The 50/30/20 rule

A simple budgeting framework: spend roughly 50% on needs (rent, groceries, utilities, transport), 30% on wants (eating out, subscriptions, entertainment), and put 20% toward savings and debt repayment. The calculator shows your current split and where you can adjust.

How to use it

  2. Add your fixed and variable expenses by category.
  3. Review your remaining cash flow and savings rate.
  4. Open a Savings Pod in Squirrelll.ing to automate the savings portion daily or weekly.
