What Is Zero-Based Budgeting?

Zero-based budgeting is an accounting methodology where your total monthly income minus all allocated outflows (needs, lifestyle wants, debt servicing, and savings) equals exactly zero.

Income − (Needs + Wants + Savings + Debt Repayments) = ₹0

Having a "zero" balance does not mean you spend your bank account down to zero; it means every rupee has an assigned purpose before the month begins.

Frequently Asked Questions About Budgeting

What if I have an irregular or freelance income?

Use your lowest monthly income from the past 12 months as your baseline budget. Any surplus earned during peak months should be transferred to a holding buffer account rather than inflated lifestyle spending. Read our guide on Managing Irregular Income.

How is this different from the 50/30/20 rule?
