Showing only the value of the percentage calculation

I want to be able to show only value of a % calculation in a table, how can i do this?

For example if I have a £1000 and add 3% the formula =a2*1.03 will show the total of £1030, i just want it to show the working of the increase in the % but only show the £30.00 not the total as i want to be able to add it to a total later on in the table.

Anyone know how to add the formula or if it can be done?

Thanks
