## Formula

Validity in days = days, or months × 365 ÷ 12. Cost per day = price ÷ validity days. Cost per N days = cost per day × N. Recharges per year = 365 ÷ validity days. Cost per GB = price ÷ total data (per-day data × validity days).

- A 28-day pack needs about 13 recharges a year, not 12, so compare plans per day rather than per pack.
- Calendar-month packs are averaged at 365 ÷ 12 ≈ 30.42 days; actual months are 28–31 days.
- Validity in days = days, or months × 365 ÷ 12. Cost per day = price ÷ validity days. Cost per N days = cost per day × N. Recharges per year = 365 ÷ validity days. Cost per GB = price ÷ total data (per-day data × validity days).
- Inputs used: Plan A: price, Plan A: validity, Plan A: validity unit, Plan A: data allowance (optional), Plan A: data is, Plan B: price, Plan B: validity, Plan B: validity unit, and other shown inputs.

- Plan B: validity unit
- Plan B: data allowance (optional)
- Plan B: data is
- Plan C: price

- Plan C: data allowance (optional)
- Plan C: data is
- Also show cost for (optional)
- Currency (symbol only, never converted)

## Worked example: 200 for 28 days (30 GB) vs 249 for 1 month (30 GB) vs 299 for 30 days (1.5 GB/day)

Per day: 7.14, 8.19 and 9.97 — Plan A is cheapest per day; Plan C is cheapest per GB (6.64).
1. Plan A: 200 ÷ 28 ≈ 7.14 per day; × 365 ≈ 2,607.14 a year.
2. Plan B: 1 month = 30.42 days; 249 ÷ 30.42 ≈ 8.19 per day.
3. Plan C: 299 ÷ 30 ≈ 9.97 per day; data 1.5 × 30 = 45 GB → 6.64 per GB.

## Common questions

### Why is a 28-day pack more expensive than it looks?

A year has 365 days, so 28-day validity means about 13.04 recharges a year instead of 12. Comparing cost per day shows the real difference.

### Does it include operator prices for my country?

No. Plans change often and differ by operator and region, so you enter the price and validity shown by your operator. Any currency works and nothing is converted.

### Which is better: cheapest per day or cheapest per GB?

Cheapest per day matters if you use little data; cheapest per GB matters if you use most of your allowance. The calculator shows both.

### How are calendar-month packs handled?

They are averaged at 365 ÷ 12 ≈ 30.42 days so they can be compared with day-based packs.

### How do I calculate a mobile recharge plan's cost per day?

Divide the pack price by its validity in days. For example 200 for 28 days = 7.14 a day; multiply by 30 for a monthly figure or by 365 for a yearly one.

### How do I use the Mobile Recharge Plan Comparison Calculator?

Enter the required values for Plan A: price, Plan A: validity, Plan A: validity unit, Plan A: data allowance (optional), Plan A: data is, and the other fields shown. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

## Limitations and assumptions

- Compares price, validity and data only; calls, SMS, speed after the data cap and bundled apps are not valued.
- Prices are entered by you; offers, taxes and renewal price changes are not included.
- Assumes you renew the same plan back to back for the yearly figures.
- An estimate built only from the figures you enter. It is not financial, tax, legal or employment advice, and real costs, taxes and returns vary.
- The result depends on the values you enter for this mobile recharge plan comparison calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
