Commercial Property Borrowing Power Calculator

See how much you could borrow to buy a warehouse, depot, office or shop, and the cash you’ll need to settle.

The property

If GST applies, you pay it at settlement and a GST-registered buyer claims it back on the next BAS.
Business income
Use your EBITDA from your latest financials. Add back any rent you currently pay for these premises, since you won’t pay it once you own them.
Include truck, equipment and business loans, and car leases.
Lender settings (you can change these)
Banks usually lend up to 70% for commercial property; some non-bank lenders go to 80%. Lenders test your income at a rate above the actual rate and want it to cover the repayments with room to spare.

Check your options

How this calculator works. Your indicative maximum loan is the lower of two limits. The first is the loan-to-value ratio (LVR) applied to the purchase price, excluding any GST. The second is what your income can service. For an investment or SMSF property, that’s the net rent divided by the interest cover required and the assessment rate (interest rate plus buffer). For your own premises, it’s your business profit less existing repayments, divided by the debt cover required, and applied to principal and interest repayments over the loan term at the assessment rate. Repayments shown use the interest rate you enter.

What it doesn’t cover. Each lender has its own policy on LVR, income, cover ratios, industries, property types and locations. Specialised properties such as service stations or childcare centres usually have lower LVRs. SMSF loans have extra requirements, including cash the fund must keep after settlement. Rates change often; the Reserve Bank next meets on 29 September 2026.

Stamp duty. The calculator uses each state’s general transfer duty rates for commercial property for 2026–27, applied to the GST-inclusive price. It doesn’t include foreign purchaser surcharges, concessions or exemptions. Sources: Revenue NSW, SRO Victoria, QRO, RevenueWA, RevenueSA, SRO Tasmania, ACT Revenue Office and NT Treasury. Confirm the final amount with your conveyancer.
