1. If you have less than or equal with 365  remaining days for the Standard Subscription, the finish date is calculated with the following formula:

RemaingCost = 70 – [(70/365) * RemainingDays]

DaysToAdd = RemainingCost / (199.99 / 365)

FinishDate = OldFinishDate + DaysToAdd

Example

You have 1 Standard Subscription that expires after 50 days on 10/25/2019

RemainingCost = 70 – [(70 / 365)  *  50] = 60.41

DaysToAdd  = 60.41 / 0.5479 = 110 days

FinishDate = 10/25/2019 + 110 days = 2/12/2020

2. If you have greater than 365 remaining days for the Standard Subscription, the finish date is calculated with the following formula:

TotalRemainigCost = [RemainingDays * (129.99 / 365)] + 70

DaysToAdd = TotalRemainingCost / (199.99 / 365)

FinishDate = CurrentDate + DaysToAdd

Example

You have 1 Standard Subscription that expires after 700 days on 9/24/2020

RemainingCost = [700 * (129.99 / 365)]+ 70= 319.29

DaysToAdd  = 319.29 / 0.5479 = 583 days

FinishDate = 10/25/2018 + 583 days = 5/29/2020
