What's my full time salary?

[headscratcher]

Have worked 4 days a week for the past few years and recently realised I have no idea what the non-pro-rata equivalent would be.

I earn £2100 a month before tax for the 4 days a week - how do I work out what the gross salary is if I were to go full-time?

Divide by 4 then multiply by 5

How many hours is full time and how many hours do you do over 4 days?

Thesalarycalculator website is more accurate but yes divide by 4 times 5 is the calculation

I make it £31,500 as you are currently earning 4/5ths of your full time salary

£2100 /0.8 = £2625 I think.

You work 80% so

X * 0.8 = your salary hence X = your salary / 0.8 = full time wage

You're all brilliant and patient – this is exactly what I thought... and then I looked at my payslip and started wondering about taxes and talked myself into thinking it was more complicated than that

@PontiacBandit I looked at the salary calculator website and it's great, but it only seemed to calculate what the pro rata version of a salary was, not the other way around.

Thanks so much all of you for not laughing at my confusion!

I’d say it’s a rough estimate . Pension and or student loans are a proportion of your salary so that could make a slight difference .

You're overthinking it if you're struggling with converting 4 days per week to 5 days per week as it's exactly the simple calculation that it would appears to be.

However, the affect on your take home pay is not so straightforward due to tax allowances and how NI is deducted. But there are plenty of online calculators that will work this out for you.

Your gross annual salary will go up proportionately, but unfortunately your take home pay does not. You may also wish to take into account the cost of an extra day's commuting, lunch, childcare etc if relevant.
