No sign-up needed, shareable results included.
Rent Split
Your roommate with the master suite shouldn't pay the same as the person in the closet-sized room. Split rent by square footage, features, and income — with a Fairness Score.
Affordability
The 30% rule says you can afford $1,500/mo on a $60K salary. Factor in student loans and your real number drops to $1,100. Get your actual budget.
Prorated Rent
Moving in on the 15th of a 30-day month at $1,800/mo rent? You owe $960, not the full month. Calculate your exact prorated amount for any move date.
Rent Increase
Got a rent increase notice? See if it's above average, check if it's legal in your state, and get data-backed negotiation points to push back with.
Rent to Income
For a $2,000/mo apartment, landlords want $6,000/mo gross income (3x rule) or $80,000/yr (40x rule). Check if you qualify solo or with a co-applicant.
Rent vs Buy
At 7% mortgage rates, buying isn't automatically smarter than renting. Compare true costs over 1-30 years including equity, taxes, maintenance, and opportunity cost.
Couple Split
Should a couple sharing one bedroom pay double? Per-person says yes ($1,600). Per-room says no ($800). The fair answer is somewhere in between.
50/30/20 Budget
On a $4,500/mo take-home, the 50/30/20 rule gives you $2,250 for needs, $1,350 for wants, and $900 for savings. See your exact breakdown — adjusted for rent.
