The 50/30/20 Budget in Action: A Month in the Life of a ₹40,000 Salary

Efficient budgeting for expenses and savings.

We all love theories. “Spend less than you earn,” “Save 20%,” “Budget your money.” Sounds great. But what does it look like in real life for a typical Indian family earning ₹40,000 in a metro?

Meet Rahul and Priya (names changed), a couple in Bangalore with a 4-year-old daughter. Rahul earns ₹40,000/month. Priya manages the home. This isn’t a theoretical exercise—this is their actual budget that helped them save, invest, and still live with dignity.

If you’ve ever thought “budgets don’t work in real India,” this post will change your mind.

Part 1: The Raw Numbers – Where ₹40,000 Actually Goes

Monthly Take-Home: ₹36,200

(After PF, TDS—as we learned in our salary slip post!)

Using the 50/30/20 Rule:

  • Needs (50%): ₹18,100
  • Wants (30%): ₹10,860
  • Future (20%): ₹7,240

Part 2: The “Needs” Bucket (₹18,100) – Non-Negotiables

ExpenseAmount (₹)Notes
Rent9,0001BHK in outskirts, 30km from office
Groceries5,000Monthly ration, vegetables, milk
Daughter’s School2,000CBSE school fees (monthly average)
Electricity/Water800With careful usage
Cooking Gas500One cylinder lasts 2+ months
Internet/Mobile800Basic plan for work + family
Total₹18,100Exactly 50%

Reality Check: Notice—no car EMI, no eating out in “Needs.” Rent is kept at 25% of take-home (ideal). School fees hurt but are non-negotiable.


Part 3: The “Wants” Bucket (₹10,860) – Life’s Joys

ExpenseAmount (₹)Philosophy
Eating Out1,500Twice a month at decent places
Entertainment1,000OTT subscriptions + occasional movies
Shopping2,000Clothes, household items (staggered)
Petrol2,360Office commute (30km daily on bike)
Weekend Outings1,000Park, mall visits with daughter
Gifts/Donations1,000Birthdays, festivals, temple
Miscellaneous2,000Medical, repairs, unexpected
Total₹10,860Used consciously

Key Insight: They use the envelope system—₹10,860 cash withdrawn on 1st. When it’s gone, wants spending stops. No exceptions.


Part 4: The “Future” Bucket (₹7,240) – Building Tomorrow

InvestmentAmount (₹)Purpose
Emergency Fund SIP3,000Liquid fund (building to ₹2 lakhs)
Daughter’s Education2,000Equity fund (18-year goal)
Retirement (NPS)1,000Extra beyond PF
Term Insurance540₹1 crore cover (age 30)
Health Insurance700Top-up over company insurance
Total₹7,240Automated on 1st

The Automation Magic:
All these are auto-debited on 2nd of month. Rahul never sees this money in his account. “Out of sight, out of mind, into future.”


Part 5: The Real-Life Challenges & Solutions

Challenge 1: “Unexpected Expenses Every Month!”

Solution: The ₹2,000 “Miscellaneous” in Wants covers 90% of surprises. For bigger ones, emergency fund (once built).

Challenge 2: “Festivals Destroy Our Budget!”

Solution: They save ₹500/month in a “Festival Fund” separate savings account. Diwali/Christmas comes from here, not regular budget.

Challenge 3: “Medical Emergencies?”

Solution: Company insurance (₹3 lakh) + top-up (₹10 lakh) + emergency fund building.

Challenge 4: “We Want a Vacation!”

Solution: ₹1,000/month in “Vacation Fund.” Every 2 years, they take a ₹24,000 trip.


Part 6: Their Monthly Money Ritual (You Can Copy)

Last Sunday of Every Month:

  1. Review: Check last month’s spending (using expense tracking app)
  2. Plan: Allocate next month’s buckets
  3. Withdraw: ₹10,860 cash for “Wants” envelope
  4. Automate: Ensure all SIPs/transfers are scheduled
  5. Celebrate: Small treat if they stayed on budget

Every 6 Months:

  1. Check insurance renewals
  2. Review investments
  3. Adjust for inflation (increase SIPs if salary increased)

Part 7: The 3-Year Transformation

This budget didn’t happen overnight. Three years ago:

  • They had no emergency fund
  • Lived paycheck to paycheck
  • Had credit card debt
  • No investments beyond PF

Today:

  • Emergency fund: ₹1.2 lakhs (60% to target)
  • Daughter’s education fund: ₹72,000 growing
  • Zero debt except home loan planning
  • Peace of mind: Priceless

  • Permission to save for dreams without anxiety
  • Permission to live today while building tomorrow
