Search "capitalisation rate" and you get finance definitions and agency glossaries that stop at a formula. Useful maths. Incomplete for buyers. A Cap rate is only as honest as the income you put into it. Cap face rent or unrecovered gross income and you capitalise marketing. Cap day-one net operating income and you capitalise cash you can defend.
This is the buyer read on capitalisation rate for commercial property in Australia. Commercial passing rent vs net income covers flyer rent versus true net after outgoings. Gross lease vs net lease and how to calculate WALE cover recovery and term. Commercial property due diligence keeps the lease-first order. Here I stay on one teaching point: what Cap rate means when you are the buyer, and what to verify before you trust a marketed number.
What capitalisation rate is (buyer formula)
In Australian commercial practice, capitalisation rate (Cap rate) is the rate used to convert annual net income into capital value. The Property Council of Australia (PCA) glossary puts it as a divisor that converts income into value: property value estimate equals net operating income divided by the capitalisation rate. Rearranged for a purchase screen: Cap rate equals net operating income divided by purchase price (or agreed value).
In buyer language:
Cap rate = day-one net operating income ÷ purchase price
Or solve for price:
Indicative value = day-one NOI ÷ Cap rate you are willing to pay
That is Method teaching of the arithmetic, not a promise that the flyer already used that NOI. Cromwell Funds Management, citing the PCA definition, walks the same equation: annual NOI over value. Their article also flags a buyer trap I see constantly: marketed Cap maths often sit on face rent NOI, while incentives and ongoing capital expenditure sit outside the simple Cap story.
Finance costs and income tax sit outside NOI for this Cap conversation. You are grading the property's operating income quality first. Debt and tax sit in your personal structure after that.
Face rent, passing rent, and the income input Cap needs
Cap rate is not a personality trait of the suburb. It is a ratio. Change the numerator and the "same" Cap tells a different story.
Keep the income labels straight before anyone argues rate:
- Face rent is the contractual rent written in the lease.
- Passing rent is the current rent spoken for across the roll. Useful for screening. Still not Cap-ready if outgoings, vacancy, or incentives are unresolved.
- Effective income strips or spreads incentives so you are not capitalising rent-free months or fit-out contributions as if they were permanent cash.
- Day-one NOI is verified income after landlord-retained outgoings and an honest vacancy treatment. That is the Cap input that survives settlement.
I do not rebuild the full passing rent vs net income piece here. Point is narrower: if the agent Cap'd face rent or gross passing rent, the Cap rate on the flyer is not the Cap rate you should underwrite.
Incentives move the numerator. Outgoings recovery and vacancy move the numerator too. Purchase price (or the price you are about to offer) is the denominator. Soft recovery, soft occupancy, or a soft incentive schedule means you either cut the income you Cap, raise the Cap rate you demand, or both.
Why advertised yield is not a clean Cap rate
Australian commercial marketing mixes "yield", "net yield", and "Cap rate" in the same brochure. Buyers hear them as synonyms. They are not always the same job.
- Yield in flyer language is often rent (sometimes "net") divided by asking price. Ask which rent, which costs, and whether vacant suites were excluded.
- Cap rate in valuation and agency research language is the rate applied to (or implied by) net income to support value. PCA treats Cap rate as the conversion rate between net income and capital value.
- Implied Cap after a sale is NOI over the price actually paid. That is a transaction readout, not a free pass to Cap the next asset on the same number without rebuilding income.
If the pack cannot say whether the quoted percentage is on face rent, passing rent, effective rent, or true net after recoveries, you are not ready to Cap. Triple net lease Australia already warns that marketing shorthand is not a recovery map. Cap language has the same honesty test.
What higher and lower Cap rates are signalling
I do not publish invented Australian Cap tables or "typical" sector averages here. Markets move. Asset class, location depth, covenant, lease quality, and recovery quality move with them. Qualitative signals buyers should still read:
Lower Cap (higher price for the same NOI) usually prices stronger income quality or stronger buyer competition for that income: better location depth, stronger covenant, cleaner net recovery, longer firm term, lower near-term vacancy risk.
Higher Cap (lower price for the same NOI) usually prices more risk or less competition: shorter firm term, softer covenant, weaker recovery, secondary location, asset type that needs more reletting or capex work, or income that is harder to defend.
None of that is a rule that "higher Cap is bad". Sometimes a higher Cap is the correct price for a harder income spine. The buyer error is treating a high flyer Cap as a bargain when the NOI in the flyer is soft. Cap and income quality move together inside The Deal Grade™: letter A to C on the building, number 1 to 3 on the income. Cap rate sits after that grade, not instead of it.
Vacancy, outgoings, and incentives: high-level Cap movers
Three inputs move Cap honesty without needing a standalone outgoings essay:
1. Vacancy. Income Cap'd as if the asset is full when suites are empty (or soft) overstates NOI. Ask how vacant area was treated in the flyer percentage.
2. Outgoings recovery. Landlord-retained rates, insurance, land tax allocation, or management cost compress day-one NOI. Map that with gross lease vs net lease. Do not Cap "net" marketing until the schedule and actuals agree.
3. Incentives. Rent-free periods and fit-out contributions reduce cash income across the firm term. Cromwell notes that face rent is typically the NOI unit used in Cap presentations, while incentives sit beside that story. As a buyer, Cap the income you can bank, not the face figure used to win the tenant.
Keep how to calculate WALE beside Cap. Term risk and income risk are different axes. A clean Cap on a soft near-term expiry is still a fuse.
Buyer checklist before you trust a marketed Cap rate
Before you attach a Cap rate to an offer:
1. Rebuild annual rent from the executed leases and variations, not the brochure summary.
2. Confirm face versus effective treatment of incentives, rent-free months, and fit-out contributions still running or unpaid.
3. Map recoverable versus landlord-retained outgoings suite by suite, with budget and 12 to 24 months of actuals.
4. State vacancy treatment in the flyer Cap: included, excluded, or assumed stabilised.
5. Rebuild WALE to firm expiry with options listed separately.
6. Ask which income unit the marketed Cap or yield uses: face, passing, "net", or true day-one NOI.
7. Only then Cap true net against the Cap rate that fits your buy zone and the graded income quality.
If the selling agent cannot answer those from the pack, treat the Cap claim as provisional. Price the risk or walk. Formal legal and valuation work stay with your solicitor and valuer. My job is to make sure the commercial Cap question is asked before emotional capital is spent on the tour.
What a commercial buyers agent does is forcing that rebuild on your side of the table.
Next step: Ready Check / go-commercial
If you are graduating from residential into commercial income assets, start with capital, income need, and risk posture on the Commercial Ready Check. Process and commercial representation sit via go-commercial. Site CTA is Book a strategy call.
Bring the rent roll, outgoings pack, and any Cap or yield schedule the agent used. If you do not have them, that is the first gap we close before anyone talks Cap rate.
Frequently asked questions
What is capitalisation rate on commercial property?
Capitalisation rate is the rate that converts annual net operating income into capital value (or, reversed, NOI divided by price). PCA frames it as the divisor used to capitalise net income into value. Buyers should Cap day-one true net, not brochure face rent.
Is Cap rate the same as yield?
Not always. Flyer "yield" is often a marketing percentage on a rent figure that may ignore unrecovered outgoings, vacancy, or incentives. Cap rate, used properly, is the conversion rate between verified net income and value. Ask which income unit sits under the percentage you are being sold.
Why can two Cap rates on the same building look different?
Because the numerator changed. Cap on face or passing rent is not Cap on true net after landlord-retained outgoings and incentive adjustments. Same asset. Different offer number.
Does a higher Cap rate mean a better buy?
Not by itself. A higher Cap often prices higher risk: lease quality, location, recovery, vacancy, or asset type. A lower Cap often prices stronger income quality or stronger competition. Grade the income first, then decide whether the Cap fits that grade.
What should I verify before I trust a marketed Cap rate?
Lease-backed rent, incentive treatment, outgoings recovery and actuals, vacancy treatment, firm-term WALE, and a plain answer on which income unit the Cap uses. Then Cap true net. The lease-first sequence sits in commercial property due diligence.
