How to Estimate Property Tax and Insurance for Your Mortgage

Your full mortgage payment includes more than principal and interest. Property taxes and home insurance can add hundreds of dollars per month. This guide explains how to estimate both so you can use the Mortgage Payment Calculator with realistic numbers.

Estimating Property Tax

Property tax is set by local governments and is usually a percentage of the home’s assessed value. You can look up the mill rate or effective rate for the area, then multiply by the purchase price (or assessed value). Typical effective rates range from about 0.5% to 2% of value per year. A $400,000 home at 1.2% might mean $4,800 per year, or $400 per month. Check the listing or the county assessor’s site for the current year’s tax on the property.

Estimating Home Insurance

Homeowners insurance depends on replacement cost, location, and coverage. Get quotes from a few insurers; for a $300,000–$400,000 home, annual premiums often fall in the $1,200–$2,000 range. Divide by 12 for a monthly estimate. Lenders require enough coverage to protect their interest in the property.

Including Them in Your Budget

Add monthly tax and insurance to the principal-and-interest result from the calculator to get your full payment. Lenders use this full payment when computing your debt-to-income ratio. For more on affordability, see how much house you can afford.

Practical Takeaway

Estimate property tax from local rates and the home’s value; estimate insurance from quotes. Enter tax and insurance in the Mortgage Payment Calculator to see your true monthly housing cost.
