What is the 30% rent rule?

The common guideline says housing should consume no more than 30% of your gross income. Spending above that is considered cost-burdened and leaves less room for other needs and savings.

What is the median rent in Washington DC?

Median one-bedroom rent in Washington DC is around $2,600, with central and newer units costing more. Adjust the rent field to match the specific unit or neighborhood you are evaluating.

Should I use gross or net income?

The standard 30% rule uses gross (pre-tax) income because landlords typically screen on gross. The tool follows that convention, so enter income before taxes.

What if my ratio is just over 30%?

A ratio slightly above 30% is often workable if you have low debt and stable expenses, but it is a caution flag. The tool labels it cost-burdened so you can weigh the trade-off.

How is max rent calculated?

The tool multiplies your gross monthly income by 0.30 to give the maximum rent that keeps you within the guideline. Anything below that is considered affordable.

Can you afford that Washington DC rent?

The classic rule is simple: housing should stay at or below 30% of your gross income. With Washington DC’s median one-bedroom rent near $2,600, this calculator tells you instantly whether a unit fits your budget and what the most you should spend is.

How it works

The tool normalizes income to a monthly figure, computes your rent-to-income ratio, and compares it to the 30% threshold:

monthly income  = annual / 12   (or your monthly figure directly)
ratio           = rent / monthly income
max rent        = monthly income * 0.30
verdict         = ratio <= 0.30 ? affordable : cost-burdened

A ratio at or under 30% is affordable; between 30% and 50% is cost-burdened; above 50% is severely cost-burdened. Gross income is used because that is the standard landlords screen against.

Tips and example

On 9000 gross monthly income, your max recommended rent is 9000 * 0.30 = 2700. A 2600 Washington DC one-bedroom gives a ratio of 2600 / 9000 = 0.289, or about 29% — just within affordable range.

If your ratio runs high, look at outer neighborhoods or nearby Maryland and Virginia suburbs, or a roommate to split costs; the median rent assumes a solo one-bedroom.
