How Internal Rate of Return (IRR) Helps You Measure Property Performance
Article Summary
- Internal rate of return (IRR) measures the effective annual return on a property by weighing all cash inflows and outflows over time.
- IRR helps you evaluate how efficiently your capital grows by including both ongoing income and the property's sale proceeds.
- Cap rate and cash-on-cash return show short-term performance, while IRR captures the long-term impact of timing and growth.
- Key drivers of IRR include the timing of cash flows, financing structure, and exit value, since small shifts can change results dramatically.
What Is Internal Rate of Return (IRR)?
Internal rate of return (IRR) is the annualised rate of growth an investment is expected to generate based on its projected cash flows and eventual sale.
If you're just getting started, think of IRR as the annual “growth rate” your property would earn if everything goes according to plan. When you're comparing multiple properties or portfolios, it's a reliable way to evaluate deals of different sizes, timelines, and risk levels because it accounts for when money moves in and out.
Every investor wants their capital to work efficiently. Knowing your IRR shows how effectively each dollar you invest is performing and whether a deal is truly building your wealth.
Many investors use IRR alongside other metrics like cap rate and cash-on-cash return. It simplifies complex projections in commercial real estate investing into a single annualised percentage that's easy to compare.
Why IRR Matters for Investors
IRR gives you a comprehensive view of your property's performance and allows you to make smarter, more confident investment decisions.
Understanding internal rate of return allows you to measure how time and cash flow interact to shape returns. It helps you assess opportunities more confidently across different hold periods and investment types.
As your portfolio grows, it refines how you gauge risk and long-term performance across markets. Think of it as your time-weighted lens on performance. Pair it with net present value (NPV), cash-on-cash return, and risk metrics to make smart, data-backed decisions that stand the test of time.
Used well, IRR turns uncertainty into clarity and helps you make faster, more informed investment choices.
How Do You Calculate IRR for a Commercial Property?
Start by listing every cash flow from purchase to sale, then find the rate of return that brings them all to today's value.
To calculate IRR, list your expected cash flows, including what you invest upfront as negative cash flow, what you expect to earn each year, and what you expect to receive when you sell.
Here's the breakdown:
- Estimate your initial equity investment (negative cash flow at year zero).
- Forecast annual net cash flows from operations (income minus expenses minus capital expenditures). Your net operating income (NOI) drives this figure.
- Estimate the sale or refinance proceeds at exit (positive cash flow at the end).
The internal rate of return represents the discount rate that makes the total present value of all future cash flows equal your initial investment. In simpler terms, it's the annualised return that balances what you put in with what you expect to get back over time.
IRR Formula
In plain English:
0 = Sum of [Cash flow in period t ÷ (1 + IRR)^t] - Initial investment
In mathematical notation:
Where:
- CFₜ = Cash flow in period t (the net income after expenses in each year)
- t = Time period (0, 1, 2, 3... representing each year)
- IRR = The internal rate of return you're solving for
- Initial investment = Your upfront equity
Getting this right gives you more than a number. It gives you a clear sense of whether your investment is truly building long-term wealth.
Tip for investors: Model your cash flows carefully. Account for when property taxes, utilities, and lease-up costs (the dollars to attract and sign tenants until stabilized) actually occur, and use reliable local market data when estimating your exit cap rate.

How IRR Works in a Real Estate Investment Example
Two five-year scenarios show how earlier cash flows and different exits can flip the winning deal.
IRR can look simple on paper, but the timing of your cash flow changes everything. The two examples below show how the same investment amount can produce very different returns depending on when cash flows arrive.
Scenario A
- Equity invested: $1,000,000 (year 0)
- Years 1 to 4 cash flow: $80,000 each
- Year 5 cash flow: $80,000 + sale proceeds $1,200,000
- IRR ≈ 11.2% (illustrative)
Scenario B
- Same $1,000,000 equity
- Years 1 to 4 cash flow: $60,000 each
- Year 5 cash flow: $60,000 + sale $1,300,000
- IRR ≈ 10.8% despite the higher sale price, because earlier returns were smaller
The takeaway: stronger early cash flow often produces a higher IRR, even if the final sale price is lower.
This example shows why cash flow timing matters and why IRR works best when you model both timing and scale together.
How Is IRR Different from Cap Rate and Cash-on-Cash Return?
Cap rate and cash-on-cash return look at a moment in time, while IRR captures the full investment journey.
While cap rate and cash-on-cash return offer quick snapshots, they only show how a property performs at one point in time. IRR, on the other hand, captures the full investment journey by accounting for both timing and growth in cash flow.
That perspective matters most when you plan to hold a property for several years. Two assets can show identical cap rates today, but the one that generates stronger or earlier cash flow will usually achieve a higher IRR overall.
For example, two retail properties for sale in Vancouver might start with the same cap rate. The one with earlier lease renewals and steadier rent growth will likely deliver better returns when measured through IRR. This simple difference shows why investors use IRR to evaluate a property's performance over time, not just its starting yield.
What Can Impact Your IRR the Most?
The timing of cash flows, the exit value, and capital spend are the biggest drivers.
Here's how each one can influence your returns:
- Timing of cash flows: Faster lease-up or early rent growth improves IRR.
- Exit value: Selling at a tighter cap rate or higher price increases IRR.
- Capital spend: Major renovations, tenant improvements, or long vacancy periods reduce IRR.
How you finance a property can have just as much of an impact. A building with healthy coverage ratios and conservative leverage will usually produce steadier long-term returns. If you're exploring financing options, check how your debt service coverage ratio (DSCR) could influence your loan terms and leverage.
IRR also varies by asset class. If you were comparing office properties for sale in Calgary, you might need to expect longer lease-up times than industrial or retail buildings, which affects early cash flow.
When money moves, even small shifts can change the story of an entire investment. That's why investors treat IRR as both a scorecard and a guide to how each decision shapes long-term value.
What Are the Limitations of Internal Rate of Return?
IRR doesn't account for risk, reinvestment assumptions, or uneven cash flow patterns.
Like any financial tool, IRR works best when you know what it can and can't tell you. Keep in mind:
- It assumes interim cash flows are reinvested at the same IRR, which isn't always realistic.
- Unusual cash flow patterns can create more than one IRR.
- IRR measures efficiency, not size. A 20% IRR on $100,000 isn't the same as 20% on $10 million.
If you're still building experience, treat IRR as a useful guide, not the full story. Once you're analyzing more advanced deals, always look at IRR alongside NPV, equity multiple, and hold period to understand both efficiency and scale.
Used wisely, IRR deepens your analysis and helps you see the bigger picture. This is especially true for land for sale, where cash flows may be limited until development begins, making IRR less predictive on its own.
What Does a “Good” IRR Look Like in Commercial Real Estate?
A “good” IRR depends on your strategy, leverage, and level of risk.
There's no universal benchmark, but you can set a personal target based on your goals and how actively you plan to manage the asset. Stabilized core properties often deliver returns in the high single digits, while value-add or development projects aim higher to balance greater uncertainty.
If you use financing, your target IRR should be higher, since leverage amplifies both upside and downside results.
The key is to use IRR as a compass, not a finish line. It helps you align deals with your financial goals and risk tolerance so you can make informed, confident decisions over time.

Frequently Asked Questions
Should I always pick the deal with the higher IRR?
Not always. A higher IRR can come with more risk or a shorter hold period, so it's important to look at the full picture. Use IRR alongside metrics like cap rate and cash-on-cash return to understand how the deal performs under different assumptions.
Does leverage increase IRR?
Usually, yes. When borrowing costs are lower than your property's return, leverage can lift IRR, but it also increases exposure to risk. Always model different loan scenarios to see how financing terms affect both returns and resilience.
Can IRR be negative?
Yes. If the total discounted cash flows are less than your initial investment, the IRR will be negative. This typically happens when income falls short or expenses rise faster than expected, so tracking performance early can help you course-correct.
How often should I update IRR?
Review your IRR annually or whenever rents, expenses, or financing terms change significantly. Regular updates help you spot shifts in performance early and keep your investment plan aligned with your long-term goals.
