How to use this calculator
The Home Price field is pre-filled with the median home value in Washington (about $620,000). Override with your target home's actual price to get a payment estimate for that specific property.
The Property Tax Rate is pre-filled with District of Columbia's average effective rate of 0.57%. Within District of Columbia, rates vary by county — if you know your specific local rate, override it for a more precise estimate.
Adjust the Down Payment slider to see how your payment changes. Below 20% down triggers PMI; the calculator adds it automatically and shows a warning.

How it works
Buying a median-priced home in Washington. At $620,000 with a 20% down payment, you'd bring $124,000 to closing (plus closing costs) and take out a $496,000 mortgage. At a 6.50% interest rate on a 30-year fixed loan, your monthly principal + interest is roughly $3,135.
Annual costs on top of the loan. District of Columbia's average property tax rate is 0.57%, so a median-priced Washington home generates approximately $3,534 in annual property tax (about $294/mo when paid through escrow). Homeowner's insurance in District of Columbia averages around $1,100/year.
Total monthly payment (PITI) on the median Washington home works out to about $3,521 per month at current rates, assuming a 20% down payment and no HOA. If you're putting less than 20% down, add PMI to this — typically 0.5–1.5% of the loan balance per year.
Rates change; this is the math, not the offer. Mortgage rates fluctuate daily. Our default of 6.50% is a recent conventional 30-year benchmark — enter today's quoted rate from your lender for the most accurate payment estimate.
