How this calculator works
It takes your monthly take-home pay, subtracts rent and EMIs (money that's already spoken for), then sets your savings goal aside. What remains is your spending money for the month, divided by the days in it. That gives a daily figure, which is easier to live by than a monthly one.
How much of your salary should you save?
A common starting point is 20% of take-home pay, the savings share of the 50-30-20 rule. If that isn't possible yet, start with 10%, or even a fixed ₹2,000, and move it out on payday. Raise it with each increment. A savings amount you keep every month beats a bigger one you abandon in March.
| Take-home a month | Save 10% | Save 20% | 20% over a year |
|---|---|---|---|
| ₹25,000 | ₹2,500 | ₹5,000 | ₹60,000 |
| ₹40,000 | ₹4,000 | ₹8,000 | ₹96,000 |
| ₹60,000 | ₹6,000 | ₹12,000 | ₹1,44,000 |
| ₹1,00,000 | ₹10,000 | ₹20,000 | ₹2,40,000 |
What to put in each box
- Take-home pay: what reaches your bank each month after tax and PF. Not your CTC.
- Rent: your share, if you split a flat.
- EMIs: home, car, phone, education or any other loan, added together. Credit card bills are spending, not EMIs, unless you've converted them.
- Savings goal: SIPs, recurring deposits, PPF and whatever else you want to put aside each month.
Everything else, groceries, bills, travel, food and fun, comes out of the daily number. That's the point: one figure for all the spending you control.

Questions people ask
How much should I save from my salary every month?
20% of take-home pay is a common target. If that's too much right now, start with 10% or a fixed amount, move it out on payday, and raise it with each increment.
How do I calculate how much I can spend per day?
Take-home pay minus rent, EMIs and your savings goal, divided by the days in the month. With ₹50,000 take-home, ₹15,000 rent, ₹5,000 of EMIs and ₹10,000 saved, you have ₹20,000 to spend, or about ₹666 a day in a 30-day month.
Should I count my credit card bill?
Not as a fixed cost. A credit card bill is spending you've already done, so track the card payments themselves as they happen. Count it as an EMI only if you've converted it into one.
Is my data saved?
No. The calculator runs in your browser and nothing you type is sent or stored.
