Gross Income Multiplier Calculator

GIM = purchase price ÷ gross annual income. Unlike cap rate, it ignores operating expenses — fine for quick screening of similar properties in the same market. Useful for broker comp analysis on small multifamily.

Workforce / class C typical

How the math works

$850K ÷ $96K = 8.85 GIM — class B/workforce tier. Quick screen: acceptable for a cash-flow focused rental in a decent neighborhood. Not a complete analysis.

Follow up with cap rate using actual NOI, not gross income. GIM can make two properties look the same when one has $4K/mo opex and the other has $7K — massive NOI gap hidden.

How this calculator works

What this page estimates

This Gross Income Multiplier Calculator is built to give a quick, browser-based estimate for gross income multiplier. GIM = purchase price ÷ gross annual income. Unlike cap rate, it ignores operating expenses — fine for quick screening of similar properties in the same market. Useful for broker comp analysis on small multifamily. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.

How to interpret the gross income multiplier result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this gross income multiplier estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions

GIM vs cap rate?

GIM is gross (ignores opex). Cap rate uses NOI (after opex). GIM is faster but less honest. Use GIM for quick same-market screening; use cap rate for investment decisions.

What's a good GIM?

Class A urban multifamily: 12-18. Class B suburban: 8-12. Class C / small multifamily: 6-9. Single-family rentals: 8-14. Below 6 usually signals a high-risk property or local distress; above 18 means you're relying on appreciation, not cash flow.

Is GIM outdated?

Older metric but still used in commercial brokerage. Don't rely on it as the only screen — two buildings with identical GIM can have wildly different NOI if one has utility-inclusive rents and the other doesn't.

Scheduled vs actual income?

GIM uses scheduled (gross potential) income in most formulas. For real underwriting, use effective gross income (after vacancy and concessions). Make sure you're comparing like-for-like when using GIM for comps.
