Assumed: typical shares of take-home pay for food, bills, travel and saving, metro city costs. Change

The other lines are worked out from typical households. Open “Change what I spend on each line” under the result to put in your own amount for any line.

Add your statements in the Expense Tracker first to build the budget from what you really spent.

What if I spend less on one line?

You would save ₹2,000 a month, which is ₹24,000 a year. Left each month would be ₹4,400.

Your budget numbers are remembered only in this browser, on this device. Nothing is sent anywhere.

How to use this budget

  1. Put in your monthly take-home pay, your city type, your rent or EMI and the family size.
  2. Read the big number. It is what is left after the planned spending, each month.
  3. Open “Change” under the result to put in your own amount for any line.
  4. Try “What if” to see what a cut on one line saves in a month and in a year.

For example, with a take-home pay of ₹60,000 in a metro and rent of ₹15,000, about ₹57,600 goes out each month and ₹2,400 is left, which is ₹28,800 a year.

Why a budget is not enough on its own

A budget is what you plan to spend. It does not tell you what you really spent. Small UPI payments, card bills and festival months often make the real number higher than the plan.

To see what you really spent, add your bank and PhonePe statements in the Expense Tracker. Then use its numbers here with one tap, and compare your plan with the real spending, line by line.

Frequently asked questions

What is a household budget?

A household budget is a plan for one month: how much comes in, how much you plan to spend on each thing, and how much is left. The number to look at is the money left over. If it is below zero, more goes out than comes in.

What is the 50/30/20 rule, and why is it different for a metro?

A common guide says about 50% of take-home pay for needs (rent, food, bills, EMIs), 30% for wants and 20% for savings. In a big city rent takes a bigger share, so this page uses 60 / 20 / 20 for a metro. These are common guides, not advice. Your own life may need a different split.

How are yearly bills like insurance and school fees handled?

Spread them over 12 months. For example, an insurance premium of ₹24,000 a year is ₹2,000 a month. Put that monthly amount on the line, so the bill does not surprise you in the month it falls due.

Is my data uploaded?

No. All the working is done inside your own browser. The numbers you type are remembered only on this device, so the page opens as you left it. Use “Clear everything on this device” on the page to remove them. Nothing is sent to us or to any other server.

What is the difference from the Expense Tracker?

The Household Budget is a plan: what you expect to spend. The Expense Tracker reads your bank and PhonePe statements and shows what you really spent. Use the tracker first if you can, then bring its averages here with one tap, and compare your plan with the real spending.

Where do the starting amounts for each line come from?

They are typical shares of take-home pay for a household like yours, shown under “Assumed” on the page. They are rough guesses, not measured figures. Change any line to your own amount.

Is this financial advice?

No. It is a simple planning aid. The guides are common rules of thumb, and your own needs may be different.
