Idaho (ID) · State tax: 5.695% · Property tax: 0.69% · Median home (ZHVI): $465,000

In Idaho, the median home price is $465,000 as of 2026, which directly determines your loan amount and monthly payment. Property taxes run 0.69% annually — about $3,209/year on a median-priced home — and are typically rolled into your monthly PITI payment. Homeowners insurance averages $870/year in Idaho, adding roughly $73/month to your total housing cost. With a 5.695% state income tax, Idaho residents can potentially itemize mortgage interest deductions, reducing the effective cost of homeownership.
Home value, monthly carrying cost, property tax, and insurance are the four levers for the mortgage payment calculator in Idaho. Every row cites a primary public dataset. Numbers reflect the most recent vintage available; refresh cadence is documented in the methodology.
Every real-estate number on this page runs through the same core identity: the monthly principal-and-interest payment on a fully amortizing fixed-rate loan is M = P · r / (1 − (1+r)^(−n)), where P is the loan principal, r is the monthly rate (annual rate / 12), and n is the term in months. For a typical Idaho buyer in 2026, P starts from an $465,000 median home value (Zillow ZHVI)[1], minus a standard 20% down payment.
On top of P&I the calculator adds the two Idaho-specific carrying costs: property tax at the state effective rate of 0.69%[2] and homeowners insurance at roughly $870/year (NAIC state average)[3]. The Freddie Mac PMMS national average 30-year fixed rate (6.30% (Freddie Mac PMMS · week of ))[4] drives the payment curve — Idaho rate quotes can move a few basis points around that number depending on lender, loan size, and credit band.
Calc-specific note: For a fully amortising 30-year fixed, plug Idaho's ZHVI minus 20% down into the M = P·r/(1−(1+r)^−n) identity — output is principal + interest only.
Worked example — Idaho
A Idaho buyer purchasing the median home at $465,000 with 20% down ($93,000) borrows $372,000. At the PMMS 6.30% 30-year fixed, monthly P&I is $2,303. Add $267/month property tax (0.69% effective rate) and the typical Idaho homeowners premium to reach full PITI.

CalcFi pSEO pages combine three inputs: (1) the calculator formula itself, which runs client-side so no inputs leave your browser; (2) state-level financial constants from primary public datasets; and (3) national benchmarks for comparison. The Idaho page uses the property tax rate (0.69%), median home price ($465,000), and 5.695% state income tax from the sources listed below.
Refresh cadence:state tax brackets and minimum wage rates are reviewed annually after each state's legislative session. Property tax, median home price, insurance, and cost-of-living figures are reviewed annually against the primary sources. Income percentiles are refreshed when the Census CPS/IPUMS releases update (typically September). Page-level dateModified matches the last editorial review date, shown above.
Known limits: statewide averages mask large intra-state variance — county-level property tax and metro-level home prices differ significantly from the figures shown. For the most precise calculations, cross-check the output against your actual county assessor and the latest federal/state tax tables at filing time.
