The short version
- As a rule of thumb, non-bank lenders lend an unsecured amount of roughly 50% to 100% of your average monthly revenue, so a business turning over $50,000 a month can often borrow $25,000 to $50,000 unsecured, and more with a strong history.
- Security changes everything. With property behind the loan, the ceiling is set by the asset's value, not by a revenue multiple, so it can be far higher.
- Longer trading history, clean statements and low existing debt raise your ceiling. Short history, messy statements and existing facilities lower it.
- The amount you can borrow and the amount you can comfortably repay are different numbers. Lenders check the first; you live with the second.
- These are rules of thumb. Your real number depends on your lender, profile and security.
"How much can I borrow for a business loan?" has a real answer, and it's more predictable than most owners expect. Lenders don't pluck a number out of the air. They run a rough serviceability calculation off your revenue, then adjust it up or down for history, security and existing debt. Once you know the formula, you can estimate your own ceiling before you ever apply.
This guide gives you the rule-of-thumb formula, a borrowing-power table by turnover, the factors that move your ceiling in each direction, and a worked example of what the repayments actually look like.
The rule-of-thumb formula
For an unsecured business loan, most non-bank lenders start from your average monthly revenue and lend a fraction or multiple of it. A common baseline is:
Unsecured borrowing ≈ 50% to 100% of your average monthly revenue.
So a business averaging $50,000 a month in revenue can typically access around $25,000 to $50,000 unsecured as a starting point. A strong, established business with clean statements can push toward one to two months of revenue; a newer or patchier one sits at the lower end. It's a starting estimate, not a promise, but it's close enough to plan around.
Secured lending works on a completely different basis. When there's property or another asset behind the loan, the ceiling is driven by the value of that asset and the lender's loan-to-value ratio, not by a revenue multiple. That's why security can lift what you can borrow well beyond anything revenue alone would support.
Borrowing power by turnover
Use this as a rough calculator. Find your average monthly revenue, read across.
| Average monthly revenue | Typical unsecured range | With security |
|---|---|---|
| $20,000 | ~$10,000 - $20,000 | Driven by asset value, often much higher |
| $50,000 | ~$25,000 - $50,000 | Driven by asset value, often much higher |
| $100,000 | ~$50,000 - $100,000 | Driven by asset value, often much higher |
| $250,000 | ~$125,000 - $250,000 | Driven by asset value, often much higher |
Two things to read into that table. First, the unsecured column scales directly with revenue, because revenue is what services the loan. Second, the secured column deliberately doesn't give a number, because it isn't set by your revenue, it's set by how much equity sits in the asset you're offering. A business with modest revenue but real property equity can borrow far more secured than unsecured.
What raises your ceiling
These push your borrowing capacity up:
- Longer trading history. Two years reads very differently from six months.
- Clean bank statements. No dishonours, no gambling, a balance that doesn't live at zero.
- Security. Property or a substantial asset lifts the ceiling above any revenue multiple.
- Strong, consistent revenue. Steady beats spiky, even at the same annual total.
- Low existing debt. Room to service more.
- GST registration and a solid credit file. Both signal scale and reliability.
What lowers it
These pull it down:
- Short trading history. The single biggest limiter for newer businesses.
- Existing loans and facilities. Current repayments are subtracted from what you can service.
- Seasonal or declining revenue. Lenders lean on your weaker months, not your best.
- Messy statements. They cap the amount before they cap the rate.
- A higher-risk industry or credit blemishes. Both narrow the panel and trim the ceiling.
Most of these are the same factors that decide whether you qualify at all, covered in full in business loan requirements.
The amount you can borrow and the amount you can comfortably service are different numbers. Lenders check the first. You live with the second. It's easy to treat an approval for $100,000 as advice that $100,000 is sensible, it isn't. The lender is confirming you can probably repay it. Whether you should carry that repayment through a slow month is a question only your cash flow can answer.
Five real scenarios
The $20k-a-month cafe. Averaging $20,000 a month, no property. Realistically borrows $10,000 to $20,000 unsecured, enough for a small equipment purchase or a short cash-flow bridge, not a major expansion.
The $50k-a-month trades business. $50,000 a month, 18 months trading, clean statements. Sits comfortably in the $25,000 to $50,000 unsecured range, toward the top of it given the clean history.
The property-backed wholesaler. Only $40,000 a month in revenue, but $400,000 of equity in a commercial premises. Unsecured, it's capped around $40,000. Secured against the property, it can borrow several times that, because the asset, not the revenue, sets the ceiling.
The business with an existing loan. $80,000 a month, but already repaying a facility. The existing repayment is subtracted from serviceability, so the new ceiling is lower than the revenue alone would suggest. Sometimes consolidating first frees up more capacity than borrowing again.
The seasonal landscaper. $60,000 a month across three quarters, near zero in winter. Lenders average it out and weight the quiet period, so the ceiling reflects the annualised figure rather than the peak months.
What the repayments actually look like
Knowing what you can borrow is only half of it. What matters is the repayment.
As an illustration, a $100,000 unsecured loan over two years, at an indicative rate, might run somewhere around $4,500 to $5,000 a month, for a total repaid of roughly $110,000 to $120,000. Change the term and the numbers move: stretch it to three years and the monthly repayment drops but the total interest rises; shorten it and the reverse. Your actual figures depend on the rate your profile attracts.
Before you borrow to your ceiling, work out the repayment as a share of your revenue, and test it against your quietest recent month. If it's comfortable in a good month and painful in a slow one, borrow less. And compare offers on total repayment and the effective annual rate, not the headline rate, two loans of the same size can cost very different amounts.
What you need to qualify
The borrowing ceiling assumes you meet the basics: an active ABN, around six or more months of trading, consistent revenue, and clean recent bank statements for a non-bank lender. Banks ask for two years plus financials and often security, but in return can lend larger secured amounts. The full process of getting a loan walks through it, and working out what you actually need stops you borrowing to the ceiling out of habit.
For a quick estimate: unsecured, expect around half to one month of your revenue as a starting point, more with a strong history. Secured, the asset sets the ceiling, not the revenue. Then borrow the amount the job needs, not the amount you're approved for.
Common questions
How much can I borrow with $50,000 monthly turnover?
As a rule of thumb, roughly $25,000 to $50,000 unsecured, scaling toward $100,000 with a strong trading history and clean statements. With property or another asset as security, you can borrow considerably more, because the loan is then sized against the asset's value rather than a revenue multiple.
How is business loan borrowing capacity calculated?
For unsecured lending, lenders start from your average monthly revenue and lend a fraction or multiple of it, then subtract your existing debt repayments and adjust for trading history, industry and statement quality. For secured lending, capacity is driven by the value of the asset offered and the lender's loan-to-value ratio.
Can I borrow more with property security?
Usually, yes, often substantially more. Security lowers the lender's risk, so the ceiling shifts from a revenue multiple to the value of the asset. A business with modest revenue but real equity in property can borrow far more secured than it ever could unsecured, and typically at a lower rate too.
Do lenders count all my revenue?
Not always at face value. Lenders look for consistent, genuine trading revenue, so one-off spikes, inter-account transfers and irregular income are often discounted. Seasonal businesses are usually assessed on an averaged or annualised figure rather than their best month, which is why steady revenue supports more borrowing than spiky revenue at the same total.
What repayments would a $100,000 business loan have?
As an illustration, roughly $4,500 to $5,000 a month over two years, for a total of around $110,000 to $120,000 repaid, depending on the rate and any fees. A longer term lowers the monthly figure but raises the total cost. Always confirm the exact repayment and the effective annual rate before committing.
