2. Smart Budget (50/30/20 Rule)

Using your monthly net pay of $6,134, here is how the 50/30/20 rule applies in Rexburg.

• Needs (50% - $3,067)

  • Rent (1BR/Studio): $1,050 - $1,250 (Market average; excludes the "None" placeholder).
  • Utilities: $200 - $300 (Heating is expensive in winter; electricity/water moderate).
  • Groceries: $400 - $500 (Grocery prices in Rexburg are often higher than the national average due to logistics).

• Wants (30% - $1,840)

  • Discretionary spending. Dining out, entertainment, hobbies.
  • Warning: If your "Needs" bleed into this category (e.g., high car payment), this slice vanishes.

  • Student loans, credit cards, 401k, emergency fund.
  • This is the only number that matters for long-term financial health.

3. Rexburg Tax Context

Idaho is a Low-Moderate Tax State compared to the national average, but it is not a tax haven.

• Vs. Texas/Florida: You are paying ~$4,900 more in state income tax annually than you would in a zero-income-tax state. However, Idaho property taxes are generally lower than Texas.
• Vs. California/NY: You are saving roughly $6,000 - $8,000 annually in state income tax compared to high-tax coastal states.
• Sales Tax: Rexburg City + Madison County sales tax is 6%. This is the "hidden tax" that impacts your purchasing power on everything except groceries (which are taxable at 0% in Idaho).

4. FAQ

"Is $100k good here?"
Yes, but it is not "wealthy." A $100k salary puts you comfortably in the middle-to-upper income bracket for Rexburg. You will live alone, drive a reliable car, and save money if you stick to a budget. However, housing prices have risen sharply; $100k does not stretch as far as it did five years ago.

"Local income tax?"
No. Rexburg does not levy a local income tax. Your income tax liability is strictly Federal and State (Idaho).

"What about the 'None' rent?"
If you find a verified unit for significantly below the $1,050 average, take it. If you are forced into the $1,400+ range (new builds/renovated units), the 50/30/20 budget collapses unless you reduce savings or find a roommate.
