Short story is we use a 28 day month to day calculation that is rounded to a 3 decimal multiplied to 7 and then rounded to 2 decimals. But let’s break down what that actually means. To figure out our pricing our system holds values based on a 28 day calculation, for example our disk is stored as 0.0015. This will get multiplied to the disk used in MB, and then divided by 28 making the pricing down to a per day price. This can be seen in some places on the panel like in a containers billing area. We do this to more fairly round up and down depending on usage. After this is done a cost for storage might look like 731 MB disk multiplied by 0.0015 making it 1.0965 and we divide that by 28 making it 0.03916071429. Since this does not work as a billing amount we round to 3 decimals making it 0.039 and multiply by 7 giving us a weekly price of 0.273. We add up all values in this calculation before rounding for databases, disk, backups, plugins and more. One final step is to round to 2 decimals before charge, so in this case it would be a cost of $0.27 for 731 MB of disk space every week. This may appear to be complicated but it allows the system to always provide the most even fair cost on all services since it’s bundled and rounded together allowing them to balance each-other out. Just as often as it results in a rounding up by a penny it rounds down by a penny, and by adding everything up before we round up we calculate the lowest cost every time compared to a separate calculation. This is why on our container billing page we show Disk, Database, Backups and Plugins rounded to the 3 decimal place as it’s not accurate until calculated together.
