How to calculate subscription amount for paypal

And after i want to inject this amount in paypal subscription option.

Hello rudyrudy,

Unfortunately it is currently not possible to achieve your requirement.

Please be noted that calculated amount can only be passed to payment question if you have set it to as "Collect Donations/Custom Amount Payments". It will always be a one time payment.

Calculated amount/ custom payment cannot be used for recurring or subscription payments. You will actually have to add the subscription products in your PayPal payment question with fixed price. 

Hope this answers your query.

Do get back to us if you have any questions.

Thank you!
