Based on the payments you make, I think the bunq app could and should be able to calculate (extrapolate) the date at which you will probably reach your goal. For instance, I am saving up for a new iPhone. I would want to know when I will reach this goal, and based on the growth of my savings goal that I made for this, the date I will reach the goal can be calculated. It can look like this:
What's the difference with the prediction graph?
I can see that you can argue that the prediction graph is basically the same as what I'm looking for, yet I think it's not the same. The graph doesn't go so far and if you're spendings are seen over the course of a couple months, you can still get a pretty accurate estimation, even if the date is a little further away from today's date.
I think this feature could add a little more insight into when the goal will be reached, so that we can also anticipate on this. Let me know what you think about this!
