# TrueMonthly > The brutally honest mortgage calculator that shows the true monthly cost of homeownership — not just principal and interest. TrueMonthly is a free, privacy-first mortgage calculator that reveals the full cost of owning a home. Unlike basic calculators from Zillow, Bankrate, or NerdWallet that only show principal and interest, TrueMonthly includes maintenance reserves (1-2% of home value annually), utilities, PMI, property taxes, insurance, and HOA fees. Users can compare up to 3 mortgage scenarios side-by-side and check affordability against their real lifestyle budget. ## Key Features - True Cost Calculator: Shows the full monthly cost including maintenance, utilities, taxes, insurance, PMI, and HOA — typically 25-40% higher than basic P&I calculators show. - Scenario Comparison: Compare up to 3 mortgage scenarios side-by-side (e.g., 15-year vs 30-year, 5% down vs 20% down). - Lifestyle Affordability Check: Uses your actual take-home pay and real expenses instead of bank DTI ratios. - Cash to Close Breakdown: Shows total cash needed including down payment, closing costs, reserves, and move-in budget. - Extra Payment Impact: See how extra monthly payments reduce your loan term and total interest. - Refinance Calculator: Break-even analysis for refinancing with monthly savings and lifetime savings projections. - Privacy-First: All calculations run client-side in the browser. No data is collected, stored, or transmitted. ## Common Questions This Tool Answers - What is the true monthly cost of owning a home? - How much house can I afford based on my actual budget? - How much total cash do I need to buy a house? - Should I get a 15-year or 30-year mortgage? - How much does an extra $200/month save on my mortgage? - When does refinancing make financial sense? - What is the reality gap between what basic calculators show and actual costs? ## Quick Facts - Average reality gap: 25-40% higher than basic P&I payment - Maintenance reserves: Budget 1-2% of home value per year - Cash to close: Typically 15-20% of home price (not just the down payment) - PMI threshold: Required when down payment is below 20% - Refinance break-even: Typically 2-4 years depending on rate reduction and closing costs ## City-Specific Cost Guides TrueMonthly provides detailed true-cost analyses for 10 major US housing markets: - Austin, TX: Median $530K, 2.0% property tax, $350/mo utilities (summer electricity spikes) - Denver, CO: Median $599K, 0.55% property tax, $300/mo HOA fees common - Phoenix, AZ: Median $435K, 0.62% property tax, $380/mo utilities (extreme summer AC) - Nashville, TN: Median $475K, 0.95% property tax, 2025 reappraisal +45% - Charlotte, NC: Median $404K, 1.0% property tax, nearly universal HOA fees - Raleigh, NC: Median $434K, 0.85% property tax, Research Triangle tech boom - Tampa, FL: Median $430K, 0.89% property tax, $252/mo insurance crisis - Dallas, TX: Median $435K, 2.2% property tax, hail insurance costs - Atlanta, GA: Median $400K, 1.44% property tax, high commute costs - Jacksonville, FL: Median $303K, 0.97% property tax, most affordable FL city Each city guide includes: hidden costs breakdown, neighborhood comparisons, market insights, FAQ, and a pre-filled calculator. ## URL https://truemonthly.com
