The true monthly cost
of owning any U.S. home

The Forgely Cost to Own Any Home calculator estimates the true monthly cost of owning a specific U.S. property by combining six components: mortgage payment (principal and interest), property tax, homeowner's insurance, utilities, PMI if your down payment is under 20%, and HOA fees if applicable. You enter an address and optional purchase parameters, and the tool fetches real local data to build your estimate.

Yes. If you expand the "Adjust assumptions" panel, you can enter a specific purchase price, down payment percentage, loan term (15 or 30 years), and interest rate. By default, the calculator uses the county median home value from Census data. If you are evaluating a specific property you know the asking price for, entering that price gives you a more precise estimate.

Yes. The "Adjust assumptions" section lets you enter a monthly HOA fee. This amount is added to your total monthly cost and displayed as a separate line item in the breakdown. HOA fees for condos can range from $100 to over $1,000 per month depending on the community's amenities and reserves, so including this is essential for accurate planning.

Use the estimate to set a realistic budget before approaching lenders. A common rule of thumb is that total housing costs should not exceed 28% of gross monthly income (the "front-end ratio"). Once you have your estimate, compare it against the 28% threshold to gauge affordability. Then contact a mortgage lender for a pre-approval that gives you an actual rate offer — the Forgely estimate uses a default 30-year rate that may differ from your actual quote.

The calculator pulls from three free government sources: the U.S. Census Bureau Geocoder (to locate the property and identify the county), the Census American Community Survey 5-year estimates (for median property tax and home values in that county), and the FEMA National Flood Hazard Layer (to check whether the address falls in a high-risk flood zone). Utility and insurance costs are derived from curated state-level averages.

Property taxes are estimated using Census ACS data for the county where the address is located. The calculator divides the county's median annual property tax by the county's median home value to derive an effective tax rate, then applies that rate to your purchase price. This gives a realistic, locally-calibrated estimate rather than a national average. Actual tax bills vary by municipality and assessment date, so treat this as a planning estimate.

Utility costs — electricity, gas, water, and trash — are estimated using curated state-level monthly averages derived from U.S. Energy Information Administration and utility benchmarking data. Costs are reflected as a single monthly line item. Actual utility costs vary widely based on home size, age, climate, and usage habits. The state averages are calibrated for a median-sized single-family home.

PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a standard monthly mortgage payment. Principal is the portion of each payment that reduces your loan balance. Interest is the lender's cost of lending. Taxes refers to property taxes collected monthly and held in escrow. Insurance refers to homeowner's insurance, also collected monthly. Forgely's calculator shows PITI plus utilities, PMI, and HOA as separate line items so you see the full picture.

PMI stands for Private Mortgage Insurance. Lenders require it when your down payment is less than 20% of the home's purchase price. PMI typically costs 0.5–1.5% of the loan amount per year, added to your monthly payment. The Forgely calculator defaults to 0.9% annually. PMI automatically drops off when your loan balance reaches 80% of the original purchase price — the Pro tier shows you exactly which month that happens on your amortization schedule.

Homeowner's insurance costs vary significantly by state. The calculator uses state-level monthly insurance averages scaled to your purchase price relative to a $250,000 baseline. States with high storm or wildfire risk (Florida, Louisiana, Oklahoma, Texas) carry substantially higher premiums than states with milder risk profiles. These are estimates — your actual premium depends on the home's age, construction type, and claims history.

FEMA designates certain areas as Special Flood Hazard Areas (SFHAs) — zones A, AE, AH, AO, AR, A99, V, and VE. If your address falls in one of these zones, mortgage lenders require you to purchase flood insurance, which is separate from standard homeowner's insurance. The National Flood Insurance Program (NFIP) average premium is approximately $74/month. The Forgely calculator checks your address against FEMA's National Flood Hazard Layer and adds flood insurance to your estimate automatically.

If the FEMA lookup returns no data for the address — which can happen in areas not yet mapped or in unmapped rural zones — the calculator defaults to assuming no flood risk. If you are purchasing in a coastal, low-lying, or riverine area, verify the flood zone independently using FEMA's Map Service Center at msc.fema.gov before making an offer.

It is the NFIP national average. Actual flood insurance premiums vary significantly based on FEMA's Risk Rating 2.0 methodology, which considers the specific property's flood frequency, proximity to water, and cost to rebuild. Properties in coastal V zones or high-frequency flood areas can cost several hundred dollars per month. The $74 figure is a planning baseline; request an actual flood insurance quote from an NFIP-authorized insurer for any property you are seriously considering.

The calculator produces planning-quality estimates, not quotes. Property tax rates vary by assessment district within a county, insurance premiums depend on the home's age and construction, and utility costs vary by household size. Expect actual costs to fall within 10–20% of the estimate in most cases. The goal is to give you a realistic monthly range before you talk to a lender or make an offer — not to replace a mortgage quote.

The most common reason for a high estimate is that the county median home value is much lower than the purchase price you are considering — the calculator's default rate reflects median market conditions. Enter your actual purchase price in "Adjust assumptions" to get a better calibrated result. Estimates may also run low in states where utilities or insurance are significantly above the state average for a specific micro-region.

Forgely Home Cost Pro ($9.99/month) adds: a full 30-year amortization table showing principal vs. interest month by month, a PMI removal timeline showing the exact month PMI drops off, the ability to compare up to three addresses side by side, and a printable PDF report. The free tier provides the full monthly cost estimate and breakdown for a single address with no ads shown.

Real estate agents can embed the Forgely Cost to Own Calculator on their own website with custom branding — their photo, name, brokerage logo, and brand color. When a buyer runs a search, they see the agent's branding and are prompted to enter their name, email, and phone to receive the full breakdown. The agent receives the lead instantly by email. Agent plans start at $39/month for the Solo tier (100 leads/month) and $149/month for Team (500 leads/month).

Yes. The full monthly cost estimate, PITI breakdown, flood zone check, PMI calculation, and stacked cost chart are all free with no account required. The Pro tier adds amortization detail, PMI removal timeline, address comparison, and PDF export for $9.99/month.

The address you enter is sent to Forgely's Cloudflare Worker, which uses it to query government APIs and return local cost data. Your address and results are not stored or associated with your identity in any way. The Worker uses short-term caching keyed by location — not by user — so repeat lookups for the same area return faster without re-querying the government APIs. No financial information you enter is transmitted anywhere.

When you use the calculator embedded on an agent's website and submit your lead information (name, email, phone), that data is sent to Forgely's Worker, stored securely, and forwarded to the agent by email. The address you searched and the cost estimate are included with the lead so the agent has context. This data is not shared with third parties or used for advertising.
