Understanding the 50/30/20 rule
50% needs
Half of income for essentials: food, housing, transport, bills, mandatory installments. If this exceeds 50%, look for ways to reduce it.
30% wants
For lifestyle: entertainment, eating out, subscriptions, hobbies. This is the most flexible part to adjust when you need to save more.
20% savings & investment
For emergency fund, investing, and paying debt above the minimum. This part builds your future wealth.

What if my needs exceed 50%?
Common in big cities. You can temporarily lower the wants share, find reducible living costs, or increase income. The key is to keep a savings share.
Is the 50/30/20 ratio mandatory?

Do installments count as needs or wants?
Mandatory installments (mortgage, vehicle loan) generally count as needs. Installments on lifestyle items (paylater for wants) fit the wants category. Classify per your context.
