Calculate instead of guessing

24 calculators and reference works from daily business. No sign-up, and apart from the map lookup in the CO₂e calculator everything runs in the browser — nothing is sent.

Explainer · about 30 secondsWhy a calculator is more than a number

    A quote names a price. One number is hard to negotiate over.

    What am I entitled to?

    Waiting time, a standing container, cabotage, driving hours — four entitlements that get lost in daily business because someone would have to do the arithmetic. That is what these tools do.

    How much fits?

    Loading metres, volumetric weight and the points rule for dangerous goods. Three calculations that decide whether a load travels as planned.

    A calculator replaces no judgement. It makes sure people argue about one number rather than about two different ones.

    Where the best solution sits today

    What is named is the pattern, not the vendor — a product name ages, an idea does not.

    Rebuild the other side’s calculation

    Comparing the price means negotiating over one number. Rebuilding the calculation behind it means negotiating over the items — that is where the room is.

    Make comparable before comparing

    Headline price, tolls, diesel surcharge, waiting time, payment terms: only added up are two quotes the same thing.

    Measured beats calculated

    A measured distance is evidenced, an estimated one has to say so. The difference shows up at the first dispute.
