50-30-20 Budget Rule Calculator
50% needs, 30% wants, 20% savings. But does your salary actually fit this rule? Let's find out.
Calculate My BudgetWhat Is the 50-30-20 Rule?
The 50-30-20 rule suggests allocating your after-tax income: 50% to needs (rent, food, transport, insurance), 30% to wants (eating out, entertainment, shopping), and 20% to savings (emergency fund, investments, debt repayment).
Popularized by Senator Elizabeth Warren, it's a starting framework — but most people in high-cost cities find the "50% needs" threshold impossible when rent alone takes 30-40%.
The 50-30-20 Rule Doesn't Work for Everyone
If you earn ₹40,000 in Mumbai, 50% (₹20,000) barely covers rent + food. Your "needs" might consume 65-70%, leaving only 10-15% for wants and 15-20% for savings. And that's okay.
The tool adjusts the 50-30-20 split to your actual situation. Instead of forcing a ratio, it calculates your real daily budget — which is far more actionable than knowing you're "10% over on needs."
From Percentages to a Daily Number
The real power of this calculator is converting abstract percentages into a concrete daily limit. If your 30% "wants" allocation is ₹15,000/month, that's ₹500/day for lifestyle spending.
Every time you're about to order food or buy something online, the question isn't "am I within 30%?" — it's "have I spent more than ₹500 today?" That's a question you can answer in 2 seconds.
