Reducing hours- how to work out new take home pay

[yorkshapudding]

I currently work 5 days a week term time only. I would like to drop a day so that I can take my DD to school and pick her up one day a week and to catch up on housework etc.

So am I right in thinking that if I went from doing 5 days a week to 4 my take home pay would be 80% of what I currently get? So if I currently take home £20k a year I would drop to £16k.
DH reckons I would take home a bit more than 80% because tax, NI etc would go down but neither of us really knows.

Is there a way to find out exactly what my take home pay would be if I reduced my hours?

Sorry if this is a stupid question. Maths really isn't my strong point.

Try an online calculator. Should be accurate.

Find a pay slip.
Check your gross and multiple by 0.8.
Put details into m.thesalarycalculator.co.uk

There’s a website, google “salary calculator”

I am sure I responded to this yesterday - have you posted the same post again?

Anyway look at www.salarybot.co.uk

Apologies, must have posted again by accident. Not sure how that happened. Will ask for it to be deleted.

Haha not to worry I wondered if I was imagining things! Xx

There is no better place to break-down your salary and visually represent your take-home pay than this tax calculator . It's highly interactive and helps you see the tax and NI bands like no other tax calculator. I hope it helps ;)
