50/30/20 Rule Calculator


simplify your spending

The online 50-30-20 calculator divides your monthly income into necessities, wants and savings. A classic rule of thumb is to split your monthly salary as follows:  

  • 50% goes into necessities (essential expenses such as rent and bills) 
  • 30% goes towards wants (such as food, activities, subscriptions and petrol) 
  • 20% goes towards savings or debt repayments 

Of course, the amount you’ll be able to put into these pots will differ based on your circumstances. If your spending doesn’t fit the rule, that’s okay – but it gives you a good goal to aim for.
