Idaho mortgage calculator
Prefilled with Idaho’s numbers, not national averages. The effective property tax rate here is 0.63% and the average homeowners premium is about $1,400 a year. Both are already in the calculator below.

Tax and insurance are collected alongside the loan but are not part of it, so they are excluded here.
What Idaho actually costs a homeowner
The homeowner's exemption removes up to a set share of assessed value, which meaningfully reduces the bill on modest homes.
On the state median home value of $417,800, the property tax bill works out at roughly $2,632 a year, or $219 a month before anything else. That is below the national effective rate of 0.86% — 0.7 times the US average.
Insurance is the other half of the escrow payment. At about $1,400 a year, Idaho sits below the national average of roughly $2,400. Together, tax and insurance add around $336 a month to the loan payment on a median-priced home here.
Why your bill will differ
The figure above is a state average, and property tax is set locally. Two houses of the same value in different counties of Idaho can carry bills that differ by thousands. Check your county assessor before treating any estimate as final, and check whether a homestead exemption applies to you — in most states it does, and in several it is substantial.
Close to the national middle
Idaho’s 0.63% sits near the national effective rate of 0.86%, which makes the local variation more important than the state average. County millage does more to your bill here than the state figure suggests.
Insurance is cheap here, and that matters
About $1,400 a year against a national average near $2,400. On a median-priced home that is roughly $83 a month less than a buyer in a coastal state pays for identical coverage — worth about $12,821 of additional borrowing power at current rates.
Tax and insurance are close to balanced
About $2,632 in tax against $1,400 in insurance, so neither dominates the escrow payment. Together they add roughly $336 a month before any principal or interest — the part of a housing budget that does not fall as you pay the loan down.
Stepping up from the median
At $630,000 — about half again the Idaho median — the annual tax becomes $3,969 and the escrow portion of the payment rises to roughly $447 a month. With 20% down at 6.5% over thirty years, the all-in payment is about $3,633.
