Not every commercial property that looks profitable actually is. A busy plaza, a gas station with steady traffic, or a franchise unit with a full parking lot can all seem like a smart buy. But the only way to know for sure is to run the numbers.
That’s where ROI comes in.
Return on Investment (ROI) is a percentage that shows how much profit a property earns compared to how much money you put into it. It’s one of the first numbers any serious commercial real estate investor checks before making an offer.
In this guide, we’ll break down exactly how to calculate ROI on commercial real estate investments: the formulas, the methods, a real example, and the mistakes to avoid. Whether you’re eyeing a retail plaza, an office building, or a gas station in the GTA, the same core process applies.

What Is ROI in Commercial Real Estate?
ROI is the percentage of profit an investment generates relative to its cost. In simple terms: for every dollar you put into a property, how many cents (or dollars) come back to you?
It’s different from two other terms people often confuse it with:
- Profit is a dollar amount. ROI is a percentage.
- Cap rate looks only at the property’s income versus its value. ROI factors in your full investment, including financing.
ROI gives you a single, comparable number — which is exactly why it’s so widely used.
Why ROI Matters Before You Buy
Before you sign anything, ROI helps you answer the questions that actually matter:
- Compares properties: Puts two very different deals (say, a plaza vs. a gas station) on the same scale.
- Tracks performance: Shows whether a property is meeting the goals you set for it.
- Assesses risk vs. reward: A higher ROI often signals higher risk, not just a better deal.
- Guides financing strategy: Helps you decide whether to pay cash or use leverage.
- Sets realistic expectations: Keeps you from overpaying based on gut feeling alone.
Key Terms You Need to Know First
A few terms show up in almost every ROI conversation. Get comfortable with these first.
Net Operating Income (NOI)
NOI is what the property earns after operating expenses but before mortgage payments and taxes.
Formula: NOI = Gross Income − Operating Expenses
Example: A plaza earning $200,000 a year with $50,000 in expenses has an NOI of $150,000.
Total Investment
This is everything it actually costs you to own the property, not just the sticker price:
- Purchase price
- Closing costs
- Renovations and upgrades
- Legal and inspection fees
Cap Rate
Cap rate measures a property’s income against its value, without factoring in financing. It’s a quick way to compare properties on income alone, separate from how you paid for them.
The Basic ROI Formula
Here’s the core formula every commercial investor should know by heart:
ROI = (Net Operating Income ÷ Total Investment) × 100
- Net Operating Income: what the property earns after expenses
- Total Investment: everything you spent to acquire and prepare the property
- × 100: converts the result into a percentage
This is the “quick-check” version. For a fuller picture, most investors calculate ROI two different ways covered next.
Two Core Methods to Calculate ROI
The Cost Method
This method divides your equity in the property by the total cost of buying and owning it.
Best for: Buyers purchasing in cash, with no financing involved.
The Out-of-Pocket Method
This method divides your equity by the actual cash you spent — which matters a lot if you used a mortgage or commercial loan.
Best for: Buyers using leverage (financing).
Here’s the part that surprises a lot of first-time investors: a leveraged buyer often shows a higher ROI percentage than an all-cash buyer, even though the cash buyer earns more total profit. That’s because the leveraged buyer put in far less of their own money to get the deal done. Both numbers are useful; they just answer slightly different questions.
Step-by-Step Example Calculation
Let’s walk through a simple example using a small retail plaza in the GTA.
| Step | Detail | Amount |
| 1. Purchase price | Base cost of the property | $1,000,000 |
| 2. Closing costs + renovations | Added to purchase price | $100,000 |
| 3. Total investment | Step 1 + Step 2 | $1,100,000 |
| 4. Gross annual income | Rent from tenants | $180,000 |
| 5. Operating expenses | Taxes, insurance, maintenance | $60,000 |
| 6. NOI | Step 4 − Step 5 | $120,000 |
| 7. ROI | (Step 6 ÷ Step 3) × 100 | 10.9% |
In plain terms: for every dollar invested in this plaza, the owner earns roughly 11 cents back per year. Whether that’s a good number depends on the market and the risk involved — which we’ll cover shortly.
Other Metrics That Give ROI Context
ROI is powerful, but it shouldn’t be the only number you look at. Pair it with these:
- Cash-on-Cash Return: Annual pre-tax cash flow ÷ total cash invested × 100. Shows your yearly cash return specifically.
- Cap Rate: NOI ÷ property value. Useful for comparing income potential across properties.
- Internal Rate of Return (IRR): Accounts for the time value of money over your entire holding period, not just year one.
- Equity Multiple: Total cash received ÷ total equity invested. A 1.8x multiple means you got $1.80 back for every $1 in.
- Gross Rent Multiplier (GRM): Property price ÷ gross rental income. A fast, rough screening tool.
Each of these fills in a gap that ROI alone can’t cover together, they give you the full picture.
What’s a Good ROI on Commercial Real Estate?
A good ROI on commercial property typically falls somewhere between 8% and 12% annually, though this varies by market and property type.
- 8%–10% is common in stable, high-demand areas with lower risk, steadier income.
- 12% or higher often comes with more risk, such as higher vacancy or a less proven location.
In the GTA and across Ontario, property type matters a lot here. Gas stations, franchise units, and plazas each carry different risk-and-return profiles, so it’s worth benchmarking against similar properties in the same category, not just the market as a whole.
Factors That Affect Your ROI
A lot of moving parts shape your final ROI number:
- Location and market demand: Growing areas tend to support stronger long-term returns.
- Property type: Retail, industrial, office, franchise, and gas station properties all behave differently.
- Financing structure: Interest rates and loan terms directly affect your out-of-pocket ROI.
- Vacancy rates and tenant quality: Empty units or unreliable tenants quietly erode returns.
- Renovation and maintenance costs: Ongoing upkeep eats into NOI if it’s underestimated.
- Market timing and appreciation: Buying at the right point in a cycle can meaningfully boost returns.
- Property management efficiency: Well-run properties consistently outperform poorly managed ones.
Common ROI Mistakes to Avoid
Even experienced investors trip up here. Watch out for these:
- Ignoring vacancy costs —> Assuming 100% occupancy year-round is unrealistic.
- Leaving out closing costs —> Total investment isn’t just the purchase price.
- Relying on ROI alone —>Pair it with cap rate and cash flow before deciding.
- Using outdated comps —> Market conditions shift; last year’s numbers may not apply.
- Overestimating rental income — Be conservative, not optimistic.
- Forgetting property management costs —> Even self-managed properties have hidden time and cost factors.
Tools to Simplify Your ROI Calculation
You don’t need to run every formula by hand. A few resources make this easier:
- Simple spreadsheet templates for tracking NOI, expenses, and ROI over time

FAQs
What is a good ROI for commercial real estate?
Most commercial properties aim for 8%–12% annually. Lower returns tend to come with lower risk, while higher returns often signal more risk or a less established location.
How is ROI different from cap rate?
Cap rate measures a property’s income against its value alone. ROI factors in your entire investment, including financing so two properties with the same cap rate can have very different ROI.
What is the average ROI on commercial property in Ontario?
It varies by property type and location, but most stable commercial properties in Ontario fall within the 8%–12% range, with premium GTA locations often on the lower, steadier end.
Does ROI include mortgage payments?
The basic ROI formula uses NOI, which excludes mortgage payments. The out-of-pocket method, however, does factor in financing costs since it’s based on actual cash spent.
What’s the easiest way to calculate ROI quickly?
Divide your property’s Net Operating Income by your total investment, then multiply by 100. It’s a fast first check just to pair it with cap rate and cash-on-cash return for a fuller picture.
Is cash-on-cash return the same as ROI?
Not quite. Cash-on-cash return focuses specifically on your annual pre-tax cash flow relative to cash invested, while ROI can be measured a few different ways depending on the method used.
