The government agrees that the average Gross salary in UK is approx £37,500.
The government promises to pay out 80% of an employee's salary up to the average salary limit.
80% of £37,500 is £30,000.
This payout (called Furlough) equates to a gross salary £30,000 per year, or £2,500 per month.
This is gross salary before tax deductions.
The max take home pay (what goes into you bank account, Net) is likely to be closer to £1,994 per month. (Check out www.listentotaxman.com and use £30,000 as your new salary)
Someone who earns less than £37,500 will see their monthly take home pay reduced by 80%.
Someone who earns more than £37,500 will take home the maximum promised which is £1,994; and consequently see their pay reduced by alot more than 80%.
For example: someone earning £45,000 gross salary should normally receive £2,625 (net monthly) per month after typically taxes. However if this person is furloughed then they would automatically drop to £1,994 per month and thus see a 25% reduction in monthly take home pay.
