When you upgrade your account we will calculate a charge. This article tries to explain how this price is calculated. We have tried to make the pricing model as fair as possible.
The price is calculated in the following way:
We determine what the cost of your new plan will be. For example 50 students on a Pro plan is 50 x $5 / year = $250 / year.
We determine any discounts, for example if you have remaining time on your trial, if you have previously downgraded or if you are upgrading from an existing paid plan.
We subtract the discount from the cost of your new plan to determine the final price.
Reach out on support if you have any questions about the cost of your plan.
