At this level, you're typically running a business with $100,000-$200,000+ in monthly revenue - construction firms, recruitment agencies, manufacturing businesses, large trade operations or multi-site hospitality groups.
Important: $150,000 is the threshold where most non-bank lenders begin requiring property security (a registered charge, not a full mortgage). However, some lenders on OverdraftMe's panel can approve up to $150,000 unsecured for very strong applications. We'll find the best option for your situation.
| Cost component | Bank | Non-bank |
|---|---|---|
| Interest rate | 8-14% p.a. | 12-26% p.a. |
| Establishment fee | $1,500-$4,500 | $1,500-$4,500 |
| Line fee (annual) | $1,500-$3,000 | $750-$3,000 |
| Interest on $150K drawn 30 days at 18% | - | $2,219 |
| Interest on $75K drawn 30 days at 18% | - | $1,110 |
At the $150,000 level, non-bank interest rates tend to be more competitive than at lower levels. Lenders compete more aggressively for larger facilities, and the property security (where required) reduces their risk - which translates to better rates for you.
A registered charge (also called a caveat or second mortgage) is not the same as a full mortgage. It's a security interest registered against your property that gives the lender priority in the event of default. You retain full use and ownership of the property - it simply means the lender has a claim if things go wrong.

Assumptions: 60% of the facility drawn and held constant (interest-only view), interest charged on the drawn balance, line fee of 0.046% per week on the full limit. Repaying the balance down adds principal on top of these figures - model a declining-balance schedule with the "Repay over term" view in the business overdraft calculator. Indicative only, subject to lender assessment - rates through the OverdraftMe panel run 14.55% to 25% p.a. See also the unsecured business overdraft guide.
$150,000 is the threshold where property security typically becomes a factor with non-bank lenders. Some lenders can approve $150,000 unsecured for very strong applications, but most will require a registered charge over property (not a full mortgage) at this level. OverdraftMe will find the best option for your situation.
If you draw the full $150,000 for 30 days at 18% p.a., the interest cost is approximately $2,219. Line fees are typically $1,500-$3,000 per year. Rates may be lower at this facility size as lenders compete for larger deals.
Most lenders require monthly revenue of $100,000-$150,000+ for a $150,000 facility. Lenders typically approve up to 1-1.5x your average monthly revenue.
