How Our Calculators Work

Formula calculators

Formula calculators use direct arithmetic. Examples include ROAS (revenue divided by ad spend), conversion rate (conversions divided by visitors or clicks), work-hour totals and digital-product profit.

Scenario calculators

Scenario tools do not predict the future. They apply the assumptions you enter to a mathematical model. Where we provide convenience presets, those presets are labeled as scenarios rather than universal market benchmarks.

Taxes and changing rates

Tax calculators require periodic maintenance because laws, brackets, deductions, wage bases and local rules change. Pages that include tax estimates are labeled with the applicable year or date and explain major exclusions.

AI prices and platform economics

Where prices can change frequently, we prefer user-entered pricing rather than permanently hard-coding a provider price. This is why the AI Token Cost Calculator asks you to enter the current input and output token price.

Rounding

Display values are generally rounded for readability. Internal calculations may retain additional precision before the result is displayed.

Corrections and updates

If you identify a possible error, contact us with the calculator name, inputs and expected result. We review formula issues separately from differences caused by assumptions or external rules.
