Estimate how new purchases would affect the future months

[eryc-cc]

The Problem

One of the issues I have is not having clarity over the “total amount” I’ll be paying the following months.

• How do I decide if a purchase is feasible for the time being?
• How do I know whether I’m going over budget?

The Solution

A page where you add the purchase to simulate what the following months will look like.

It won’t add up to the transactions list. It just temporarily calculates it for you.

• Needs a specific page for that.
• Ability to preview “monthly installments”
• Overview for the current month (can have the details)
• Overview of the following months (just a total)
• Ability to add to a specific transaction (sum the current amount and add the amount)

Depends on:

• Improve the rendering from localStorage: currently re-renders everything on the page #5
• Refactor JS Code - Possibly close Issue #5 #7
• [Overview Data] Calculate the overview data #9
• [Overview Component] Render the overview data #10
