The 50/30/20 rule: a simple budgeting formula

The 50/30/20 rule helps distribute income quickly and keep balance between obligations, lifestyle, and future savings.

What 50/30/20 means

• 50% of income: mandatory expenses
• 30%: wants and lifestyle spending
• 20%: savings and investments

Typical categories in each bucket

50% mandatory

• rent or mortgage
• utilities
• basic groceries
• commute costs
• required debt payments

30% wants

• cafes and restaurants
• entertainment
• hobbies
• travel
• non-essential purchases

20% future

• emergency fund
• long-term savings
• investments
• early payoff of expensive debt

Example calculation

If income is 120,000 RUB:

• 60,000 RUB mandatory
• 36,000 RUB wants
• 24,000 RUB savings

When to adapt the formula

If mandatory expenses exceed 50%, first focus on:

• reducing fixed costs
• increasing income
• restructuring expensive debt

A temporary 60/20/20 split can be reasonable.

How to implement in practice

1. analyze 1-2 months of real spending
2. map categories to the three groups
3. set monthly limits
4. check deviations weekly

Conclusion

50/30/20 is an effective starting framework. It is simple, clear, and helps restore order in personal finances quickly.
