📘 About the 50/30/20 Budget Calculator
The 50/30/20 rule is the simplest way to budget: spend 50% of your take-home pay on needs, 30% on wants and put 20% into savings and extra debt repayment. You set three limits instead of tracking every rupee.
Enter your monthly in-hand salary to see the exact amount for each bucket, the yearly split, an emergency-fund target and how much your 20% could grow to if invested every month.
The rule was popularised by US senator Elizabeth Warren in the book 'All Your Worth', and works for any currency.

❓ Frequently asked questions
What is the 50/30/20 rule?
A budgeting rule that splits take-home income into 50% for needs, 30% for wants and 20% for savings and debt repayment.
How do I calculate a 50/30/20 budget?
Multiply your monthly take-home pay by 0.5 for needs, 0.3 for wants and 0.2 for savings. On ₹60,000 that is ₹30,000, ₹18,000 and ₹12,000.
Should I use gross or take-home income?
Take-home (in-hand) income, after income tax and PF deductions.
What if my rent is more than 50% of my income?
Cut wants first, look for cheaper housing or flatmates, and try to keep savings at 20%. A 60/20/20 split is a common fallback.
Is the 50/30/20 rule right for everyone?
It is a starting point. High earners can save more than 20%; people in costly cities may need 60/30/10 for a while.
Is it 50/30/20 or 50/20/30?
Both names describe the same rule: 50% needs, 30% wants, 20% savings.
