Capital withdrawal planning tool

This financial planning tool calculates the capital gain on a given withdrawal from an investment, and the amount of withdrawal which can be made when utilising an individual or trustee’s CGT exemption.

The tool provides a guide to any gain or loss created by a withdrawal based on the information input by you. It does not assume any additional allowable deductions which may be available to your client, such as cost of disposal. The tool does not take into account any ‘income’ and assumes the capital value input reflects any increase in value of reinvested income, for example via income or accumulation units. The tool does not consider any ‘matching’ rules.

Capital withdrawal planning tool

Where a portfolio consists of, for example, five funds, each calculation needs to be made at individual fund level.


£100,000 invested 


£20,000 in each fund – A/B/C/D/E

The figure £20,000 should be inserted in the investment capital amount, and the value of that investment in the fund value before withdrawal.

Five separate calculations would need to be made in this example.

Calculate gain option

This will calculate the gain based on a capital withdrawal from the investment and takes no account of any income received.

The amount of invested capital will need to be reduced every time a withdrawal is made:

eg year one

£100,000 amount of invested capital 


£10,000 withdrawal made, of which £7,000 is capital, £3,000 is gain.

The figure for the next calculation (year two) would be £93,000 for the amount of invested capital. The invested capital amount is reduced by the capital element from year one withdrawal (£7,000), not the total withdrawal amount (£10,000). Where an investment has had previous withdrawals you will need to input the correct, recalculated figure for the remaining invested capital, to ensure the calculation is correct.

Calculate withdrawal option

This will calculate the maximum amount of capital which can be withdrawn from an investment to maximise use of an individual’s or trustee’s available CGT exemption.

How to use the tool
