How to work out my annual salary

[Comfysock]

So I want to know what my proforma based salary is based on i.e. what my salary would be if I worked full time
I work:

4 x days per week
7.5 hours a day
I have my gross pay.

What formula can I use to work out my annual salary not proforma salary if that makes sense!

Can you not just divide by 4 and times by 5

Do you mean pro rata?

What is "full time" where you work?

Divide by 4 gives you your daily salary
X5 gives you a week
X that by 52 for yearly
Divide that by 12 for monthly

Go to Listen to Tax Man website for an NI/Tax calculator to work out your net pay

This

Yes divide by four and times by five, if you mean pro rata. If full time is 37.5.

I found this pretty accurate.

Sorry just realised you are starting with just your annual gross.

Ok so annual gross is £20,000

Divide by 52 - weekly
Divide by 4 - daily

20000/52 = £384.62
384.62/4 = £96.15

Then you can work out what 5 days would be

96.15 x 5 = 480.77
480.77 x 52 = £25,000

OP isn’t asking about take home? Or are they?

UPDATE
I just want to know...
If I were to work say 5 days a week what my annual salary is before tax.

It stemmed from me and DH sorting a few financial things out and he ask me what I was on a year if I worked full.time e.g 5 days a week and I didnt know

This is the easiest way to do it. If you earn £25,000 working 4 days, you do £25,000 divided by 4 (which is £6,250). Multiply that by 5 to get your full time rate: £6,250 x 5 = £31,250. That's your full time salary.

Which is the same as dividing the annual salary by 4 and multiplying by 5 without all the long winded daily/ weekly calculations.

Thanks think Ive done it now
