Compare different recharge durations on the same basis. Enter the upfront price and the actual validity in days. The calculation runs in your browser; it does not ask for a mobile number or send your entries to our server.
How the calculation works
Daily cost = recharge price ÷ validity in days. The 30-day equivalent multiplies that daily result by 30. Results are rounded to two decimal places for display; the calculation uses the unrounded daily value.
For an illustrative ₹280 recharge lasting 28 days, the daily equivalent is ₹10 and the 30-day equivalent is ₹300. These are comparison figures. They do not imply that an operator sells a ₹300 monthly version of the same pack.
What to enter
Use the price for the pack and its actual fixed-day validity. Do not enter 30 simply because an article calls a 28-day pack monthly. For a calendar-month product, check the applicable period and terms; this tool does not model calendar renewal dates.
The tool accepts positive prices up to ₹100,000 and whole-day validity from 1 to 1,095 days. Those are input boundaries for the calculator, not claims about available recharge products. Zero-day validity cannot produce a meaningful daily cost.
A worked comparison
Imagine Pack A costs ₹240 for 24 days and Pack B costs ₹300 for 30 days. Both calculate to ₹10 per day. Their upfront payments differ, but their normalized daily price is equal. The data, calling and coverage could still be different.
If you buy add-ons regularly, repeat the calculation with the base cost plus the add-on spending for the same period. Label that as your effective spending estimate rather than the operator's listed pack price.
What the result does not decide
The calculator does not evaluate coverage, network speed, unused data, 5G eligibility, promotional benefits or refund terms. It does not predict future prices or recharge your connection. A lower daily figure is useful only if the service and allowance meet your needs.
Use the plan finder to examine selected options, then read how to choose a prepaid plan before making a purchase on the operator's official site or app.
