A sibling discount rewards families who bring more than one child, and it fills spots. It also costs you money on every family that would have come anyway. Design it on purpose.

### Percent or flat amount
A percentage off scales with the price: it is simple to state and fair across programs of different prices. A flat amount off is easier to budget, because you know exactly what each extra child costs you.

Example: on a $300 week, 10% off the second child is $30. A flat $25 off is close, and it stays $25 when a cheaper half-day program is involved.

### Which child gets the discount
- Apply it to the second and later children, not the first.
- Apply it to the lower-priced registration, so the discount isn't larger than the program it sits on.
- Decide whether children in different programs count as siblings (a camper and an after-school child, for example).
- Decide whether the discount applies only when the children register at the same time, or whenever they are enrolled in the same season.

### How it combines with other discounts
Write down the order: does the sibling discount apply before or after early-bird pricing, a multi-week discount or a scholarship? Stacking every discount can bring a price below your cost per child. A common rule is that scholarships replace other discounts rather than add to them.

### Work out what it costs
Multiply the discount by the number of siblings you expect, based on last year. Our [sibling discount calculator](https://backpr.com/tools/sibling-discount-calculator) does the math, and the [camp budget calculator](https://backpr.com/tools/camp-budget-calculator) shows whether your price still covers costs.

### Explain it in one sentence
Put the rule on the program page and show the discount in the cart before payment, for example: "Second and later children save 10% on each week." Families should never discover a discount only on the receipt.

### How BackPR helps
BackPR applies sibling discounts, multi-week and multi-program discounts, early-bird pricing, coupon codes and scholarships automatically in a multi-child checkout, and shows the family the result before they pay. See [payment features](https://backpr.com/features/payments).
