Mortgage Calculator with Taxes and Insurance

This mortgage calculator with taxes and insurance is the PITI page in the mortgage set. It is for buyers and homeowners who already know that the principal-and-interest payment is not enough. Property taxes, homeowners insurance, PMI, and HOA dues can move a payment by hundreds of dollars, so this calculator makes those components visible instead of hiding them behind one total.

For a broader main payment estimate with optional extra payments, use the mortgage calculator. For a loan-only answer, use the simple mortgage calculator. For a payoff schedule, use the mortgage amortization calculator. For rate, points, fees, and APR-style comparisons, use the mortgage rate calculator.

What this PITI calculator does

The calculator starts with home price and down payment percentage. It subtracts the down payment from the purchase price to get the loan amount. It then calculates the fixed-rate principal-and-interest payment using the annual interest rate and loan term. Property tax is estimated from the home price and annual property-tax rate. Insurance is entered as an annual dollar amount and divided by 12. PMI is added when the down payment is under 20 percent. HOA dues are entered as a monthly amount.

The result shows the estimated monthly housing payment plus a breakdown of principal and interest, tax, insurance, PMI when applicable, and HOA dues. It also groups the loan amount, down payment, monthly escrow items, and estimated annual taxes and insurance. Escrow items in this calculator are tax, insurance, and PMI. HOA dues are shown separately because they are usually paid to the association, not into a lender escrow account.

Calculation

The loan amount is:

$\text{loan amount} = \text{home price} \cdot (1 - \text{down payment rate})$

For principal P, monthly interest rate r, and n monthly payments, the standard amortized-payment formula is:

$\text{M} = P \frac{r(1+r)^n}{(1+r)^n-1}$

The monthly PITI-style estimate is:

$\text{payment} = \text{M} + \text{monthly tax} + \text{monthly insurance} + \text{monthly PMI} + \text{monthly HOA}$

PMI is included only below 20 percent down:

Checking a mortgage calculator with taxes and insurance scenario

The default home price is 400,000 dollars with 15 percent down. That down payment is 60,000 dollars, so the loan amount is 340,000 dollars. The loan term is 30 years, or 360 monthly payments, and the interest rate is 6.75 percent. The principal-and-interest payment from the formula is 2,205.23 dollars.

Property tax uses the home price times the 1.1 percent annual tax rate. That is 4,400 dollars per year, or 366.67 dollars per month. Home insurance is 1,800 dollars per year, or 150.00 dollars per month. Because the down payment is below 20 percent, PMI is calculated from the 340,000 dollar loan amount times the 0.5 percent annual PMI rate, divided by 12, which equals 141.67 dollars per month. HOA dues are 75.00 dollars per month.

Add the pieces: 2,205.23 dollars of principal and interest, 366.67 dollars of tax, 150.00 dollars of insurance, 141.67 dollars of PMI, and 75.00 dollars of HOA dues. The estimated monthly housing payment is 2,938.57 dollars. Monthly escrow items are 658.33 dollars because the calculator adds tax, insurance, and PMI for that figure. Estimated annual taxes and insurance are 6,200.00 dollars, which is property tax plus annual insurance and does not include PMI or HOA dues.

Escrow and amortization work together but are different

Amortization reduces the loan balance. Each fixed principal-and-interest payment has an interest part and a principal part. Early payments are interest-heavy; later payments repay more principal. Escrow is different. It is a collection mechanism for bills such as property tax and homeowners insurance. Paying 366.67 dollars of monthly tax does not reduce the mortgage balance, even if it is collected by the lender alongside the mortgage payment.

PMI is also not principal. It may be required when the borrower has less equity, and it protects the lender rather than the homeowner. HOA dues are similar in the sense that they are part of monthly housing cash flow but not part of the loan payoff. This distinction matters when comparing homes: a lower loan payment can still be less affordable if taxes, insurance, PMI, and dues are higher.

Rate context and planning tips

The interest rate controls the loan portion, but the home price often controls several other inputs too. A higher-priced home usually means a larger loan, larger property-tax estimate, and possibly higher insurance. If two properties have the same price but one is in a higher-tax jurisdiction or an HOA community, the monthly total can differ materially.

Before relying on the estimate, check local property-tax rules, whether a purchase reassessment is likely, the insurance premium for the specific property, and the HOA budget. Compare down-payment scenarios with the down payment calculator, test affordability with the home affordability calculator, and isolate rate effects with the mortgage rate calculator.
