# Expense and margin benchmarks for Australian dental practices

Source: https://ivankamenken.com/benchmarks/general-dental-practices · By Ivanka Menken, Strategic Mentor · Last updated 21 October 2026

In the ATO 2023-24 small business benchmarks, Australian dental practices turning over more than $815,000 report total expenses of 67% to 80% of turnover. That leaves 20% to 33% of turnover before the owner, family members and tax are paid. The ATO open data does not publish a cost of sales ratio for this industry.

## What are the 2023-24 benchmarks for dental practices?

The ATO splits each industry into turnover bands and publishes a range for each. The band closest to a business turning over $500,000 to $3,000,000 is the high turnover range: more than $815,000. The figures in the text on this page come from that band, and the table shows every band the ATO publishes for dental practices.

A business turning over between $435,001 and $815,000 falls in the medium turnover range instead, and its figures are in the table too.

The ATO open data for this industry holds one ratio, total expenses to turnover, so this page works from that number. The ATO counts staff wages, rent, interest, depreciation and cost of sales inside total expenses, and leaves out payments to associated persons such as family members.

| Ratio, % of turnover | Low turnover range ($50,000 to $435,000) | Medium turnover range ($435,001 to $815,000) | High turnover range (More than $815,000) (closest to $500K to $3M) |
|---|---|---|---|
| Total expenses (ATO) | 55% to 67% | 65% to 73% | 67% to 80% |
| Left after total expenses (calculated) | 33% to 45% | 27% to 35% | 20% to 33% |

## What do these figures mean for cash and payroll in dental practices?

At the band’s ratios, a business turning over $1,000,000 would have $200,000 to $330,000 left after total expenses, about $3,850 to $6,350 a week. That pool has to cover your own pay, tax, loan repayments beyond the interest already counted, and any growth you fund yourself.

At the midpoint, dental practices keep 26.5% of turnover after total expenses, 12 points above the median of 14.5% across the 96 industries on this site. A wider share gives growth more room, but only if the cash arrives before the bills do.

Size changes the picture. Businesses in the low band ($50,000 to $435,000) keep 33% to 45% of turnover; in the band closest to you it is 20% to 33%. Part of the reason is in how the ATO counts: wages paid to staff are an expense, while payments to associated persons are left out. A bigger business carries a bigger payroll, so each extra dollar of turnover arrives with more cost attached.

## How much would a price rise change what dental practices keep?

Ivanka Menken’s chain starts with price: prices too low, margins thin, growth eats cash, payroll becomes a monthly fear. As arithmetic only, if dental practices in this band charged 5% more for the same work, with the same volume and the same costs, total expenses would fall to about 64% to 76% of turnover and the share left would rise from 20% to 33% to about 24% to 36%.

At the midpoint that is 26.5% becoming 30% of turnover, about 13% more left over from the same work. Whether your clients would accept the price is a separate question, and the one worth testing.

## Where do dental practices sit among Health Care and Social Assistance industries?

We grouped the ATO industries under their ANZSIC divisions so you can compare dental practices with their neighbours. Of the 5 Health Care and Social Assistance industries on this site, dental practices keep the 2nd largest share of turnover after total expenses, using each industry’s band closest to $500,000 to $3,000,000.

The grouping is ours, not the ATO’s; the ratios are the ATO’s. Neighbouring industries face similar costs, so a large gap to a close neighbour is worth a question about price or about the mix of work.

## How do you check your own numbers against these benchmarks?

Take last financial year’s turnover excluding GST, and total expenses less any payments to associated persons. Divide the second by the first and compare it with the 67% to 80% range above.

A benchmark tells you where you sit. It does not tell you why, or which decision to make next. Three free tools on this site turn the comparison into a monthly habit.

## Frequently asked questions

### What share of turnover do dental practices spend on expenses?

In the ATO 2023-24 benchmarks, dental practices turning over more than $815,000 report total expenses of 67% to 80% of turnover, leaving 20% to 33% before the owner, family members and tax are paid. Total expenses include staff wages, rent, interest and depreciation, and leave out payments to associated persons.

### Which ATO turnover band applies to dental practices turning over $1,000,000?

For dental practices, the ATO 2023-24 bands are: low turnover range, $50,000 to $435,000; medium turnover range, $435,001 to $815,000; high turnover range, more than $815,000. A business turning over $1,000,000 sits in the high turnover range. Use last year’s turnover excluding GST to find yours.

### Are the ATO figures before or after the owner’s pay?

Before most of it. The ATO subtracts payments to associated persons, such as family members, from total expenses, and a sole trader or partner does not pay themselves a wage at all. So the share left after total expenses is broadly what funds the owner, tax, loan repayments and growth. Your accountant can tell you how your own returns are set up.

### What does it mean if my business is outside the range?

The ATO says a business outside the key benchmark range may have room to improve, and it uses the key benchmark to spot businesses that may not be reporting all their income. Each range covers the 30% of businesses around the industry average, so many legitimate businesses sit outside it. Check your figures with your accountant first.
