Calculate a realistic rent budget, compare rent versus buy costs, and split rent or utilities between roommates with a free online rent calculator.
Rent budget
A rent budget should compare a simple income rule with your real monthly cash flow. The calculator uses income, take-home pay, utilities, groceries, transport, debt payments, savings targets, and other expenses to estimate a more practical rent limit.
Rent vs buy
Renting decisions are not only about monthly rent. Use the comparison tab to review rent increases, home price, down payment, property tax, insurance, mortgage rate, investment return, and time horizon. Use the roommate tab to divide rent and bills more fairly.
Use cases
Use it before signing a lease, comparing apartments, splitting rent with roommates, or deciding whether renting or buying makes more sense.

Questions
A rent calculator estimates how much monthly rent may fit your income, take-home pay, expenses, debts, utilities, and savings goals. It can also compare renting versus buying and split rent between roommates.
A common guideline is to keep rent around 30% of gross monthly income, but the right number depends on take-home pay, debt payments, utilities, savings goals, location, and personal expenses.
Yes. The roommate split tab can divide rent and utilities equally, by income, or by room size, depending on how you want to share costs.
No. Rent versus buy results are estimates only and depend on assumptions such as rent increases, home appreciation, mortgage rate, investment return, taxes, insurance, and how long you stay.
