Free Tool for Property Owners
Do you know what your rental property is actually earning?
Most property owners track rent. Very few track return. The Asset Performance Calculator shows you your cap rate, NOI, and adjusted cash flow — so you know whether your property is building your wealth or quietly eroding it.
See your cap rate based on today's market value — not your original purchase price
Calculate NOI after taxes, insurance, management fees, and vacancy loss
Factor in reserves for repairs and unexpected costs — so you see real returns
Find out whether your equity is working or just sitting
Know the truth before you make a decision that affects your family's wealth
No spreadsheets. No guesswork. Get the calculator, plus a quick guide to interpreting your results.

The rent comes in every month. Expenses feel manageable. So everything seems fine.
"Fine" is not a measurement. Without one, you cannot know whether your property is building your wealth or quietly eroding it.
Net Operating Income
Start with your gross rental income. Subtract taxes, insurance, maintenance, management fees, and vacancy loss. What remains is the actual income your property generates. Most owners have never calculated this number.
Cap Rate
Take your NOI and divide it by your property's current market value — not what you paid for it. This single percentage tells you your real return on equity. A property earning 1.9% in a 2% inflation environment is not breaking even. It is losing ground.
Adjusted Cash Flow
Cash flow after expenses looks better than it is until you account for vacancy, capital expenditure reserves, and real carrying costs. Adjusted cash flow is what you actually keep. That is the number that determines whether holding this property still makes sense.
How it works
From raw numbers to clear decisions in three steps.
The Asset Performance Calculator is built for busy rental owners who want clarity, not complexity. You don’t need a finance degree or a 20‑tab spreadsheet to use it.
Step 1: Input your numbers. Enter each property’s purchase price, current value, rent, and key expenses.
Step 2: See your real return. The calculator shows your NOI, cap rate, and adjusted cash flow instantly — no spreadsheet required.
Step 3: Make a clear decision. Hold, reposition, or plan your exit with numbers, not assumptions.
You’ll also get a simple cheat sheet explaining what “good” looks like for typical rentals, so you can benchmark each asset with confidence.
A peek inside the calculator
Here’s an example of the kind of clarity you’ll see for each property:
You’ll be able to run this same view for every property you own, side by side.
Who it’s for
If this sounds like you, the calculator will pay for itself quickly.
The Asset Performance Calculator is ideal for rental owners who:
Own between 2 and 50 doors and want a simple way to see portfolio‑level performance.
Are wondering, “Should I sell this one and trade up?” but don’t have clear numbers to decide.
Suspect some properties are carrying more risk than reward, but can’t pinpoint which ones.
Are planning rent increases, renovations, or refinances and want to model the impact.
Want a repeatable process you can run quarterly to keep every asset accountable.
If you’re tired of trusting your gut and want data you can actually act on, this is built for you.

"Many property owners discover that what they thought was a strong performer has actually been underperforming for years. And what surprises most people is that the so-called 'safe' choice — keeping the property — often turns out to be the riskiest one of all."
