5% is commonly cited as a 'good' return on assets, a rule of thumb investors use to judge how efficiently a company turns assets into net profit. That 5% figure appears in guides such as Canstar, while other investor sites explain ROA and stress industry differences, so treat it as a starting point rather than a pass-fail threshold. Sector norms matter: banks, miners and utilities carry large asset bases so their ROAs look very different to software and finance firms. For you, treat ROA as a quick efficiency filter on ASX names before deeper due diligence.
5% is useful for spotting efficiency, but only when you calculate it the right way and compare like with like.
1. Calculate the ratio
1. The formula is simple: ROA = net income divided by total assets, expressed as a percentage. That definition is used by Investopedia, Canstar, Swoop and iTiger.
2. Net income is the bottom-line profit on the income statement after costs, interest and taxes. Total assets are the sum of short-term and long-term assets on the balance sheet.
3. Many practitioners use average total assets for the period, adding beginning and ending total assets and dividing by two, to avoid distortion from seasonal or one-off swings. Investopedia follows this convention in its worked ExxonMobil example, which shows how very large asset bases can make strong absolute profits translate to modest ROA percentages.
2. Choose the income measure and compare like with like
1. Standard ROA uses net income, but some analysts calculate a variant with operating profit, or EBIT, to focus on operating performance before financing and tax.
Be explicit which numerator you use and why, because the two measures tell different stories.
2. ROA using net income captures non-operating items and financing effects. Swoop and iTiger point out that ROA doesn't reflect capital structure, so two firms with the same assets can show different net-income ROA if one is more highly geared.
3. Compare a company to its industry peers and to its own history. Canstar states that 5% is generally good and 20% is great, but warns that capital-intensive sectors such as mining, utilities and transport typically report much lower ROAs than software or financials. Cockatoo uses Australian examples to make this concrete: a large bank can report what sounds like a low ROA, for example Commonwealth Bank of Australia at roughly 1.2 percent in recent half-year results, and that figure is meaningful within banking. By contrast, Fortescue's mid-single-digit to high-single-digit ROA is notable in mining.
4. Look at multi-period trends. An improving ROA over several periods can signal better asset utilisation or rising profitability. A declining ROA can signal large asset investments that haven't yet produced returns, or other structural changes to the business.
3. Practical adjustments and what to watch in 2026
1. Use average assets for year-over-year comparisons. When a company revalues assets or completes a major acquisition, annotate the calculation and consider a pro forma adjustment so periods are comparable.
2. If you want an operating view, compute ROA with EBIT and adjust net income for non-recurring items where relevant. Depreciation policies, one-off gains or losses, and accounting conventions for asset valuation can materially change ROA without an underlying operational shift.
3. Cockatoo highlights that policy changes and the interest-rate environment in 2026 can temporarily depress ROA for companies that add assets financed at higher costs. Use ROA alongside return on equity and return on invested capital to separate operating efficiency from financing effects.
4. Express ROA as a percentage to make cross-company comparison straightforward. Annotate your calculations and be explicit about any adjustments or alternate numerators so readers or colleagues can reproduce your work.
5. Treat ROA as a first-pass efficiency filter when screening ASX stocks, then drill into sector norms and company notes before making a decision. It points you to candidates that deserve deeper analysis, not to a final buy or sell call.

Next step: find the company's net income on the income statement and total assets on the balance sheet, compute ROA using average total assets, and compare that percentage with the industry peer group and the company's multi-year trend to decide whether the ratio shows operational improvement or is driven by accounting or financing effects.
