ROCE usually measures pre-tax operating profit against capital employed, while ROIC measures after-tax operating profit against invested capital. Work both from the same business-unit schedules and separate the tax effect from differences in the capital base.
ROCE vs ROIC is usually a comparison between pre-tax operating return on capital employed and after-tax operating return on invested capital. The tax treatment is only part of the difference: the two capital bases can include different balances. Put the formulas beside the percentages before comparing business units or deciding that one measure shows better performance.
For this comparison, use the following conventions:
ROCE = EBIT / Average capital employed.
Capital employed = Total assets - Current liabilities.
ROIC = NOPAT / Average invested capital.
NOPAT = EBIT × (1 - Approved operating tax rate).
ACCA's performance-analysis guidance presents ROCE using profit before interest and tax against long-term financing. The broader financial ratios guide gives the ROCE definition alongside other company measures; this page focuses on making the ROCE and ROIC pair comparable.
For ROIC here, invested capital equals capital employed less identified nonoperating cash. There is no short-term borrowing, no other nonoperating asset and no noncurrent liability other than debt in the example. These restrictions make the balance-sheet and financing approaches reconcile cleanly. They are assumptions to check in a real file, not rules that every company's statements satisfy.
Damodaran's financial definitions describe invested capital as book debt plus book equity less cash, paired with after-tax operating income. The lesson is to match the operating profit and asset scope. The detailed ROIC guide covers the denominator beyond this comparison.
| Basis | ROCE used here | ROIC used here |
|---|---|---|
| Profit numerator | EBIT, before financing and tax | NOPAT, after operating tax but before financing |
| Capital denominator | Assets less current liabilities | The same base less nonoperating cash |
| Balance convention | Opening and closing average | Opening and closing average |
| Main review question | How much pre-tax profit does capital support? | How much after-tax operating profit does operating capital support? |
An illustrative US manufacturer compares its Components and Assembly units over one fiscal year. Export the unit P&Ls and the opening and closing balance sheets. Retain account names, unit codes, balance dates and the mapping that distinguishes operating balances from financing and nonoperating cash.
Finance has approved a 25% operating tax assumption for both units. This is an illustrative combined assumption, not a federal statutory-rate claim. Neither unit has interest income in EBIT. All cash shown below is classified as nonoperating, and all current liabilities are non-interest-bearing operating balances.
| Balance-sheet row (USD) | Components opening | Components closing | Assembly opening | Assembly closing |
|---|---|---|---|---|
| Total assets | 10,000,000 | 12,000,000 | 8,000,000 | 8,000,000 |
| Current liabilities | 2,000,000 | 2,000,000 | 2,000,000 | 2,000,000 |
| Nonoperating cash included in assets | 1,000,000 | 1,000,000 | 0 | 0 |
| Long-term debt | 3,000,000 | 4,000,000 | 2,000,000 | 2,000,000 |
| Equity | 5,000,000 | 6,000,000 | 4,000,000 | 4,000,000 |
| Profit row (USD) | Components | Assembly |
|---|---|---|
| Annual EBIT | 1,200,000 | 900,000 |
| Operating tax at 25% | 300,000 | 225,000 |
| NOPAT: EBIT less operating tax | 900,000 | 675,000 |
Reconcile each unit's EBIT to its P&L before using either ratio. The tax adjustment is applied to operating profit, so it does not import the interest tax benefit or unrelated tax items from consolidated net income.
Components begins with capital employed of 10,000,000 - 2,000,000 = $8,000,000 and ends with 12,000,000 - 2,000,000 = $10,000,000. Its average is $9,000,000. Removing the nonoperating cash leaves invested capital of $7,000,000 opening and $9,000,000 closing, averaging $8,000,000.
Assembly has no excluded cash, so its capital employed and invested capital are both $6,000,000 throughout the year.
| Calculation | Components | Assembly |
|---|---|---|
| Average capital employed (USD) | (8,000,000 + 10,000,000) / 2 = 9,000,000 | (6,000,000 + 6,000,000) / 2 = 6,000,000 |
| Average invested capital (USD) | (7,000,000 + 9,000,000) / 2 = 8,000,000 | (6,000,000 + 6,000,000) / 2 = 6,000,000 |
| ROCE | 1,200,000 / 9,000,000 = 13.33% | 900,000 / 6,000,000 = 15.00% |
| ROIC | 900,000 / 8,000,000 = 11.25% | 675,000 / 6,000,000 = 11.25% |
Percentages are rounded to two decimal places; the calculations retain unrounded values. Assembly ranks higher on ROCE, but the units tie on ROIC under the stated definitions. Components carries nonoperating cash in its ROCE base, which changes that comparison.
This is why a column labeled simply "capital return" is insufficient. The formula and cash treatment determine what the ranking means.
First apply tax while holding Components' ROCE denominator fixed. Then change the denominator to invested capital.
| Components bridge | Calculation | Return |
|---|---|---|
| Pre-tax return on capital employed | 1,200,000 / 9,000,000 | 13.33% |
| After-tax return on the same capital | 900,000 / 9,000,000 | 10.00% |
| After-tax return on invested capital | 900,000 / 8,000,000 | 11.25% |
Multiplying ROCE by one minus the tax rate gets only to the middle row. It cannot remove cash from the denominator. Keep these adjustments separate so a tax effect does not get described as better asset productivity.
There is also a balance-sheet proof. For Components, opening debt plus equity is 3,000,000 + 5,000,000 = $8,000,000; closing debt plus equity is 4,000,000 + 6,000,000 = $10,000,000. Both equal assets less current liabilities. Subtracting the corresponding cash balances gives the invested-capital schedule above. Assembly's corresponding check is 2,000,000 + 4,000,000 = $6,000,000 at both dates.
Use ROCE for an operating review that explicitly tracks pre-tax profit against the approved capital-employed definition. It can help unit managers discuss profit delivery and asset utilization without starting with different tax assumptions. The separate ROCE DuPont formula splits that return into margin and turnover.
Use ROIC when the review needs after-tax operating performance on the capital invested in operations. If comparing returns with a capital-cost hurdle, align tax treatment and the capital scope first. A headline ROCE percentage is not automatically a spread over an after-tax financing cost.
Finance owns the definitions, tax policy and reconciliation. Unit managers own explanations for operating changes; treasury can validate financing and nonoperating cash classifications. A stable written mapping makes the next quarter comparable.

No. Tax generally reduces the ROIC numerator, but excluding cash or other nonoperating assets can reduce its denominator. The net result depends on both adjustments. Some companies also use a different definition of ROCE, so read the stated formula before comparing the percentages.
Only if both measures use exactly the same capital base and operating scope. That multiplication gives an after-tax return on the ROCE denominator. If invested capital excludes balances retained in capital employed, you must also rebuild and average the invested-capital denominator.
Choose a policy that matches the profit period and apply it consistently. Average opening and closing balances is a practical starting point. Monthly averages can better reflect large acquisitions, seasonal balances or midyear investments. Label the method and preserve the underlying balance dates.
