The cheapest Airtel data plan: cost per GB by validity
The cheapest Airtel plan depends on what you mean. The plan with the lowest price is not the one with the lowest cost per GB, and a plan that is cheaper per GB only saves money if you use all of it before it expires. Prices below are from Airtel’s own website, read on 11 November 2026.
Cost per GB by validity
Cost per GB is the price divided by the main data allowance. We list plans of 1 GB or more and leave out social-app plans.
| Validity | Cheapest per GB | Price | Cost per GB | Most expensive per GB |
|---|---|---|---|---|
| Daily | 1GB Binge | ₦500 | ₦500 | only plan |
| 2-day | 3GB Binge | ₦750 | ₦250 | 2GB Binge (₦600, ₦300 per GB) |
| Weekly (7 days) | 20GB | ₦5,000 | ₦250 | 1GB (₦800, ₦800 per GB) |
| Monthly (30 days) | 160GB | ₦30,000 | ₦188 | 2GB (₦1,500, ₦750 per GB) |
| 90 days or longer | 685GB (365 days) | ₦100,000 | ₦146 | 350GB (₦60,000, ₦171 per GB) |
The monthly 40GB Everyday-ON plan (₦7,500) comes to ₦188 per GB, released in daily portions.
Match the plan to your use
- Light use, a few GB a month: the 4GB monthly plan is ₦2,500 (₦625 per GB). Small plans cost the most per GB.
- Medium use, 20 to 35 GB: the 25GB plan is ₦8,000 (₦320 per GB) and the 35GB plan ₦10,000 (₦286 per GB).
- Heavy use, 100GB or more: the 100GB plan is ₦20,000 (₦200 per GB) and the 160GB plan ₦30,000 (₦188 per GB).
Weekly or monthly?
Four weekly 20GB plans cost ₦20,000 for 80GB, against ₦20,000 for the 100GB monthly plan. For regular use the monthly plan is the better buy; weekly plans suit you when you do not need data for a whole month.
Watch for these traps
- Cheap per GB, but too big: unused data expires.
- Always buying daily plans: they cost more per GB than a bigger plan.
- Bonus data: the YouTube and social allowances help only if you use them, and we do not count them in cost per GB.
- Old prices: confirm with Airtel (dial *312#) before you pay.
