why is salary calculator giving me a take home calculation much lower than my actual take home?

Does this website give accurate take home pay calculations?  My actual monthly take home pay is £200 higher than what this calculator suggests it should be and I’m worried my employer is calculating it wrong and I would owe a lot of tax at the end of the year. Can starting a new job 1 month after April  (I.e. in May) cause this? I can’t figure it out - I’ve put in all the pensions, benefits etc.

There are numerous such calculators but they should all give reasonably accurate outputs that reflect the quality of the inputs (it's not rocket science) - if you share all the relevant figures (including cumulatives, tax codes, etc) then no doubt they can be verified....

I have used this calculator a lot over the last couple of years, due to job changes and pay rises. It's always been correct to within a couple of pounds. Public sector pension contributions are easy to input for me, perhaps yours not so easy?
You need to compare the figures from the salary calculator with a payslip and see where they differ.

It’s the tax where It differs. Could it be because I started this job in May?

Are you on the correct tax code?

Have you gone onto advanced options and added the correct tax code and your pension contributions as both will affect the amount of tax you pay

Yes I’ve added tax code, pensions and benefits

The taxable income, pension deduction etc all match on my payslip to the calculator. It’s literally the tax that’s very far off. Could it be that my employer’s pay system is calculating it wrong?  I am very concerned about getting a huge bill from HMRC at the end of the year.

Were you working before May ?
I can think of two possible scenarios that might explain you paying less tax than you think up to now...

a) You moved jobs and both your current and previous employers gave you Mays monthly tax allowance - this will have resulted in you underpaying tax.  
b) You weren''t in a job previously and so Aprils monthly tax allowance was effectively available to be spread over subsequent months by your current employer until you end up paying the correct amount of tax

We're not going to see the actual figures, and quite rightly so, so you need to speak to your payroll and ask them if there's any reason why the figures are so different. People on here can only really guess.

You don't want to give figures but give us your tax code at least
