Residual Income + Cash Buffer Analysis
Enter how much money you make each month before taxes. The calculator will figure out what you keep after taxes.
Put in things like car payments, credit cards, groceries, fun stuff, and money you want to save. The calculator helps estimate these.
Use the slider or type in how much the house costs. Also tell us how much money you're putting down and what interest rate the bank offers.
Enter yearly property taxes, insurance, and monthly costs like HOA fees and utilities. These are the extras you pay besides the mortgage.
Enter how much money you have saved up. This helps the calculator see if you'll have enough left over after buying the house.
Look at the right side to see three prices: Comfort (safe and easy), Stretch (a bit tight but okay), and your current choice's grade. Green means great, yellow means careful, red means too much!
💡 Quick Tip: The calculator tests "what if" scenarios - like what happens if interest rates go up or your income goes down. This helps you pick a home price that's safe even if things change!
