A commercial loan is credit provided to a company, trust or other business structure to fund business activities such as property, equipment or working capital, not personal spending.

Also known as: commercial finance, commercial lending

Key points

  • Typical borrowers are companies, trusts and other business structures buying property, plant and machinery, or funding construction and seasonal gaps.
  • Structures range from long term loans secured by a mortgage to revolving overdrafts and short-term invoice finance.
  • Lenders commonly take a mortgage over property, a security interest over equipment perfected by PPSR registration, a general security agreement, and director personal guarantees.
  • Compare total cost, not the headline rate: establishment, valuation, legal and PPSR fees, plus covenants and break costs.

Frequently asked questions

What is the difference between a commercial loan and a business loan?

The labels overlap. Commercial loan usually describes larger, often secured lending to a business, especially where property or substantial assets are involved. Business loan is the broader term and takes in smaller facilities, including unsecured ones. The structure and security matter more than the label.

What security do lenders usually require for a commercial loan?

Commonly a mortgage over real property, a security interest over equipment and other chattels, perfected by registration on the PPSR, a general security agreement over company assets for corporate borrowers, and directors standing behind the debt personally. Unsecured facilities exist but are priced higher and carry tighter conditions.

Can a start-up get a commercial loan?

Yes, though the options are narrower and the terms tighter. Without a trading record, lenders lean on cash flow projections, the security you can offer and directors standing behind the debt. Some specialist lenders support newer businesses where mainstream lenders will not.

How does an interest-only period work?

You pay only the interest for an agreed window, so the principal does not reduce. Repayments are lower during that period, which helps cash flow, then they step up when principal repayments resume over the remaining term. Total interest paid is usually higher.

Are commercial loan interest payments tax deductible?

Interest on borrowing incurred in producing assessable income is generally deductible for a business. How much you can claim depends on how the funds are used and on your circumstances, so check the ATO's guidance or speak with your accountant.
