About MyClosingCalc
Delivering mathematical transparency to real estate transactions, transfer taxes, and closing cost breakdowns across New York, California, New Jersey, and major US metropolitan markets.
Our Mission
Closing costs represent one of the largest cash outlays in any residential or commercial real estate transaction, often totaling tens of thousands of dollars in municipal transfer fees, progressive mansion taxes, mortgage recording duties, and title premiums. For decades, buyers, sellers, and agents relied on murky ballpark estimates and fragmented municipal fee schedules.
MyClosingCalc was established to provide absolute transactional clarity. We transform complex legislative tax brackets, municipal ordinances, and promulgated title rate filings into free, instant, and deterministic calculation engines.
Real Estate Tax Editorial & Review Board
Our analysis and calculators are governed by an institutional research desk specialized in municipal conveyance taxation, title insurance regulations, and settlement economics.
Every article, regional tax guide, and calculation formula is reviewed against three non-negotiable standards:
- Statutory Exactness: Incorporating precise tiered brackets (such as NYC's progressive 1.00% to 3.90% Mansion Tax thresholds under NYS Tax Law § 1402-a, and LA Measure ULA brackets).
- Jurisdictional Nuance: Explicitly isolating county-level variations, recording exemptions, condo vs. co-op transfer duties, and buyer vs. seller statutory liability.
- Zero Speculative Estimates: Our calculations are never based on approximate rules of thumb; they mirror the exact mathematical tables used by settlement attorneys and title closing agents.
Our 4-Step Verification Methodology
We pull rate matrices directly from published state tax statutes (NYS Department of Taxation & Finance, California CDTFA, NJ Division of Taxation) and county recording schedules.
Title insurance premiums are derived from officially promulgated rate manuals filed with state insurance departments, including the Title Insurance Rate Service Association (TIRSA).
Mathematical engines are stress-tested across edge-case transaction values (e.g. exactly at statutory cliff thresholds like $1,000,000, $2,000,000, and $5,000,000) to ensure zero rounding errors.
When municipal ballot measures or budget bills revise transfer brackets (e.g., Chicago Bring Chicago Home, LA Measure ULA threshold revisions, or NY state budget adjustments), all logic files are updated proactively.
