Hi @KUBE
When you say that you can’t work out the maths, what part would you like clarification on?
With Affinity, accounts are calculated on a daily basis and then billed monthly. There’s more information on account sizes and how they’re calculated here.
To calculate the rate of an account per day, take a look at the Affinity Price Calculator here
I hope that helps, but please let me know if you have any further queries. You’re also welcome to send me a private message (click my name and then ‘Message’) should you wish to discuss account specific queries.
