REAL ESTATE INVESTING METRICS CHEAT SHEET

A plain-English guide to what each metric means, how it’s calculated, and who actually uses it.

The easiest way to understand investing metrics is to ask one question first:

Is this measuring the property, my return, the loan, or the price?

No single metric tells you whether an investment is good or bad. Each one gives you a different piece of the picture.

1. PROPERTY PERFORMANCE

How is the property itself performing?

These metrics focus on the actual asset before your personal financing structure changes the picture.

Net Operating Income — NOI

What it means:The income left over after paying the normal operating expenses of the property, but before mortgage payments and income taxes.

Formula:NOI = Effective Gross Income − Operating Expenses

What it tells you:How much operating income the property itself produces.

Who uses it:Investors, lenders, appraisers and brokers.

Quick note:Mortgage payments are not considered an operating expense when calculating NOI.

Capitalization Rate — Cap Rate

What it means:The return the property produces before considering financing.

Formula:Cap Rate = NOI ÷ Property Value

or

Cap Rate = NOI ÷ Purchase Price

What it tells you:How much operating income the property generates relative to its value.

Who uses it:Investors, brokers, appraisers and lenders.

Quick note:Cap rate is most useful when comparing similar income-producing properties in similar markets.

Operating Expense Ratio — OER

What it means:The percentage of the property’s effective income that gets spent operating it.

Formula: OER = Operating Expenses ÷ Effective Gross Income

What it tells you:How much of the property's income is being consumed by expenses.

Who uses it:Investors, asset managers and lenders.

Example:If a property collects $100,000 and has $40,000 in operating expenses:

$40,000 ÷ $100,000 = 40% OER

2. INVESTOR RETURNS

How is my money performing?

These metrics focus on the return being generated on the investor's actual equity.

Cash-on-Cash Return — CoC

What it means:The annual cash flow you receive compared with the amount of cash you invested.

Formula:CoC = Annual Pre-Tax Cash Flow ÷ Total Cash Invested

What it tells you:How much current cash flow your invested money is producing.

Who uses it:Primarily investors.

Example:You invest $100,000 and receive $8,000 of annual cash flow:

$8,000 ÷ $100,000 = 8% CoC

Quick note:Cash-on-cash return focuses on current income. It does not measure your entire return over the life of the investment.

Internal Rate of Return — IRR

What it means:An estimate of your annualized return over the entire investment period.

Unlike cash-on-cash return, IRR considers when money is invested and when money is received.

Formula:IRR is the discount rate that causes the net present value of all investment cash flows to equal zero.

In simple terms:

IRR measures your annualized return while accounting for the timing of your money.

What it tells you:The estimated overall annual return generated by the investment throughout the entire holding period.

Who uses it:Investors, analysts, private equity firms and institutional investors.

IRR can include:

• Initial investment

• Annual cash flow

• Refinancing proceeds

• Additional capital invested

• Sale proceeds

Quick note:IRR is only as good as the assumptions used in the calculation.

Equity Multiple

What it means:How much total money comes back to you compared with how much equity you invested.

Formula:Equity Multiple = Total Cash Distributions ÷ Total Equity Invested

What it tells you:How many dollars you received for every $1 invested.

Who uses it:Investors and investment managers.

Example:You invest:

$100,000

Over the entire investment, you receive:

$200,000

Your equity multiple is:

$200,000 ÷ $100,000 = 2.0x

That means you received $2 for every $1 invested, including your original capital.

The easiest way to remember these three:

CoC = How much cash am I making now?

IRR = What is my annualized return over time?

Equity Multiple = How much money did I ultimately get back?

3. DEBT, FINANCING & RISK

Can the deal safely support the loan?

These metrics help determine how much debt the property is carrying and how comfortably the property can support that debt.

Debt Service Coverage Ratio — DSCR

What it means:A comparison between the property's NOI and the amount required to make its loan payments.

Formula:DSCR = NOI ÷ Annual Debt Service

What it tells you:How many times the property's NOI covers its annual mortgage payments.

Who uses it:Primarily lenders, but investors should pay attention to it too.

Example:

NOI:

$125,000

Annual debt service:

$100,000

DSCR:

$125,000 ÷ $100,000 = 1.25x

The property generates 1.25 times the income required to service its debt.

Quick note:Different lenders and loan programs may calculate DSCR slightly differently.

Debt Yield

What it means:The property's NOI compared with the amount of money the lender has loaned against the property.

Formula:Debt Yield = NOI ÷ Loan Amount

What it tells you:How much income the property produces relative to the lender's exposure.

Who uses it:Primarily commercial and multifamily lenders.

Example:

NOI:

$100,000

Loan:

$1,000,000

Debt Yield:

$100,000 ÷ $1,000,000 = 10%

One major advantage of debt yield is that it isn't directly changed by the loan's interest rate or amortization.

Loan-to-Value — LTV

What it means:The percentage of the property's value that is financed with debt.

Formula:LTV = Loan Amount ÷ Property Value

What it tells you:How leveraged the property is.

Who uses it:Lenders and investors.

Example:

Property value:

$1,000,000

Mortgage:

$750,000

LTV:

$750,000 ÷ $1,000,000 = 75%

That means the property is financed with approximately:

75% debt

and

25% equity

PITIA

PITIA stands for:

Principal, Interest, Taxes, Insurance, Association Dues

Formula:PITIA = Principal + Interest + Taxes + Insurance + Association Dues

What it tells you:The recurring monthly housing obligation being considered by the lender.

Who uses it:Primarily residential lenders and borrowers, especially in the United States.

Quick note:PITIA isn't really an investment return metric like IRR or CoC.

Think of it more as a total monthly debt-cost calculation.

Leverage Spread

What it means:A quick comparison between the return being produced by the property and the approximate cost of borrowing money.

A simplified version is:

Spread = Cap Rate − Cost of Debt

Example:

Property cap rate:

7%

Approximate cost of debt:

5%

Spread:

+2%

Generally, a positive spread means leverage may be working in the investor's favour.

A negative spread can mean the debt is costing more than the property's unlevered yield.

Who uses it:Investors, analysts and lenders.

Quick note:This is only a quick screening tool. Real leverage analysis also depends on amortization, loan fees, loan structure, changes in NOI and changes in property value.

4. VALUATION & COMPARISON

How does the price compare?

These metrics help you quickly compare a property with similar investment opportunities.

Gross Rent Multiplier — GRM

What it means:How much you are paying for the property relative to the gross rent it generates.

Formula:GRM = Property Price ÷ Annual Gross Rental Income

Example:

Property price:

$1,000,000

Annual gross rent:

$100,000

GRM:

$1,000,000 ÷ $100,000 = 10x

You're paying approximately 10 times the property's annual gross rent.

What it tells you:How expensive one property is relative to the gross rental income it produces.

Who uses it:Investors, brokers and appraisers.

Quick note:GRM completely ignores operating expenses.

That means two properties can have the same GRM while producing very different amounts of profit.

Price Per Unit — PPU

What it means:How much you're paying for each individual unit in a multifamily property.

Formula:Price Per Unit = Property Price ÷ Number of Units

Example:

Purchase price:

$2,000,000

Number of units:

20

Price per unit:

$2,000,000 ÷ 20 = $100,000/unit

What it tells you:How the property's pricing compares with similar multifamily properties.

Who uses it:Investors, brokers, appraisers and developers.

Quick note:Price per unit shouldn't be used alone.

A $100,000 unit renting for $1,800/month is very different from a $100,000 unit renting for $900/month.

THE BIG TAKEAWAY

You can simplify almost every real-estate metric into four questions:

THE PROPERTY

Is the building itself performing?

NOI, Cap Rate. OER

YOUR MONEY

Is my equity producing a good return?

Cash-on-Cash Return, IRR, Equity Multiple

THE LOAN

Can the property safely carry its financing?

DSCR, Debt Yield, LTV, PITIA, Leverage Spread

THE PRICE

How does this opportunity compare with others?

GRM, Price Per Unit

THERE IS NO SINGLE “BEST” METRIC

A property could have a great cap rate but poor cash-on-cash return because the financing is expensive.

It could have a great cash-on-cash return but weak DSCR because the investor is using aggressive leverage.

It could have a great IRR but very little annual cash flow because most of the projected return comes when the property is eventually sold.

That is why experienced investors don't rely on one number.

Each metric is a different lens on the same investment.

The goal isn't to find the perfect metric.

The goal is to understand what each number is telling you — and what it isn't.

These also aren't the "end-all, be-all" metrics for real estate. If you have a specific deal, send it to me and I can help you figure out what the best ways to measure the deal is.
