About the Rent Calculator

This rent calculator helps you understand the true cost of renting by factoring in monthly rent, security deposit, move-in fees, and monthly utilities over the full lease term. It also supports roommate splitting — equally or by income ratio — and compares your rent to the 30% budget rule.

How to Use

  1. Enter the monthly rent, lease term in months, move-in costs, and monthly utilities.
  2. Optionally add roommates using the split toggle. Choose equal split or income-based split.
  3. Click "Calculate Costs" to see total cost, effective monthly cost, each person's share, and a budget recommendation.

FAQs

What is the 30% rent rule?

The 30% rule states that you should spend no more than 30% of your gross monthly income on housing costs. If your rent exceeds this threshold, you may be considered rent-burdened and have less flexibility for savings and other expenses.

How should roommates split rent?

Equal splitting divides the total rent evenly among all roommates. Income-ratio splitting assigns each person a share proportional to their income, so higher earners pay more. Both methods are common — the best choice depends on what your household agrees on.
