Mortgage Payment Calculator.
The real monthly number: principal, interest, county property tax, insurance, PMI, and HOA/CDD.
Most payment calculators stop at principal and interest. In Florida the taxes, insurance, and community fees are where budgets break. This one applies your county's actual FY2025-26 millage with homestead exemption logic, estimates when PMI drops off, and totals the payment you would actually write a check for.
Your numbers
The home
County tax uses FY2025-26 adopted millage with the standard $50,000 homestead exemption logic, the same math as our property tax estimator.
The loan
Default tracks the Freddie Mac 30-year weekly average. Adjust to your quoted rate.
Ownership costs
Northeast Florida homeowners commonly pay 0.5% to 1% of home value per year. Use a real quote when you have one.
Include monthly HOA dues plus one-twelfth of any annual CDD assessment. Estimate it with the CDD carrying cost calculator.

Common questions
How is a monthly mortgage payment calculated?
The principal and interest portion uses the standard amortization formula: the loan amount times the monthly rate, divided by one minus (1 plus the monthly rate) to the negative number of payments. On top of that, most Florida buyers pay property tax, homeowners insurance, possibly PMI, and any HOA or CDD assessment each month. This calculator totals all of it so you see the real number, not just the loan payment.
What is PITI?
PITI stands for principal, interest, taxes, and insurance, the four core parts of a monthly housing payment. Principal pays down the loan, interest pays the lender, taxes go to the county, and insurance protects the home. In Florida master-planned communities, HOA dues and CDD assessments come on top of PITI, which is why this calculator includes a field for them.
When does PMI drop off a mortgage?
Private mortgage insurance applies when you put down less than 20%. By federal law it must be canceled automatically once the loan balance reaches 78% of the original home value, and you can request cancellation at 80%. This calculator estimates the month your balance crosses 80% of the purchase price and shows how many years of PMI to budget.
How much is property tax on a Florida home?
It depends on the county millage rate and your exemptions. This calculator applies the county's FY2025-26 adopted millage with the standard $50,000 homestead exemption logic, the same math as our detailed property tax estimator. A new buyer's bill is usually higher than the seller's because the assessed value resets to near the purchase price when you buy.
How much cash do I need to close?
Plan for the down payment plus closing costs, which typically run 2% to 4% of the purchase price in Northeast Florida for things like lender fees, title, taxes, and prepaid escrow. This calculator defaults to 3% and lets you adjust it. Sellers sometimes contribute toward closing costs, which a Momentum agent can negotiate for you.
Does this calculator include HOA and CDD fees?
Yes. Enter the monthly HOA dues and one-twelfth of any annual CDD assessment in the HOA/CDD field. Many Florida buyers miss the CDD line on the tax bill, and in a master-planned community it can add $75 to $250 a month. Use our CDD carrying cost calculator to estimate it for a specific community.
