Mortgage Calculator.
The full monthly payment - principal, interest, taxes, insurance, HOA, and mortgage insurance - itemized honestly. Then the same math in reverse: what a housing budget actually supports.
Your home
Enter your figures - the payment updates as you type.
How much home can a budget support?
The 28/36 defaults are a common convention - programs vary, and a lender's real answer depends on your full profile.
PITI is principal & interest (standard amortization at your entered rate and term) plus taxes/12, insurance/12, HOA, and mortgage insurance entered as an annual percent of the loan - we never pre-fill an MI rate. The affordability view applies your housing and total-debt ratios to gross income, subtracts your tax/insurance/HOA estimate, and inverts the amortization formula; it is an illustration of arithmetic, not a qualification. Rates are your estimates - we deliberately publish none. Estimates are educational, not an approval, offer, rate quote or guarantee. See how these figures are calculated.

Have a specialist run it for real.
A specialist reads your scenario against actual program guidelines and replies personally within one business day - which paths fit, what they'd really cost, and what to line up next.
Before you run the numbers
Why does the payment differ from other calculators?
Most calculators show principal and interest only. This one shows the payment you'll actually write each month - taxes, insurance, HOA, and mortgage insurance included - because that's the number a household budgets around, and the one lenders qualify against.
What are the 28/36 ratios?
A common underwriting convention: housing costs within about 28% of gross monthly income, and all debt payments within about 36%. Real programs vary - some flex well beyond these numbers with strong compensating factors - which is why the sliders are yours to move and why the output is labeled an illustration, not a qualification.
Why don't you pre-fill a rate?
Rates move daily and vary with your profile - a pre-filled number would be marketing pretending to be math. Enter a rate you consider realistic (or a couple of scenarios); the arithmetic is exact for whatever you enter, and a specialist can tell you what's realistic for your file today.
