Properties to calculate the cost of a product or service.

Price Model

Basic pricing

In a basic price model, each unit of a product or service is assigned a fixed cost.

For example, consider a company offering cloud storage services at a rate of $0.5 per gigabyte (GB). In this scenario, the unit amount is set to $0.5, indicating that each GB costs $0.5.

For 10 units, 10 x 0.5(unit amount) = 5, $5 in total.

Tierd pricing

In tiered pricing, the cost of a given unit depends on the tier range that it falls into, defined by upper and lower bounds.

For example, the first 5 GB costs $0.5 each, 6-10 GB costs $0.3 each, and all subsequent GBs cost $0.2 each.

Tier Range (GB)	Price per GB ($)
1 - 5	$0.5
6 - 10	$0.3
11+	$0.2

For 4 units, 4 x 0.5 = 2, $2 in total.

For 8 units, 5 x 0.5 + 3 x 0.3 = 3.4, $3.4 in total.

For 15 units, 5 x 0.5 + 5 * 0.3 + 5 * 0.2 = 5, $5 in total.

Bulk pricing

In bulk pricing, units are billed in predefined bundles (bulk sizes).

For example, if the bulk size is 5, then 4 units will be billed as 5 and 6 units will be billed at 10.

For 4 units: 1 bulk x 5 (bulk amount) = $5, $5 in total.

For 6 units: 2 bulks x 5 (bulk amount) = $10, $10 in total.

Bulk Size	Bulk Amount
5	$5

Volume pricing

In volume pricing, the total number of units determines the cost per unit for all units.

For example, if you've bought 8 units, total price will be 8 x 0.5(unit price) + 5(flat fee) = 9, $9 in total.

Once you've bought more than 10 units, say 15 units, the total price will be 15 x 0.4(unit price) + 0.0(flat fee) = 6, $6 in total.

Number of Units	Price per Unit ($)	Flat Fee ($)
1 - 10	$0.50	$5.00
11+	$0.40	$0.00

Percentage pricing

Percentage pricing applies a per-event rate (e.g., per-payment) expressed as a percentage of the transaction value. For example, if the price is set as following

Percentage rate	Flat Fee ($)
0.25	$3.00

For a payment of $100, the charge will be 100 x 0.25(percentage rate) + 3(flat fee) = 27, $27 in total.

Tiered percentage pricing

Tiered percentage pricing applies when a per-event (e.g., per-payment) rate is expressed as a percentage of the transaction value with several tiers.

For example, if the price is set as following

Number of Units	Percentage rate	Flat Fee ($)
1 - 10	0.25	$3.00
11+	0.2	$1.00

For a payment of 9, the charge will be 9 x 0.25(percentage rate) + 3(flat fee) = 5.25, $5.25 in total.

For a payment of 20, the charge will be 10 x 0.25(percentage rate) + 3(flat fee) + 10 x 0.20(percentage rate) + 1(flat fee) = 8.5, $8.5 in total.

Matrix pricing

In matrix pricing, the cost depends on combinations of two or more properties.

For example, if the price is set as following

Property 1	Property 2	Price per Unit ($)
partner = aws	region = us-east-1	$0.5
partner = aws	region = us-west-1	$0.3
partner = gcp		$0.4

Default price: $0.2
