02 / A REAL EXAMPLE

See what your readers get.

This is the actual commercial cleaning bid widget. Visitors can change their figures, reset the example and follow the complete explanation. The calculator is usable without buying anything.

We do not see or save values entered into the calculator. The optional resize script only receives the widget's height.

03 / TERMS

Simple to share. Fair to use.

You may embed the three publicly listed calculators on relevant educational, editorial and commercial pages at no charge. Please keep the calculator's visible Nihadium attribution, original links and context notes. Do not conceal or change the calculation, claim it is your own tool, or imply Nihadium endorses your services.

Visitors must decide whether their figures and assumptions are appropriate. Widgets are provided as educational calculators, not legal, tax, engineering or accounting advice.

04 / COOPERATION

Have a specific audience?

We can discuss a relevant resource placement or a transparent affiliate arrangement, but no commission or affiliate attribution applies until an agreement is made and tracking is configured in Gumroad. No affiliate program is represented as active here.

Describe the site and the audience you teach. We prefer small, genuine partnerships over mass promotion.
