Stripe Sigma pricing
Stripe Sigma’s monthly price is based on components of your monthly processing activity. To calculate processing activity, we add the total number of charges, authorization requests , and application fees your business processed in the billing month.
You can see what will be counted as processing activity based on the Stripe products your business uses.
We calculate your Stripe Sigma price based on the graduated tiers in the table below. For example, the price for your first 500 processed activities is $.02 per processed activity, and the price for your next 500 is $.018 per processed activity.
We also charge a monthly infrastructure fee based on your total processing activity for the month. In other words, if your processing activity total for the month is between 1,001 and 5,000 processed activities, your infrastructure fee is the fee for up to 5000 transactions ($50/month).
If your business creates 600 charges and 200 authorization requests in March (total processing activity = 800), $40.40 would be deducted from your settlement funds in April for your use of Stripe Sigma in March.
Once you’ve activated your subscription, we will deduct the Stripe Sigma fee from your Stripe balance at the beginning of each month based on the prior month’s processing activity. If you activate mid-month, your first month’s processing activity will only include processing from the date of activation until the end of the month. You can cancel your subscription at any time, but your subscription will remain active until the end of the month in which you cancel; and fees for that month will still be collected.
 Authorizations that are later captured are not counted again for your processing activity.
