The growth rebate: rewarding a supplier’s year-over-year progress
A growth rebate rewards year-over-year progress on top of the base rebate: what it is computed on, tiers by amount or percentage, common pitfalls and examples.
7 min readUpdated
A growth rebate is an additional scale on top of the year-end rebate that rewards year-over-year growth in turnover. Its tier is determined by the change against the previous year, in euros or as a percentage; with a whole rate, the rate reached then applies to the year’s total turnover. Well designed, it steers the relationship towards growth; poorly defined, it becomes the first source of year-end disputes.
What is a growth rebate?
The base rebate scale rewards a level of turnover. A growth rebate rewards movement: the supplier pays an extra percentage if the turnover achieved with the distributor grows enough compared with the previous year. It comes on top of the base scale and any family scales; it does not replace them.
A supplier whose volume is flat can therefore reach a high tier of the base scale without earning any growth rebate, while a small, fast-growing supplier can earn a growth rebate while staying in a low tier of the base scale.
What is a growth rebate calculated on?
Two quantities are involved and must be kept apart:
- The change, which determines the tier reached: as an amount, year N turnover minus year N-1 turnover; as a percentage, that difference divided by year N-1 turnover.
- The base, to which the rate applies: with a whole rate, it is year N’s total turnover; with a marginal rate, it is the slices of the change itself.
Bonus = year N turnover × rate of the tier reached by (N − N-1)
Worked example
Take a growth rebate defined on the change in euros:
| Change against N-1 | Rate |
|---|---|
| Decline (below €0) | 0% |
| €0 to €100,000 | 0% |
| €100,000 to €300,000 | 0.5% |
| €300,000 and above | 1% |
Example
€1,000,000 of turnover in N-1, €1,250,000 in N
The change is +€250,000 (+25%). It lies between €100,000 and €300,000, so the tier reached is 0.5%.
- With a whole rate: €1,250,000 × 0.5% = €6,250.
- With a marginal rate, on slices of the change: the first €100,000 of growth at 0%, the next €150,000 at 0.5%, or €750.
Depending on growth, the bonus moves as follows:
| Year N turnover | Change | Whole rate | Marginal rate |
|---|---|---|---|
| €900,000 | −€100,000 | €0 | €0 |
| €1,050,000 | +€50,000 | €0 | €0 |
| €1,150,000 | +€150,000 | €5,750 | €250 |
| €1,250,000 | +€250,000 | €6,250 | €750 |
| €1,400,000 | +€400,000 | €14,000 | €2,000 |
The gap between the two modes is even wider than for the base scale: in marginal mode the bonus only applies to the growth, not to all turnover. The bonus is added to the base rebate: in our full rebate calculation example, it brings the total to €38,250.
Tiers by amount or by percentage?
Tiers can be expressed in euros of growth or as a percentage of growth. With a percentage scale, for example 0% below +10%, 0.5% from +10% to +20% and 1% above, the same +25% growth reaches the 1% tier: €1,250,000 × 1% = €12,500.
| Tiers by amount | Tiers by percentage | |
|---|---|---|
| Measures | Euros gained over N-1 | Percentage growth |
| Suited to | Suppliers of known, stable size | Comparing suppliers of different sizes |
| Weak point | Needs recalibrating when size changes | A small supplier grows fast in percentage terms |
| Marginal rate | Possible, on slices of the change | Not applicable: a slice of a percentage is not an amount |
| Zero prior year | All business counts as growth | Change cannot be computed |
Small or large supplier: the same scale says different things
Compare two suppliers under the two growth scales in this article, with a whole rate: by amount (0.5% from +€100,000 to +€300,000, 1% above) and by percentage (0.5% from +10% to +20%, 1% above).
| Supplier | N-1 → N | Growth | Amount scale | Percentage scale |
|---|---|---|---|---|
| Small | €200,000 → €260,000 | +€60,000 (+30%) | €0 (0% tier) | 1% × €260,000 = €2,600 |
| Large | €2,000,000 → €2,200,000 | +€200,000 (+10%) | 0.5% × €2,200,000 = €11,000 | 0.5% × €2,200,000 = €11,000 |
The small supplier grows strongly in percentage terms but not in amount: it earns nothing under the euro scale and the top rate under the percentage scale. The large supplier earns the same under both. Neither is better in absolute terms: an amount scale rewards volume won, a percentage scale rewards momentum whatever the size. Choose based on what you want to encourage.
Combining a growth rebate with the base scale
A growth rebate is never read on its own. With our example base scale (2% between €1M and €2M), two suppliers at €1,250,000 of turnover earn the same base rebate, €25,000. If one was already at €1,250,000 the year before and the other at €1,000,000, only the second earns the €6,250 growth rebate: €31,250 in total against €25,000.
That is the intended effect: at the same level, growth is rewarded. But adding the two scales can also create a double threshold effect, when growth crosses a growth bound just as the total crosses a base-scale bound. Simulate the combinations before signing.
Tracking growth during the year
During the year, compare year N’s validated cumulative figure with N-1’s at the same date. If the supplier is at €610,000 at the end of June against €488,000 a year earlier, it is up €122,000, or +25%. With a landing of €1,250,000 it would finish at +€250,000, in the 0.5% tier: a €6,250 bonus.
The distance to the next growth tier is then €50,000: at €1,300,000 of turnover, growth would reach +€300,000 and the rate 1%, a €13,000 bonus, while the base scale would stay at 2% (€26,000). Those extra €50,000 of turnover would bring €7,750 more rebate in total, €6,750 of it from growth: the kind of information that steers fourth-quarter purchasing.
Pitfalls to avoid
- A missing prior-year figure. Without validated turnover for the previous year, the bonus cannot be computed. Counting it as zero would turn all turnover into growth.
- A changing scope. An acquisition, a new store, delisted or added products change growth without any commercial effort. Define the comparison scope in the agreement.
- Different periods. During the year, compare cumulative figures to the same month for N and N-1, even if the period split has changed.
- The threshold effect. With a whole rate, crossing +€100,000 takes the bonus from €0 to about 0.5% of all turnover: accurate declarations around that threshold are essential.
- Decline. An explicit 0% “decline” band makes the rule clear: no bonus, but no penalty on the base scale either.
When should you offer a growth rebate?
- To support a new supplier’s ramp-up.
- To back a range extension or a wider listing.
- To develop a strategic category, combined with a family scale.
- Less so for a mature, stable relationship, where a well-calibrated base scale is enough (see designing next year’s scale).
Growth rebates in Palier
In Palier, the growth bonus is an optional scale of the agreement. Its tiers apply to the change in euros or as a percentage, with an explicit decline band; the whole or marginal mode is set separately, marginal being available for amount-based tiers only. The prior year’s figure comes from the previous year’s last validated period or from imported history; if it is missing, the bonus is flagged as not computable instead of being computed on zero. See the features.
Key takeaways
Frequently asked questions
How is a growth rebate calculated?
Compute the change in turnover against the previous year, find the tier that change reaches, then apply its rate to the year’s total turnover with a whole rate, or to slices of the change with a marginal rate.
Does a growth rebate replace the year-end rebate?
No, it comes on top. The base scale rewards a level of turnover; the growth rebate rewards progress from one year to the next.
Should growth tiers be in euros or in percent?
Tiers in euros suit suppliers of stable size and allow a marginal rate; percentage tiers make suppliers of different sizes comparable, but favour small volumes.
What happens if turnover declines?
A negative change falls into a 0% band: no growth rebate. The base scale still applies as usual.
What if the previous year’s turnover is unknown?
The growth rebate then cannot be computed. It should not be computed as if the previous year were zero, which would count all turnover as growth.
