The 30% rule is a widely-used guideline that says your gross monthly income should be at most 30% for housing costs (rent plus utilities). It's the standard used by most landlords and mortgage lenders. If you earn $4,500/month, your rent should stay under $1,350.

Senator Elizabeth Warren popularized the 50/30/20 budget framework:

• 50% — Needs: Rent, utilities, groceries, insurance, minimum debt payments.
• 30% — Wants: Dining out, subscriptions, entertainment, hobbies.
• 20% — Savings: Emergency fund, retirement, debt payoff beyond minimums.

Our calculator uses the 30% or 50% options to reflect the "Needs" portion being spent on rent.

• Negotiate your lease — Ask for 2–5% off if you've been a good tenant. Worst they say is no.
• Sign a longer lease — 18–24 month leases often come with lower monthly rates.
• Move to a cheaper area — A 15-minute commute difference can mean $300+/month.
• Find a roommate — Splitting a 2-bedroom often cuts your rent in half.
• Look for move-in specials — Many buildings offer first month free or reduced security deposit.
