About DailyUseKit

Our purpose

DailyUseKit helps people work through everyday price and profit questions with simple tools that run in a browser. It is designed for shoppers and small sellers who want to see both a result and the arithmetic behind it.

How we explain calculations

Each calculator states its inputs, formula, worked example and limitations. Guides use currency-neutral examples so readers can apply the arithmetic in their own currency. Examples are illustrations, not claims about typical earnings or local prices.

Scope and updates

The current tools cover selling price, unit-price comparison and daily business profit. We review the explanations alongside calculation changes. We do not supply live exchange rates, country-specific taxes, accounting services or earnings guarantees.

Corrections

If a result appears wrong, check the units, percentage meaning and included costs first. A direct support channel has not yet been published. See the Contact page for current support availability.
