Roughly 8.5% interest? Where can I get some of that?
Assuming you just took 40% tax?
That was just a rough estimate. You only take off 40% tax after you've reached £40k.
6.5% of 1,000,000 is £65k.
£5,434 of that is not taxed, (more if your allowance is higher).
£2,230 is taxed at 10% so £223
£32,370 is taxed at 20% so £6,474
£24,966 is taxed at 40% so £9,986.4
Leaving £48,316.6 or £132.37 a day. And you can be happy that you are avoiding loads of tax that you would have to pay if you were earning this money, like national insurance.
8.5% interest would be £165.25 a day.
