees and other costs associated with the loan

This rule provides a quick way to estimate your monthly payments without needing complex financial calculations. It's particularly useful for understanding the total cost of borrowing before applying for a loan.

How the 75-15-10 Rule Works

The 75-15-10 rule works by dividing the total loan amount into three parts:

Principal (75%): The amount you need to borrow

Interest (15%): Estimated interest cost over the loan term

Fees (10%): Estimated fees and other costs

The monthly payment is then calculated by dividing the total loan amount by the number of payments (loan term in months).

Monthly Payment = Total Loan Amount / (Loan Term × 12)

This method provides a quick estimate of what your monthly payments might be, helping you budget for your loan.

Example Calculation

Let's say you need a $50,000 loan with a 5-year term:

Component Amount
Principal (75%) $37,500
Interest (15%) $7,500
Fees (10%) $5,000
Total Loan Amount $50,000

The monthly payment would be:

Monthly Payment = $50,000 / (5 × 12) = $833.33

This example shows how the 75-15-10 rule helps you quickly estimate your monthly payments and understand the total cost of borrowing.
