As answered by people managing MorgCalc and https://open-gpt.app/.
MorgCalc's answer
Most mortgage calculators either lowball the real payment by only showing principal and interest, or gate the full breakdown behind an email signup. MorgCalc shows the complete monthly payment — principal, interest, property tax, and homeowners insurance — using state-specific tax rates instead of a national average, and automatically factors in PMI when the down payment is under 20%. It also checks the payment against the 28% housing-to-income benchmark lenders actually use, so you know where you stand before talking to anyone. No signup required.
MorgCalc's answer
The calculator itself is fully free with no email gate — you get the complete number immediately, not a teaser followed by a signup wall. It's also more accurate than calculators that only show principal and interest: MorgCalc includes property tax, insurance, and PMI by default, using real state-level tax data rather than a flat national estimate.
MorgCalc's answer
Home buyers and prospective home buyers — especially first-time buyers — doing affordability research before contacting a lender or real estate agent. People checking whether they can afford a specific listing, comparing scenarios across different down payments or interest rates, or estimating what property tax and insurance will actually cost in their state.
MorgCalc's answer
I built MorgCalc after running into the same problem with every existing mortgage calculator: they either underestimated the real payment by skipping taxes and insurance, or hid the full breakdown behind an email form. I wanted something that just showed the real number — instantly, accurately, and without a signup wall.
