Mortgage Calculator

Monthly payment calculator with county-specific FHA limits, real PMI rates, and FHA-vs-Conventional comparison.

A mortgage calculator estimates your monthly principal, interest, taxes, insurance, and PMI payment based on home price, down payment, interest rate, and loan term. ValiFit's calculator pulls real county-specific FHA loan limits from HUD, current FHA Mortgage Insurance Premium (MIP) rates, and Conventional PMI tiers — surfacing the cheapest viable loan type for any property.
