Home Payment Calculator: Your Full Monthly Housing Cost

P&I vs. PITI: What's the Difference

Most mortgage calculators only show you principal and interest. That's the base payment that goes toward paying off your loan. But your actual monthly housing cost is higher, sometimes significantly higher, because it includes property taxes, homeowner's insurance, and HOA dues if your community has them.

PITI stands for Principal, Interest, Taxes, and Insurance. It's what lenders use when they calculate your debt-to-income ratio. If your PITI payment is too high relative to your income, you won't qualify for the loan even if the P&I alone looks manageable. For a deeper look at how that qualification process works, see how the mortgage approval process works.

What PMI Adds to Your Payment

PMI (private mortgage insurance) applies on conventional loans when your down payment is less than 20%. The cost varies by lender and credit profile, but a common estimate is around 0.85% of the loan amount annually. On a $315,000 loan that's roughly $223 per month added to your payment. PMI isn't permanent. It drops off once you hit 20% equity in most cases.

If you're trying to avoid PMI, you'll need to either put 20% down, choose an FHA loan (which has its own mortgage insurance structure), or look at lender-paid PMI options. Mortgage 101 breaks down how each loan type handles mortgage insurance.

Property Taxes in Florida

Florida's property tax rates differ by county and the calculator uses a percentage of the home price as a baseline estimate. Your real tax bill is set by the county appraiser based on the assessed value of the property, which may not match the purchase price. New construction and recently sold homes are often reassessed, which can push the tax bill up significantly. Factor in a buffer if you're budgeting for a new build.
