# Hourly pay - maths puzzle watch

1. Hi,

To calculate hourly pay, I have always thought it was annual salary/52 divided by number of hours contracted.

Howeve, the method my employer uses is

annual salary /12 = monthly pay.

Monthly pay divided by the number of days in the month i.e 31 days in october.

Then they, divide ithe daily pay by the number of hours worked.

This comes out at a much lower rate. I know this is wrong but can't see where the problems lies.

Dividing by the days in the month is a more accurate result since not every month has the same amount of days in them.

When you divide by 52 you automatically assume that every week's payment throughout the year is the same, hence every month's is the same, which is not the case. Hence you get more of an average, while the employer's is more accurate specific to the months and their weeks.

I have used the salary calculator and the figures by the two different methods vary considerabley. What should I do. I am being underpaid.
4. The problem is down to dividing it by the number of days in a month as you don't work 7 days a week so there aren't 31 working days in October.
5. So what is the correct calculation to do this? I don't know how to sort this big difference out with them?
