What changed
  • Fee calculator redrawn so the answer — what you'd pay — leads, not a small line in a table
  • Three steps: set account size, pick a scenario or fine-tune the return, read the result
  • Figures are VAT-inclusive examples you choose, not a forecast of what the software will make

The pricing calculator on the homepage works out what the software's fee would be for an account size and a monthly return you choose. The layout has been redrawn around one idea: the answer — what you would pay — should be the biggest, clearest thing on the card, not a small line in a table underneath the inputs. These are examples you choose, not a forecast: the calculator only shows how the fee would work out for the month you pick, and says nothing about what the software will actually make.

How to use it

  1. Set your account size. Type a number, drag the slider, use the plus and minus steppers either side of the figure, or tap a preset — €2,500, €7,500 or €10,000. €2,500 is the minimum the slider will travel to.
  2. Choose a starting point for the month, or skip straight to fine-tuning. Four scenario cards — “The last 31 days”, “A quiet month”, “A strong month” and “A losing month” — each move the return slider to a fixed value.
  3. Fine-tune the return by dragging the slider yourself, anywhere from −5% to +15%.
  4. Read the answer on the right: what you would pay today, and the ongoing monthly basis underneath it.

What you would pay, in plain terms

The figure shown first is a one-time fee: paid once, to activate the software, and nothing renews on its own after that. From the first month on, you are invoiced in arrears on the profit the software actually made that month — with a fixed €25 minimum on any profitable month, and nothing at all on a month with no profit.

What the calculator will not do

It will not quote you a return. Where there is no live trailing figure to show — for example, before an account has a month of history — the slider starts at 0% and a note underneath says plainly that no return is being quoted; it shows only the minimum, which applies whatever the month does. The calculator is there to show how the fee is worked out, not to forecast what any account will make.

A note on the figures

The four scenario cards are starting points for exploring the mechanic, not a promise about any particular month. The “last 31 days” card uses a live, trailing figure across real-money accounts when one is available, and is disabled with “No trading data yet” when it is not.

All prices on the calculator are VAT-inclusive: the figure shown is the total you would pay, with Belgian VAT already contained in it rather than added afterwards.

The timeline underneath the answer

Below the headline figure sits a short timeline spelling out the billing model in plain terms, directly on the card rather than only in fine print underneath it: Today, when the software activates; End of month 1, when your first invoice is worked out on that month’s profit; and Every month after, where you are billed on the profit actually made, subject to the same €25 minimum on a profitable month and nothing on a month that made none. A short “How it's worked out” control expands the underlying arithmetic for anyone who wants to see the calculation itself rather than only the result.

Before and after

The previous version buried the answer as the third row of a breakdown table, smaller on screen than the account-size field above it — so the number a visitor actually came to see was the least prominent thing on the card. It now leads the output column, at a size that matches its importance.
