Formula and methodology
Formula: Effective tax rate = income-tax expense or benefit ÷ pre-tax income × 100.
The effective rate summarizes the relationship between reported tax expense or benefit and pre-tax income for the entered scope. It is an accounting ratio and should not be confused with a statutory rate, marginal rate, or country-specific tax liability.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Pre-tax income — currency; minimum -1000000000000000000; maximum 1000000000000000000
- Income-tax expense or benefit — currency; minimum -1000000000000000000; maximum 1000000000000000000
Worked example
| Input | Value |
|---|---|
| Pre-tax income | 150000 |
| Income-tax expense or benefit | 30000 |
Effective corporate tax rate = 20%, with after-tax income of 120,000.
Assumptions and limits
- Pre-tax income and tax expense or benefit cover the same reporting period and continuing scope.
- Pre-tax income cannot be zero because the ratio would be undefined.
- Negative income or a tax benefit can produce unusual or negative effective rates that require statement-level interpretation.
- Tax filing rules, deferred-tax classification, loss carryforwards, credits, and local legislation are not calculated.
