Estimate monthly and annual rent as a chosen share of area median income. This calculator does not determine official affordable-housing rent limits or eligibility.

Estimate rent as a chosen share of area median income. Select whether your AMI amount is annual or monthly. This is not an official affordable-housing rent limit.

Use the published AMI for the relevant area and household size. Annual input is selected initially.

This is the rent share, not the household’s AMI eligibility percentage. No percentage is assumed.

AMI Rent Formula

Annual rent = Annual AMI × (P / 100); Monthly rent = Annual rent / 12
  • Annual rent = the annual estimate based on a chosen percentage of area median income
  • AMI = area median income in dollars; select annual or monthly input
  • P = percentage of AMI used as rent

The calculator multiplies the AMI amount by the percentage you enter, after converting that percentage to a decimal.

The primary result is monthly rent, with annual and weekly equivalents also shown. Monthly AMI is converted to annual AMI before calculation. Changing the input period converts the current amount.

  • Calculate uses the AMI rent formula and displays rounded dollar amounts.
  • Reset clears the AMI, percentage, rent result, and calculation steps.
  • Calculation details displays the input values and the multiplication used to get the result.

Common Rent Percentages of AMI

These are illustrative shares, not official AMI rent limits. A household affordability benchmark uses that household’s income, not area median income. The calculator accepts nonnegative percentages.

Percentage of AMI as Rent Meaning
25% Lower share of the entered AMI
30% 30% of AMI; not a household affordability determination
35% Higher share of the entered AMI
40% 40% of the entered AMI; household rent burden is not determined

Annual and Monthly Rent Conversion

The calculator shows monthly, annual and weekly equivalents using these conversions.

If the Calculator Result Is Use This Conversion
Annual rent Monthly rent = annual rent ÷ 12
Monthly rent Annual rent = monthly rent × 12
Weekly rent equivalent Weekly rent = annual rent ÷ 52

Example Problems

Example 1: Rent at 30% of AMI

Suppose the area median income is $80,000 and the rent percentage is 30%.

AMI Rent = 80000 × (30 / 100)
AMI Rent = 80000 × 0.30 = 24000

The AMI rent is $24,000. If the AMI was entered as an annual amount, that equals $2,000 per month.

Example 2: Rent at 25% of AMI

Suppose the area median income is $65,000 and the rent percentage is 25%.

AMI Rent = 65000 × (25 / 100)
AMI Rent = 65000 × 0.25 = 16250

The AMI rent is $16,250. If the AMI was entered as an annual amount, that equals about $1,354.17 per month.

FAQ

Is the AMI rent result monthly or annual?

The primary result is monthly rent regardless of the selected input period. Annual and weekly equivalents are also displayed.

What percentage should I use for rent?

Choose the share for your illustrative calculation. A 30% household-income benchmark is not the same as 30% of AMI. Official program rents may involve income limits, household or bedroom adjustments and utilities; consult the applicable housing agency.

Is AMI the same as household income?

No. AMI means area median income, which is the median income for a specific area. Household income is the income for one household. Affordable housing programs often compare household income to AMI, but they are not the same number.
