Microsoft Office pricing splits into two completely different models: a one-time purchase that you own forever, and a subscription that stops working when you stop paying. The sticker prices from Microsoft look very different from what you can pay through an authorized reseller — and the five-year total cost is where the real difference shows.
Microsoft’s official prices (2026)
| Product | Price | What’s included |
|---|---|---|
| Microsoft 365 Personal | $69.99/year | Word, Excel, PowerPoint, Outlook, 1TB OneDrive — 1 user, 5 devices |
| Microsoft 365 Family | $99.99/year | Same apps — up to 6 users, 5 devices each, 1TB OneDrive per user |
| Microsoft 365 Business Basic | $6/user/month | Web/mobile Office only — Teams, Exchange, SharePoint, 1TB OneDrive |
| Microsoft 365 Business Standard | $12.50/user/month | Full desktop Office + Teams + cloud services — 5 devices per user |
| Office 2021 Home & Student | $149.99 once | Word, Excel, PowerPoint — 1 PC, no Outlook, no Access |
| Office 2021 Home & Business | $249.99 once | Word, Excel, PowerPoint, Outlook — 1 PC |
| Office 2021 Professional Plus | $439.99 once (Microsoft direct) | Full suite: Word, Excel, PowerPoint, Outlook, Access, Publisher, Teams — 1 PC |
| Office 2024 Professional Plus | $439.99+ once (Microsoft direct) | Same as 2021 Pro Plus but current version — longer support window |
What authorized resellers actually charge
Microsoft licenses Office 2021 and 2024 Professional Plus through volume licensing channels. Authorized resellers purchase these licenses in bulk and pass the savings on to individual buyers and businesses. The software is identical — same key, same activation servers, same Microsoft support.
The practical result: Office 2021 Professional Plus from MyLegitKeys costs a fraction of the $439.99 Microsoft direct price, with the same perpetual license, same apps, and the same genuine activation. See current pricing: Office 2021 Professional Plus | Office 2024 Professional Plus.
Total cost over 5 years — subscription vs one-time
| Option | Year 1 | Year 3 total | Year 5 total |
|---|---|---|---|
| Microsoft 365 Personal | $69.99 | $209.97 | $349.95 |
| Microsoft 365 Family | $99.99 | $299.97 | $499.95 |
| Office 2021 Pro Plus (reseller) | One-time — see site | Same — no extra cost | Same — no extra cost |
Hidden costs to factor in
- Microsoft 365 auto-renewal: Subscriptions renew automatically at full price. Easy to forget and overpay for years.
- OneDrive storage: If you rely on Microsoft 365’s 1TB OneDrive and cancel, you drop to the free 5GB tier. You’d need a separate cloud storage plan if you want to maintain that storage.
- Price increases: Microsoft has raised Microsoft 365 prices before — a perpetual license locks in your cost.
- Business per-seat costs compound fast: At $12.50/user/month, a 10-person team on 365 Business Standard costs $1,500/year. Ten Office 2021 Pro Plus perpetual keys from a reseller can be significantly less.
Which version of Office should you buy?
| Your situation | Best option |

| Need latest AI features (Copilot) | Microsoft 365 + Copilot add-on |
| Buying today, planning to keep 5+ years | Office 2024 Pro Plus (longer support window) |
Frequently asked questions
Why is Office so much cheaper from a reseller than from Microsoft directly?
Microsoft sells volume licenses to businesses and authorized partners at bulk rates. Resellers like MyLegitKeys purchase these and pass the discount on. The license is identical — the same key activates against Microsoft’s servers the same way. The difference is purely the sales channel, not the product.
Does the cheaper price mean it’s a gray-market or stolen key?
Not from a reputable authorized reseller. See our guide: Are Third-Party Software Key Sites Legit? — it covers exactly what to look for and how to verify a seller is legitimate.
Is Office 2024 worth the extra cost over Office 2021?
If you’re buying today, Office 2024 has a longer mainstream support window (through 2028 vs 2023 for 2021) and includes newer features. If cost is the priority and you don’t need the latest version, Office 2021 is fully capable for most business use.
Can I get Office for free?
Office Online (web version) is free at office.com with a Microsoft account. It runs in the browser and covers basic Word, Excel, and PowerPoint functionality — no desktop install, no Access or Publisher, limited offline capability. For full desktop Office, a purchase or subscription is required.
