A mortgage calculator that knows what state the house is in: principal and interest, plus Idaho property tax at the state's effective rate (0.42% of value, ACS 2025 medians) and a closing-cost estimate in the CFPB's typical 2–5% range.
Loan: $366,240. Insurance estimated at 0.2% of value per year inside the monthly total.
P&I $2,315 · tax $160 · insurance $76
| Principal & interest / month | $2,315 |
| Property tax / year (0.42% effective) | $1,923 |
| Closing costs (one-time, estimate) | $10,987 |
| Total interest over the term | $467,119 |
The Census Bureau's ACS 2025 medians put Idaho's typical bill at $1,924 on a $457,800 home — an effective 0.42%. Effective rates blend every local levy into one comparable number; your parcel's assessed value and local rates set the real bill.

The CFPB puts typical buyer closing costs at 2–5% of the loan (origination, appraisal, title, prepaid escrows). The default here is 3% and the field is yours to change — no official schedule exists, and this page will not pretend one does. Idaho transfer/recording charges sit inside that range for most purchases.

Property tax. At 0.42%, Idaho adds $160 a month on the median home — in the highest-tax states that rivals a full percentage point of interest rate.
No — it is the state's median effective rate applied to your price. Assessments, exemptions (homestead and others) and local rates move real bills both ways; the county assessor's figure governs.
Below 20% down, lenders usually add private mortgage insurance (roughly 0.3–1.5% of the loan per year) until you reach ~20% equity. It is not in the default total — add it to the insurance line mentally if it applies.
