Montana Mortgage Calculator

The Home Price field is pre-filled with Montana's median home value (about $450,000). Override with your target home's actual price for a property-specific estimate.

The Property Tax Rate is pre-filled with Montana's average effective rate of 0.83%. Within Montana, rates vary by county — if you know your specific local rate from your county assessor or last tax bill, override it for a more precise estimate.

The Home Insurance default reflects Montana's typical annual premium of approximately $1,600.

Adjust the Down Payment slider to compare scenarios. Below 20% down triggers PMI; the calculator adds it automatically and flags it.
