Can I pass the transaction charges to my customers?

At the moment, Paystack does not allow merchants to automatically pass transaction charges to customers.  Since we do not offer this feature, this is something you (the merchant) will have to achieve on your end. You can use a formula to include our charges in the final amount you charge your customer.

How do I calculate the final amount to include Paystack's transaction fees?

This varies based on the amount being charged and the transaction fees of your country. For certain transactions, there are flat fees as well as percentage fees so we would provide a formula for percentage fees and another for percentage fees + flat fees. To know what pricing applies to you please read: What are Paystack's transaction charges? 

I'm being charged a percentage fee only

Here is the formula that applies to you:

Final Amount = {Price} / (1 – {Decimal Fee})

I'm being charged a percentage fee and flat fee

Here is the formula that applies to you: 

Final Amount = ({Price} + {Flat fee}) / (1 – {Decimal Fee})

•  Final Amount - This is the gross amount you pass to your customer which would include our transaction fees. This is the amount they will actually be paying.
• Price - This is how much you will receive after we deduct our transaction fees. This is the amount you want to collect from your customers.
• Decimal Fee - This is our percentage transaction fee converted to decimals. To calculate this simply divide the fee that applies to you by 100. So if the transaction fee for your country is 1.95%, your decimal fee is 0.0195.
• Flat fee - This is the flat fee we charge based on our pricing.
