Something like this?
ContractProduct.objects.filter(contract__id=X,
product__id=Y).values_list('rebate_pct', flat=True)
or if you already have a contract:
contract.products.filter(product__id=Y).values_list('rebate_pct', flat=True)
or product:
product.contractproduct_set.filter(contract__id=Y).values_list('rebate_pct',
flat=True)
