What is the Money Guy House Calculator?
The money guy house calculator is a financial planning tool designed around the conservative home-buying principles advocated by Brian Preston and Bo Hanson of “The Money Guy Show”. Unlike calculators that tell you the absolute maximum a bank will lend you, this calculator determines an affordable home price that aligns with long-term wealth-building. The core principle is to prevent you from becoming “house poor,” where an excessive amount of your income is consumed by housing costs, leaving little for saving and investing.
This calculator is for prospective homebuyers who want to make a smart financial decision, not just an emotional one. It’s for those who follow or are interested in The Money Guy’s Financial Order of Operations and want to ensure their largest purchase doesn’t derail their journey to financial independence.
The Money Guy House Formula and Explanation
The Money Guy approach doesn’t use a single, simple formula. Instead, it’s a set of three constraining rules that work together to define a “safe” home price. The most affordable home price is the one that satisfies all three conditions.
- The 25% Rule: Your total monthly housing payment (PITI: Principal, Interest, Taxes, and Insurance) should not exceed 25% of your gross monthly income.
- The 3x Income Rule: The total price of the home should ideally not exceed 3 times your gross annual income. This is a general guardrail to keep the overall debt load manageable.
- The 20% Down Payment Rule: You should aim to have a 20% down payment to avoid Private Mortgage Insurance (PMI), which adds to your monthly cost without building equity.
Our calculator finds the maximum home price where the PITI remains at or below 25% of your gross monthly income, while also respecting the 3x income cap.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| P | Principal & Interest | $/month | Varies based on loan |
| T | Property Taxes | $/month | 0.5% – 2.5% of home value annually |
| I | Homeowner’s Insurance | $/month | $50 – $200 per month |
| GMI | Gross Monthly Income | $/month | Varies |
Practical Examples
Example 1: The Starting Professional
- Inputs: Gross Annual Income: $80,000, Down Payment: $30,000, Interest Rate: 6.5%
- Calculations:
- Max Monthly Payment (25% of $6,667): $1,667
- Income Cap (3 x $80,000): $240,000
- Results: The calculator would determine a maximum affordable home price of approximately $240,000. The monthly payment on this home would be within the $1,667 limit, and the price is at the 3x income cap. The required 20% down payment would be $48,000, so this buyer would need to save more or accept paying PMI.
Example 2: The Established Household
- Inputs: Gross Annual Income: $150,000, Down Payment: $100,000, Interest Rate: 6.5%
- Calculations:
- Max Monthly Payment (25% of $12,500): $3,125
- Income Cap (3 x $150,000): $450,000
- Results: In this case, the 25% payment rule is the main constraint. A home price of approximately $445,000 (with a $100,000 down payment) results in a monthly PITI near the $3,125 limit. This is below the $450,000 income cap, making it the more conservative and appropriate choice. The buyer easily covers the 20% down payment.

How to Use This Money Guy House Calculator
Using this calculator is a straightforward process to get a conservative and realistic home budget.
- Enter Your Gross Annual Income: Input your total household income before any taxes or deductions are taken out.
- Input Your Down Payment: Enter the total amount of cash you have saved specifically for a down payment.
- Set the Interest Rate: Adjust this to reflect current market rates for a mortgage. Even a small change can significantly impact affordability.
- Choose Loan Term: While 30 years is standard, a 15 or 20-year term builds equity much faster, a key Money Guy principle.
- Estimate Taxes and Insurance: Use the default percentages or adjust them if you know the typical rates for your area. These are crucial for an accurate PITI calculation.
- Analyze the Results: The primary result is your maximum affordable home price. Pay close attention to the intermediate values to understand your constraints—is your limit based on the monthly payment or your total income? Use the chart to visually see how close your estimated payment is to the 25% ceiling.
Key Factors That Affect Housing Affordability
Several factors beyond simple income can influence how much house you can afford according to the money guy house calculator principles.
- Interest Rates: A higher interest rate means more of your payment goes to the bank and less towards your principal. This directly reduces the home price you can afford under the 25% rule.
- Down Payment Amount: A larger down payment reduces the loan size, lowering your monthly principal and interest payment. It’s also the key to avoiding PMI.
- Loan Term: A shorter loan term (e.g., 15 years) has higher monthly payments but saves you a massive amount of interest over the life of the loan. This may reduce the price of the home you can buy now but accelerates wealth-building.
- Property Taxes: High-tax areas can dramatically increase your monthly PITI, significantly lowering the home price you can afford even with a high income.
- Homeowner’s Insurance: Costs can vary based on location (e.g., flood zones, hurricane areas), the age of the home, and other risk factors.
- Existing Debt: While not a direct input in this calculator, The Money Guy’s philosophy assumes you are following the Financial Order of Operations and have already paid off high-interest debt before considering a home purchase.
Frequently Asked Questions (FAQ)
1. Why 25% of GROSS income and not net income?
The Money Guy team uses gross (pre-tax) income as the standard for their 25% rule. It provides a consistent baseline for comparison. Using net (after-tax) income would be even more conservative but can vary widely based on individual tax situations. Sticking to 25% of gross is the established guideline for a healthy housing budget.
2. What is PITI?
PITI stands for Principal, Interest, Taxes, and Insurance. It represents the total monthly cost of your housing payment, and it’s the number that should stay below 25% of your gross monthly income.
3. What if I can’t afford a house in my area with these rules?
This is a common challenge in high-cost-of-living areas. The rule is a guideline for financial health. If you can’t meet it, it suggests that buying right now might make you “house poor.” The answer might be to save for a larger down payment, work on increasing your income, or consider moving to a more affordable area. Check out our resources on Saving Money for tips.
4. Should I include HOA fees in the 25% calculation?
Yes, absolutely. If a property has a Homeowners Association (HOA) fee, you should add it to your PITI to get your true total housing cost. Our calculator has an advanced option to include this.
5. Why is there a 3x income rule?
The 3x income rule acts as a ceiling to prevent taking on an excessively large mortgage, even if low interest rates make the monthly payment seem manageable. It’s a guardrail against lifestyle inflation and taking on too much debt relative to your earning power.
6. What about maintenance and utilities?
The 25% rule specifically covers PITI. You should budget for maintenance (a common rule of thumb is 1-2% of the home’s value per year) and utilities separately. Not including these in the 25% rule prevents the guidelines from being impossibly strict for most people.
7. Is it ever okay to go over 25%?
The Money Guy team acknowledges that in some very high-cost areas, you might need to stretch to 28-30%, but it should be done with extreme caution and a clear understanding that it will slow down your other financial goals. It is generally not recommended.
8. Where does buying a house fit in the Financial Order of Operations?
Home buying is typically considered around Step 7 (Hyper-Accumulation) or Step 8 (Prepaid Future Expenses). It should only come after you have a fully funded emergency fund, are investing at least 20-25% towards retirement, and have no high-interest debt.
