Ontario Cap Rate Calculator 2025: How to Analyze Your Investment Like a Pro

In This Article:
If you’re a real estate investor in Ontario, understanding how to evaluate your property’s performance is essential. That’s where our Ontario cap rate calculator 2025 comes in.
Cap rate — short for capitalization rate — is one of the simplest, yet most powerful tools landlords and investors use to assess whether a rental property is financially worth it. And if you want to make smart, data-backed decisions this year, knowing your property’s cap rate is a great place to start.
What Is a Cap Rate?
A capitalization rate (cap rate) is a formula used to estimate the potential return on a real estate investment. It’s calculated by dividing your property’s net operating income (NOI) by the purchase price.
Cap Rate = Net Operating Income ÷ Property Value
Think of it as your property’s ROI (return on investment), expressed as a percentage. The higher the cap rate, the higher the potential return — but often, the higher the risk.
Why Do Investors Use Cap Rate?
Cap rate is popular for good reason. It’s easy to calculate and compare across multiple properties. Unlike cash flow, it ignores mortgage financing and focuses purely on the property’s performance.
- Compare properties in different cities or price brackets
- Set target returns
- Evaluate long-term rental potential
- Understand local market trends (high cap rate = riskier, low cap rate = stable)

Ontario Market Comparison (2025 Example)
Let’s say you’re looking at three properties this year:
Location | Monthly Rent | Purchase Price | Estimated Cap Rate |
---|---|---|---|
Belleville | $1,800 | $420,000 | 5.1% |
Toronto | $2,300 | $750,000 | 3.2% |
Ottawa | $2,100 | $600,000 | 4.0% |
While Toronto offers higher rents, Belleville may give you a better return. That’s the power of cap rate — it helps you cut through price tags and focus on income performance.

4 Cap Rate Tips for Smarter Investing
