Office 2021 vs Microsoft 365 in India — Which to Buy? (2026 Price Comparison)
Buy Office 2021 (a one-time “lifetime” license) if you just want Word, Excel, PowerPoint and Outlook on your PC forever; buy Microsoft 365 if you want the latest features, cloud storage and multi-device use each year. At OTT24x7, a lifetime Office 2021 key starts at ₹150 and a Microsoft 365 year at ₹151 — so the deciding factor is features, not price. Here’s the full comparison.
Office 2021 vs Microsoft 365 — India price comparison
| Product | Type | Price (India) |
|---|---|---|
| Office 2021 Pro Plus — 1 PC (Phone) | One-time · lifetime | ₹150 |
| Office 2021 Pro Plus — 5 PC (Retail) | One-time · lifetime | ₹1,683 |
| Office 2024 Pro Plus LTSC — 1 PC | One-time · lifetime | ₹188 |
| Microsoft 365 — 5 devices, 1 year | Subscription · yearly | ₹151 |
What’s the actual difference?
- Office 2021 (one-time) — you pay once and own that version forever. It includes the classic desktop apps (Word, Excel, PowerPoint, Outlook). No cloud storage, and it does not auto-upgrade to future versions.
- Microsoft 365 (subscription) — you pay yearly and always get the latest apps, plus OneDrive cloud storage and use across multiple devices. Stop paying and the apps go read-only.
Which is cheaper long-term?
Over 3–4 years, a one-time Office 2021 (₹150–₹1,683) is cheaper than renewing a subscription every year — as long as you don’t need the newest features or cloud storage. If you value always-latest apps, OneDrive and multi-device access, Microsoft 365 is the better fit. Many people simply buy the lifetime key.
Are these Office licenses genuine?
Yes — they activate directly with Microsoft and show a genuine activation status. Delivery is instant (on-screen + email), with a replacement warranty for the license validity.
