Calculz / practical tools

Make the number useful.

Calculators for fees, profit, rates, and the everyday decisions that need a clear answer.

A small working set

Tools that earn their place.

Each one shows the inputs, assumptions, and result so you can decide what to do next.

Estimate fees, payout, profit, and margin before you list.

Turn your target income into a rate that accounts for real working time.

Compare campaign cost, impressions, and the price of reach.

Calculz is built for the part after the spreadsheet. Enter a few real numbers, check the assumptions, and leave with an answer you can use.

There is no account to create and no black box hidden behind a result.

Start with a real listing

Estimate what a sale leaves behind before you spend time photographing, packing, and listing it.
