2023: Week 50 - Regular Savings Accounts Part 2

Challenge by: Jenny Martin

Data Source Bank (DSB) were so thrilled with the workflow produced for last week's challenge. As often happens with great analysis, further questions were raised. 

Which would be the best account for a customer given the amount they're able to deposit each month?

 Of course, it made sense for the previous challenge that the accounts that allowed higher monthly deposits ranked highly, but what if a customer only has a fraction of that monthly deposit, which account would best suit them then? 

Input

We'll be tweaking the workflow that was built last week, which can be found here - or of course you can use your own workflow from last week!

Requirements

  • Introduce a field which allows a used to control their Planned Monthly Deposit
  • If this value is greater than the Max Monthly Deposit allowed by the Provider, then calculate how much will be left over and receive no interest
    • Although you'll want to make sure these leftovers are added on after the interest has been applied
  • Output the data
    • Make it clear what the Customer's Planned Monthly Deposit is in the title of the output file

Output

Example output using £300 as the customer's planned monthly deposit:

  • 12 fields
    • Providers Ranked by Max Savings
    • Providers Ranked by Total Interest
    • Provider
    • Interest
    • Max Monthly Deposit
    • Customer Planned Deposit
    • Monthly Deposit
    • Leftover Savings which won't receive interest
    • Month
    • Savings each month
    • Max Possible Savings
    • Total Interest
  • 144 Rows (145 including headers)
You can download the output from here.

How to...Handle Free Text

Image
Free isn't always a good thing. In data, Free text is the example to state when proving that statements correct. However, lots of benefit can be gained from understanding data that has been entered in Free Text fields. What do we mean by Free Text? Free Text is the string based data that comes from allowing people to type answers in to systems and forms. The resulting data is normally stored within one column, with one answer per cell. As Free Text means the answer could be anything, this is what you get - absolutely anything. From expletives to slang, the words you will find in the data may be a challenge to interpret but the text is the closest way to collect the voice of your customer / employee. The Free Text field is likely to contain long, rambling sentences that can simply be analysed. If you count these fields, you are likely to have one of each entry each. Therefore, simply counting the entries will not provide anything meaningful to your analysis. The value is in
