What $74,988 take-home means in Idaho

  • Hourly: $100,000 is $48.08 an hour before tax and about $36.05 an hour after tax, at 40 hours a week.
  • Local prices: Idaho's price level is 95.5% of the U.S. average (BEA Regional Price Parities), so $74,988 buys about what $78,527 would at national-average prices.
  • A 50/30/20 budget: about $3,125 a month for needs, $1,875 for wants and $1,250 for savings. Plan it in the budget calculator.
  • Rent: the 30% rule points to about $2,500 a month. Check it with your debts.
  • Saving 6% in a 401(k): puts $6,000 a year into retirement but lowers take-home by only $4,362, because traditional contributions skip federal income tax and Idaho income tax.
  • Married, one income: filing jointly, take-home would be about $81,627.
