Budget Planner
Overview
What does Budget Planner do?
Type your monthly income and the tool returns three amounts: what to budget for needs (50%), for wants (30%), and for savings (20%). It is a simple, widely-used starting point for a monthly budget.
Adjust the percentages in your own plan if your situation calls for a different split.
Under the hood
How does it work?
The tool reads your income and multiplies it by 0.5, 0.3, and 0.2, rounding to whole rupees. The results are labeled Needs, Wants, and Savings.

Frequently asked questions
Common questions about Budget Planner
What counts as needs vs wants?
Needs are essentials — rent, groceries, utilities, transport. Wants are the rest — dining, entertainment, subscriptions.
Is 50/30/20 right for everyone?
It is a good starting point. If your rent is high or you carry debt, adjust — some plans shift more into needs or savings.
What if my income varies?
Use your average monthly income, or budget from your lowest month so the plan holds in lean months.
Is my data private?
Yes. Everything runs in your browser and nothing is transmitted or stored.
Should savings include debt repayment?
Many planners treat paying down high-interest debt as savings — the 20% bucket is a reasonable home for it.
