No matter how disciplined we are with our personal finances, it can sometimes feel like a challenge to consistently budget and save money.

Human willpower is a finite resource. So, while a money-saving app or budgeting app like Plum can help automate aspects of your financial strategy, it’s important to allow yourself a little leeway in your budget for the odd treat, too. And this is where our new Naughty Rule might come in handy!

What is the Plum Naughty Rule?

Plum’s AI is designed to analyse your spending and adapt.

We also offer Round Ups and gamified Rules, like the 52 Week Challenge and Rainy Days, to make the process of setting money aside more engaging. Because we believe they can help you save more over the long term.

The Naughty Rule is the latest addition to our range of automated deposit methods. It will set money aside whenever you shop with a merchant that you specify as ‘Naughty’ 🤭 Not that we would ever judge!

We made this Rule to recognise the fact that we all need a cheat day away from our budget occasionally. It can ease some of the associated ‘buyer’s remorse’ from your naughty purchase… And most importantly, keep you moving towards your goals when you feel you deserve a treat.

How does the Naughty Rule work?

Customers can use the Plum app to choose from a selection of retailers where they might want to limit their spending, such as fast food outlets and clothing stores. So, whether your weakness is takeaways or online shopping, we’ve got you covered.

Once the customer has confirmed their particular Naughty merchant, we’ll arrange to deposit a fixed amount of money whenever they spend with them using their linked bank account or Plum Card.

The amount that’s set aside is controlled by the customer through the Plum app, with options ranging from £1 (for those feeling ‘Mildly Mischievous’) to £10 (for those feeling ‘Very Villainous’).

The Rule can only be triggered a maximum of once per day, should the customer make multiple purchases from the retailer within a 24-hour period. Money is taken weekly, in a combined deposit with other Rules.

Who can use the Naughty Rule?

The Naughty Rule is currently available to UK customers who are subscribed to our Plum Ultra tier (priced at £4.99 per month, with a trial month free).

It forms part of our Ultra suite of smart budgeting tools, which also includes:

  • Our Visa debit card lets you spend money straight from Plum.
  • Money Maximiser can help earn interest and manage your budget.
  • Enhanced Cashback on purchases (+33% vs. Pro tier).
  • Access to the 1p Challenge (to set aside £667.95 in a year).

Note, for customers who want to access all of Plum’s features (including our full range of investments and automation options), we offer a Premium tier.

Save as you spend by setting aside any spare change from purchases.

Pay Days
