How to read your result
The calculator gives you a home price range built from three inputs.
Your income sets the ceiling. Lenders generally want your total monthly debt, including the new mortgage, to stay under about 43% of your gross monthly income. Some programs go higher.
Your existing debts lower that ceiling. Every $100 in monthly payments elsewhere is roughly $100 less you can put toward a house payment.
Your down payment shifts the whole range up. More cash in means a smaller loan for the same price, or a higher price for the same loan.
The result is usually shown as a comfortable range and a stretch range. The comfortable number assumes your housing cost stays near 28% of gross income. The stretch number pushes toward the lender's maximum. Both are real options. The comfortable one leaves room for the things a spreadsheet doesn't show: a new roof, a job change, a kid.
What "afford" really means
A lender approves you based on math. You live in the house based on everything else. Before you settle on a number, ask:
Will the monthly payment still feel fine after utilities, maintenance (budget about 1% of the home's value per year), and HOA dues?
Do you have three to six months of expenses saved after closing?
Is your income stable enough to carry this payment through a rough year?
If the answer to any of those is a hesitant "probably," the comfortable range is your number.
A quick example
Household gross income: $110,000 per year, or about $9,167 per month. Monthly debts: $600. Down payment saved: $40,000.
At a 28% front-end target, your comfortable housing payment is around $2,570. At a 43% back-end limit minus your $600 in other debts, the stretch payment is closer to $3,340.
With today's typical rates, taxes, and insurance, that puts your comfortable price somewhere around $360,000 to $380,000, and your stretch price closer to $450,000. The calculator does this math with your actual inputs and a current rate estimate.
