Hi @PhilA - welcome to the community
Thanks for this insight. This is actually the correct behaviour for that particular ‘card’.
The goal of these home-page cards is to highlight specific activity rather than just your balances. You can already get your balance in a number of ways, including on the Dozens home (you can click the down chevron below your balance to see the balance in your cash savings and your investments for example).
The yellow ‘Grow’ card shows the amount that has been ADDED to your cash savings whether manually, automatically (via rules) or through any bond interest payments.
We want to celebrate the fact that you managed to put money aside whatever you then decided to do with this amount. This figure is important since it includes all the small amounts from IFTTT rules or roundups that accumulate over time and you might otherwise not realise are having a cumulative effect.
Of course, you may have then used some of this amount you’ve put aside, either as a withdrawal, or maybe by buying an investment, and this will be reflected in your balance, but not on this ‘card’.
In your case, you put £100 into your cash savings and this will not change this month unless you add more, but your balance is £95. If you click on ‘Grow’ you will see that reflected at the top of the page as well as in the graph.
Does this make sense?
