Hello,
Thank you for contacting Rank Math today,
You would only need to pay the differential amount, and not the full amount of the Business subscription based on the current market price.
This means that if you purchase the PRO plan now and wish to change to the Business plan after 6 months (assuming the price remains $199), you will only have to pay $100 (199/2 for half year) less $30 (59/2 for half year). If the price goes up, the upgrade price will go up as well.
I hope this information is helpful, and please do not hesitate to contact us if you require any additional support.
Thank you.
