Upgrading your account from one plan to another can sometimes be confusing, especially if you perform it mid way through a current plan. This article will walk through how the cost to change plans is calculated.

- The system calculates the time left in your current plan, as a fraction. (Tleft = [TCurrent – TEnd]/TLength)
- The system calculates the cost of the leftover time based on the amount you have already paid. ($Current = Tleft * $Paid)
- The system then calculates the price of the new plan. If you are changing your payment frequency, it calculates the new cost with the new discount amount. If you’re upgrading but not changing your payment frequency, it calculates this with the existing discounts. ($New)
- The system then deducts the amount you already paid from the amount for the new plan. ($New-$Current)

#### Example 1

A Church three months into their 12-month plan is upgrading from their 300 plan, to a 400 plan:

- Time remaining is 9 months, so the fraction would be 3/4.
- Their previous payment would have been $950.40 (including GST)
- Cost of remaining time would be $712.80
- The price of the new plan, for the remaining time with their current discount, would be $950.40.
- The price to upgrade for this church would be $237.6

#### Example 2

An Australian Church is three months into their plan and want to upgrade from a 200 plan to a 300 plan, and change their billing cycle from 6 monthly to 12 monthly.

- Time remaining is 3 months, so the fraction would be 1/2.
- Their previous payment would have been $356.40 inc GST.
- Cost of remaining time would be $178.20
- The price for the new plan would be $950.40
- The adjusted price $772.20
