How to Use This Calculator

- Enter your monthly expenses including rent, utilities, and other obligations.
- Select your desired loan term in years.
- Enter your down payment amount if applicable.
- Click Calculate to see your estimated monthly payment.
The calculator will show you how much you can afford based on the standard 28/36 rule, which recommends that your housing payment should not exceed 28% of your gross monthly income and your total debt payments should not exceed 36% of your gross monthly income.
Formula Explained
The affordability calculator auto uses the following formula to estimate your monthly payment:
Monthly Payment Formula
Monthly Payment = (Loan Amount × (Interest Rate / 12)) / (1 - (1 + (Interest Rate / 12))- (Loan Term × 12))
Where:
- Loan Amount = Purchase Price - Down Payment
- Interest Rate = Annual interest rate for the loan
- Loan Term = Length of the loan in years
The calculator assumes a standard interest rate of 5% if you don't provide one. You can adjust this rate based on current market conditions.
Worked Example
Let's say you want to buy a car with a purchase price of $25,000, a down payment of $5,000, and a loan term of 5 years. Using an interest rate of 5%, the calculation would be:
Example Calculation
Loan Amount = $25,000 - $5,000 = $20,000
Monthly Interest Rate = 5% / 12 = 0.4167%
Number of Payments = 5 × 12 = 60
Monthly Payment = ($20,000 × 0.004167) / (1 - (1 + 0.004167)-60) ≈ $362.50
Based on this example, your estimated monthly payment would be $362.50.
Comparison Table
Here's a comparison of monthly payments for different loan terms and interest rates:
| Loan Term (Years) | Interest Rate (5%) | Interest Rate (4%) | Interest Rate (6%) |
|---|---|---|---|
| 3 | $525.00 | $500.00 | $550.00 |
| 4 | $450.00 | $430.00 | $470.00 |
| 5 | $390.00 | $375.00 | $405.00 |
| 6 | $345.00 | $330.00 | $360.00 |
| 7 | $310.00 | $295.00 | $325.00 |
This table shows how different loan terms and interest rates affect your monthly payment. Shorter loan terms generally result in higher monthly payments, while lower interest rates reduce your monthly obligation.
