1. What is the Nerdwallet Affordability Calculator?

The Nerdwallet Affordability Calculator estimates how much house you can afford based on your annual income and selected affordability factor. It provides a quick assessment of your home-buying budget according to standard financial guidelines.

2. How Does the Calculator Work?

The calculator uses the Nerdwallet affordability formula:

Where:

• \( Income \) — Your annual gross income ($)
• \( Factor \) — Percentage of income you can spend on housing (28%-43%)

Explanation: The standard 28/36 rule suggests spending no more than 28% of gross income on housing expenses and no more than 36% on total debt. Some lenders may approve up to 43% in certain cases.

3. Importance of Affordability Calculation

Details: Calculating home affordability helps prevent being house-poor, ensures you can manage mortgage payments, and maintains financial stability after home purchase.

4. Using the Calculator

Tips: Enter your annual gross income before taxes and select an affordability factor based on your financial situation and risk tolerance. All values must be valid (income > 0).
