Stepped (group target) rebates¶
A stepped rebate pays a rate that depends on how much turnover the whole group does. The element carries a table of bands (steps) — a from-figure, to-figure, and rate per band — and the group's combined turnover for the period decides which band applies to everyone.
How it calculates¶
- Each period, the engine totals the group's turnover on the element's input stream.
- It selects the band whose from-figure is the highest one at or below that total. Turnover below the lowest band pays nothing.
- The selected rate is applied to each member's own rebateable (output-stream) turnover.
Example. Bands: £0–100k → 1%, £100k–250k → 1.5%, £250k+ → 2%. The group does £180,000 in the period, so the 1.5% band is selected. A member who did £20,000 of that receives £300 (£20,000 × 1.5%) — the group's level sets the rate, the member's own turnover sets the amount.
By default banding is retrospective: the selected rate applies to all rebateable turnover, so crossing a band boundary uplifts everything. A non-retrospective element instead applies each band's rate only to the turnover inside that band (marginal, like income tax) and shares the banded total between members pro-rata by their share of group spend.
A linear element does not jump between rates at the boundary: the rate is interpolated between the current band and the next according to how far through the gap the group's turnover sits.
Why does a stepped rebate change unexpectedly?¶
- The group crossed a band boundary — on a retrospective element this re-rates the entire period's turnover, so the jump can be large.
- Another member's turnover arrived. A member's own figures being unchanged does not mean their rebate is stable: the group level picks the band.
- The element is also growth/catch-up/strung/compound — see those pages; modifiers combine.
What a stepped rebate is not¶
- It is not an individual target rebate — there, each member's own turnover picks their band, and one member's performance never affects another's rate.
- It is not a growth rebate — bands here are absolute turnover values, not growth percentages.
