Charge models
Graduated percentage
Select the graduated percentage model if you want to define several percentage tiers. You can also
apply a flat fee per tier in addition to the rate.
Note that the rate is the only mandatory value. It’s particularly useful for fintech charging graduated rates for a feature.
Consider the following example, where each unit represents an API call:
A first transaction at $500 would cost (500 units x 1%) + $200 flat fee = $205.00;
A second transaction at $550 would cost [(500 units x 1%) + (50 units x 2%)] + $300 flat fee = $306.00;
A third transaction at $4,000 would cost (4,000 x 2%) = $80.00.
| Tier | First unit | Last unit | Rate | Flat fee |
|---|---|---|---|---|
| Tier 1 | 0 | 1,000 | 1% | $200 |
| Tier 2 | 1,001 | 10,000 | 2% | $300 |
| Tier 3 | 10,001 | ∞ | 3% | $400 |
Unlike the fixed fee, the flat fee is applied to the entire tier, rather than per transaction.
