CJRS & BrightPay - where pay periods cross 2 calendar months


The Furlough Pay Calculator


Where a pay period straddles two calendar months, BrightPay’s furlough pay calculator will automatically apportion using a daily basis approach.


An employee’s weekly pay period runs from 30th January 2021 – 5th February 2021. Their regular wage is £500 and they are being fully furloughed.

Therefore 2 days of the pay period fall in January and 5 days in February.

1. Work out the daily pay rate = £500/ 7 days = £71.43

2. Perform the January calculation = £71.43 x 2 days = £142.86 x 80% = £114.28

3. Perform the February calculation = £71.43 x 5 days = £357.15 x 80% = £285.72

4. Total up the 2 amounts = £114.28 + £285.72 = £400.00*

* In some instances, users may see a few pence difference if comparing HMRC's calculations or a manual calculation with those calculated in BrightPay. This is because the published HMRC calculations are based on rounded amounts for making manual calculation easier. BrightPay uses a more direct and accurate algorithmic version of the calculation instead.




The Claim Report


Where a pay period straddles two calendar months (and thus 2 claims are required), BrightPay will apportion the pay period's gross pay into each claim period on a daily basis. Each day then has a relative weighting in line with the maximum reclaimable daily wage amounts as stipulated by HMRC. This is the only method that guarantees accuracy in all scenarios.


  • Claim period is 30th January – 31st January

  • Weekly pay period falling in claim period = 30th January – 5th February

  • Employee is paid a reclaimable furlough pay amount of £400.00 in the pay period

  • Therefore, there are 2 days in this claim period that will be accounted for.

In this instance, the pay period straddles the claim period, so we have to work out the percentage apportionment.

This is done using the ‘maximum reclaimable wage’ amounts for January (£2,500) and February (£2,500) as follows:








Likewise, the calculation being performed and the amount included in the February claim will be:
