Affordable rent = gross monthly income × rent-to-income limit ÷ 100= 1200
Note
This is a simplified model: it applies the standard property-management definition to the numbers you entered. Rent affordability uses a flat share-of-income rule and ignores credit history, local screening criteria and household size. Proration assumes a plain daily rate; your lease or local law may prescribe a different convention (for example a fixed 30-day month). Security-deposit interest is simple interest at the rate you enter, while many jurisdictions set the rate, the compounding and the payout schedule by statute. Income, expense, reserve and escalation figures are straight-line and assume the amounts you enter hold steady; they ignore taxes, depreciation, financing changes, capital events, inflation and market turnover. Lease buyout compares the contractual penalty with the remaining rent only and is not a reading of your lease. These results are general information, not legal, tax or investment advice: check your lease and local tenancy law and consult a qualified professional before acting.

What is the general rule this calculator is based on?+
It's usually based on the common '30% rule': rent should ideally not exceed about 30% of gross (pre-tax) monthly income, a widely used affordability benchmark, though it's a guideline rather than a hard financial law.
Why 30% specifically, and is it still realistic today?+
The 30% threshold originated from U.S. housing policy standards decades ago; in many high-cost markets today it's increasingly difficult to stay under it, so some renters and landlords now treat 35-40% as a more realistic (if less conservative) ceiling depending on the local market and the renter's other debts.
Should I use gross or net income for this calculation?+
Most affordability guidelines, including the 30% rule, are based on gross (pre-tax) income, so use that figure unless a specific local program or landlord standard specifies net income instead.
Why do landlords often ask for income to be 3x the rent?+
That's effectively the same 30% threshold restated from the other direction — if rent should be about a third of income, then income needs to be roughly three times the rent, which is how many landlords and screening services phrase their minimum income requirement.
Does this affordability estimate account for other debts I have?+
No — a basic rent affordability calculation only looks at income versus rent; it doesn't factor in student loans, car payments, or credit card debt, so someone with significant other debt obligations may need a lower rent-to-income ratio than the standard guideline to remain comfortable.
