As I wrote a short while ago, for a long time people have been emailing and requesting that The Salary Calculator offer support for pension contributions. My excuse had always been that pension contributions aren’t as simple as they might seem, but now I have finally tackled the problem.

Deductions made at source for a company pension or other pension scheme are typically a percentage of your salary, and any contributions you make to the pension are not taxed. The complication comes when employers calculate what is called “pensionable pay” – it is a percentage of this that is deducted each paycheck. As you can see in this related article about pensions, this is not necessarily just your annual salary – each employer calculates it differently.

Therefore, the pension deductions which have been added to The Salary Calculator are an estimate. They may match exactly what your employer does, but probably they will not. However, this is an improvement to the calculator in that it can give you a better indication of what your take home pay will be after pension contributions than it could before.

The approach I’ve taken is to take the percentage you enter into the pension field and deduct that percentage from the standard annual salary (i.e. not including any overtime). Therefore, the calculator is assuming that your pensionable pay is the same as your annual salary. If your employer calculates it differently I’m afraid that this estimate won’t be accurate, but it should give you a good indication. Sorry I couldn’t make it more accurate! Get started on The Salary Calculator with pension contributions.

22 Comments to Pension contributions on The Salary Calculator

  1. Found the calculator extremely useful.
    However, one of the things I’m trying to do is calculate how much AVC contribution I need to make to keep my taxable pay under the 40% threshold.
    It would be really useful if the calculator offered some sort of ‘flag’ to indicate whether the calculation included some tax in the 40% band. Then by increasing the pension % until the flag dropped I could find the answer easily.

    Many thanks.

  3. That’s an interesting thought, John, and I can see a couple of ways to go about it. In a post about new April 2010 tax rates I explained that early next year I’ll be updating the calculator. I will see if I could include some kind of indicator then.

  5. it would be great if the calculator could deal with salary sacrifice (http://www.hmrc.gov.uk/specialist/salary_sacrifice.htm) pensions, as this affects the amount of NI and I.T. paid

  7. Hi

    Your site is fantastic, but if you can help me with this question, i would be really grateful.

    Just got a job, i start in 5 weeks, the salary is 30k, and they will contribute 13% pension. I dont kbwo if that means i will have to contribute 13% also?

    If it is yes, that would decrease my salary by 3900, would the tax releif cover that?

  9. Hi Ali,

    In my experience, when a company says that they will contribute a certain percentage to a pension, it normally means that they will contribute the same percentage that you agree to contribute, up to a maximum (in this case 13%). In that case, if you chose to contribute only 6% (say), they would also contribute 6%. However, each company handles these things differently so the best thing to do would be to ask the HR or Payroll department to explain it to you.

    In my blog post above, I explained that amount contributed to the pension is sometimes not as simple as just a percentage of the gross salary (see above), but if it is then 13% would indeed be £3,900 per year. The tax relief would cover this, but it does mean that your take-home pay does not decrease by £3,900 per year. Use the Salary Calculator to see what difference it would actually make to you each month, although as before you would need to check with your employer to see exactly how they calculate the amount to deduct.

    I’m sorry I can’t be more helpful, but because not everyone’s employer handles pension contributions the same way, the Salary Calculator can only give you an indication of what the impact might be.

  11. Please could you tell me where the pension field is on the salary calculator?
    l have previously used this calculator with the
    pension field but it seems to have been removed.

  12. KJ on August 13th, 2010
  13. Hi KJ,

    The pension field is still there but is not in quite the same place. I have tried to tidy up the calculator and have put the pension and overtime fields into an “Advanced” section. Underneath the field where you enter the salary (or the hourly rates) there is now a link “Show advanced options…” – if you click on this you should see it expand to show you the pension field.

  14. admin on August 13th, 2010
  15. Yes, if you place the cursor on the top field of the advanced options and press “Tab” this will eventually take you down to the pension information fields.

  17. Hi,

    I was hoping for some advice after using this site.

    I have a tax code of 810L, Annual Salary of £21275 and a bonus of £77.73 (one off). My ‘take home’ on my pay slip is £1444.70 but this sites calculator advises it should £1469.57.

    Can anyone advise why there is a difference?

    I also contribute £42.55 monthly to a pension but I was under the impression this was tax free.

    Thanks,

  18. Michael on October 2nd, 2012
  19. Hi Michael,

    Does your payslip show the deductions for this month so you can compare with the deductions on the calculator and see where the difference lies? It might be that your employer considers bonuses to be “pensionable”, and therefore they’ve increased your pension contribution in line with your extra income this month. The calculator doesn’t do this, as not all employers do.

    I hope this helps!

  21. Hi,

    The only deductions my pay slip refers to are National Insurance, Tax & Pension.

    The extra money isn’t really a bonus but a payment for doing a sleepover in work.

    I’m not sure what you mean when you advise to compare the deductions on the calculator.

    Any further guidance would be appreciated.

  22. Michael Paton on October 7th, 2012
  23. Hi Michael,

    What I meant in my suggestion was to compare the values that are deducted for tax, NI and pension in your payslip with those that are shown by the calculator. This would help explain where the discrepancy lies. For example, I have just checked your figures in the calculator, and I can only get a take-home of £1469.57 by missing out the pension deduction. If I add your pension deduction (which appears to be 2.4%) to the “pension” section of the calculator, in a bonus month the Calculator thinks you should take home £1454.95, which is closer to what you have been paid.

    The remaining £10 might be because your employer has worked out your tax and NI as if you were getting this bonus every month, which would lead to you having to pay more tax over the year. This happened to me once, and my employer reduced my tax the following month to correct for it. If you are unsure, your manager or HR department should be able to explain the deductions to you.

  25. Thanks for your input – makes more sense now.

  26. Michael Paton on October 12th, 2012
  27. I have put my new tax code into the calculator and the discrepancy with my wage slip is exactly my pension contribution.
    The calculator adds the pension contribution to my tax allowance, effectively removing it from taxable pay whereas on my wage slip it is taken after the tax calculation based on my tax code has been done.
    My tax code includes an amount for tax relief on my pension and was under the impression that pension contributions are taxable, so I don’t know why on the calculator it is being treated as not taxable.

    Can you advise? Many thanks

  29. Hi Debbie,

    There are a couple of different types of pension, with different tax and National Insurance implications. The Salary Calculator at the moment only supports occupational pensions, where the payment is made before tax is deducted.

    It sounds like your employer might be making contributions for you into a personal pension scheme, where the contributions are taxed but you get some tax back from the government. Some information explaining the difference is available here: http://www.nidirect.gov.uk/tax-relief-on-pension-contributions

    If you are unsure, your employer’s HR or payroll department should be able to explain your deductions.

    There is another type of pension contribution known as a salary sacrifice pension – this has slightly different tax implications again. I do plan to add these different types of pension to the calculator but for the moment I’m afraid it is not able to work these out.

  30. admin on February 25th, 2013
  31. Yes, my employer is making contributions for me and I should receive tax back through my tax code.

    Thanks for clarifying this, I have found the site very useful.

  32. Debbie on February 25th, 2013
  33. I have found the salary calculator very useful and much more accurate than similar offerings on the web.

    With regard to overtime though it assumes a 37.50 basic week whereas we are lucky enough to only work 37.00! Would it be possible at some stage to have to input basic full time hours equivalent for a more accurate calculation?

    Best wishes

    Lena

  34. Lena Campbell on June 10th, 2013
  35. Hi Lena,

    Thanks for your feedback! I would like to add the option to input the number of “normal” weekly hours worked, as you suggested, but the problem I keep finding with this (and other ideas) is that it’s difficult to find space on the calculator without having to rearrange everything! I have recently been asked to make a couple of other improvements, though, which might mean I can re-jig everything to fit this option in too. In the meantime, you can do it using the hourly wage calculator. I know it’s a bit of a pain, but if you know your normal hourly wage (or work it out from your salary), you can enter it in here along with 37 hours per week, and the calculator will work out your overtime as you expect.

  36. admin on June 10th, 2013
  37. So exactly how many ways can pension contributions be calculated? Surely not that many so wouldn’t a calculator based on each method be an easy solution?
    Maybe I’m missing some magical equation or is it a way of keeping the whole thing mystical afterall its purely mathematical.

  38. Rob on October 18th, 2013
  39. Hi Rob,

    You might be surprised! The Salary Calculator currently supports 5 different pension calculations (Employer pensions and Salary Sacrifice pensions, each of which can either be contracted out or not, and personal pensions, which can’t). This covers the major types of pension calculations, but they all require “pensionable pay”.

    As explained in the article I linked to above (click here), employers can use almost any definition of “pensionable pay” they like, so giving options for all the different types isn’t possible. In the article, there is a (non-exhaustive) list containing 7 possible options – to include just these options would bring the total number of calculation types from 5 up to 640!

  41. Hi,
    I like your take home calculator and I am just after a bit of advice. My company takes my pension out after tax and then the tax is refunded back into my pension pot. I am moving into higher rate tax bracket but only 20% is refunded what will happen to the other 20%?

  42. Jake edwards on December 19th, 2013
  43. Hi Jake,

    Your employer, or whoever operates the pension scheme, should be able to tell you exactly what will happen when you are a higher rate tax payer, but probably you will have to claim back the extra tax paid from HMRC. You can do this either through your tax return or by simply contacting them. This page on the HMRC website explains how some companies manage their pensions like personal pensions, and the “Personal Pensions” heading provides a bit more detail.
