A simple calculation on the DIY investment platform shows if an investor would have started investing the full ISA allowance since it was introduced in 1999, into the average IA global fund at the beginning of each tax year the total contribution of £263,440 would have turned into £667,187. Investors who plan to put their money in towards an ISA can very week generate an extra £37,632 rather than making last-minute investment plans next year.
The investors effectively have nine years’ worth of growth: the portfolio would have matured to £629,555.

However, in the same period, if the investor would have invested the full ISA allowance in the average UK fund at the start of a given tax year, it would have generated £23,412 extra, i.e., £510,132 in place of £486,720.
For example- if an investor chooses to invest £20,000 at the start of each tax year for 10 years with a 5% return after charges, they will end up with a portfolio worth £264,136.

Best Cash ISA accounts
Investors who want to use their £20,000 ISA allowance as early as possible can now earn up to 0.92% with easy-access accounts, which is more than the average rate of 0.38% and far more than the 0.01% to 0.2% of interest offered by banks.
Cash ISA can be opened by a person aged 16 or over and works in a similar manner as a normal saving account but with tax-free interests. Taxpayers can earn £1,000 of saving interest a year without paying any tax on cash ISA, but if their earnings are over £150,000, they won’t get any tax allowance.
There are different types of cash ISAs, which include easy access, Fixed-rate, and others. With easy-access Cash ISAs, investors can withdraw money anytime, without any penalty. However, Fixed-rate Cash ISA offers a guaranteed rate but locks your contribution for a pre-decided period. In case, you want to withdraw money before the fixed lock-in period then you will have to pay some fee or penalty.
