What the Mortgage Insurance Cost Calculator is for
Calculate visitor-entered upfront and recurring mortgage-insurance costs without assuming a program.
It keeps the property value, balance, cash amounts, rate convention, payment timing, and comparison horizon visible so the result can be checked against an actual quote, statement, budget, or contract.
Calculation structure
Follow the money through time

Quick guide
How to use this calculator
Enter the figures from your mortgage offer, statement, contract, property budget, or scenario.
Keep currencies, rate conventions, periods, and balances consistent; compare multiple plausible scenarios where future rates or costs are uncertain.
Use the component outputs to verify the result and review the calculator-specific boundary before acting.
Calculation method
Calculation method
Upfront premium = principal × upfront rate; recurring premium = principal × annual rate ÷ 12 × entered months.
Mortgage schedules use stable level-payment arithmetic and advance only the explicitly entered scenario. Results are checked for finite, principal-reducing behavior and round only for display.
