What this calculator does
When a landlord raises the rent, the question is what it really means for your budget. Enter your current rent and either the new rent or the percentage. The calculator shows the increase per month and in percent, what it costs over 12 months, how much of your income goes to rent before and after, and how the new rent compares with your current rent raised by an inflation rate you choose.
How it is worked out
Increase = new rent − current rent; percent = increase ÷ current rent × 100. Extra per year = increase × 12. Share of income = rent ÷ monthly household income before tax. Example: rent going from $1,800 to $1,950 is a $150 (8.3%) increase, or $1,800 more over a year. With $6,000 of monthly income, rent goes from 30% to 32.5% of income. Raised by 3% inflation, the old rent would be $1,854, so the new rent is $96 above inflation.
The 30% guideline
The U.S. Department of Housing and Urban Development (HUD) considers households that pay more than 30% of their income for housing to be cost burdened, and those paying more than 50% severely cost burdened (HUD). It is a rule of thumb, not a law, and housing costs can also include utilities.
Your rights as a renter
Notice periods and any limits on increases are set by state and local law, so they differ a lot from place to place. A few states and some cities limit yearly increases for many rentals. HUD keeps a list of tenant rights, laws and protections by state (HUD tenant rights). If you live in subsidized housing, rent rules depend on the program.
Frequently asked questions
How do I calculate a rent increase percentage?
Subtract the old rent from the new rent, divide by the old rent and multiply by 100. From $1,800 to $1,950: $150 ÷ $1,800 × 100 = 8.3%.
How much can a landlord raise the rent?
In most places there is no set limit, but a few states and some cities cap yearly increases for many units, and notice rules apply almost everywhere. Check your state's rules.
How much rent can I afford?
A common guideline is 30% of income before tax. The rent affordability calculator also looks at your other debts.
Is the "keeps rising" number a forecast?
No. It only shows what happens if the same percentage increase repeated every year.
