Most people assume Excel is a one-time purchase you buy once and own forever. They’re wrong. Microsoft killed that model in 2013 — and if you paid $169.99 for Excel 2021 thinking you’d never pay again, you just bought software that won’t get security updates after October 2026.
Quick Answer
Excel for PC costs nothing (web version), $7/month (Microsoft 365 Personal), $10/month (Business Standard), or $169.99 one-time (Office 2021 — unsupported after 2026). There’s no standalone Excel purchase — it only ships as part of Office suites or Microsoft 365 subscriptions.

Let’s say your finance intern Sarah Chen needs to build a budget tracker for Acme Corp’s Q3 marketing spend — but her laptop runs Windows 10 Home and she doesn’t have admin rights to install software. She uses Excel for Web.
She opens office.com, signs in with her work Microsoft account, clicks the Excel tile, and creates a new blank workbook. In A1:E1, she types: Month, Channel, Spend, Target, Variance. Then fills rows 2–7:
| A | B | C | D | E |
|---|---|---|---|---|
| Jul-24 | $12,400 | $14,000 | =C2-D2 | |
| Aug-24 | $18,950 | $16,500 | =C3-D3 | |
| Sep-24 | Google Ads | $21,300 | $22,000 | =C4-D4 |
| Oct-24 | Webinars | $8,720 | $9,000 | =C5-D5 |
| Nov-24 | Events | $33,100 | $28,500 | =C6-D6 |
She copies E2 down to E6 using Ctrl+D. No installation. No credit card. But when she tries to add a PivotTable? Grayed out. That’s the wall — web Excel doesn’t support them. Her workaround: export to .xlsx, email it to her manager who has desktop Excel, and ask them to generate the summary.
Method 2 Deep Dive
Now imagine Rajiv Patel, IT manager at Nexus Logistics, rolling out Excel to 42 field reps. He chooses Microsoft 365 Business Standard — not because it’s cheaper per seat than Personal, but because he needs centralized license management and audit logs.
He logs into admin.microsoft.com, goes to Users > Active users, selects all 42 reps, clicks Edit product licenses, checks Microsoft 365 Business Standard, and saves. Within 15 minutes, each rep sees Excel appear in their Start menu — no downloads, no keys.
Here’s the counterintuitive tip: Rajiv doesn’t assign Excel alone. He assigns the full suite — even though reps only open Excel. Why? Because Microsoft blocks standalone Excel licensing. You *cannot* buy Excel by itself for PC. Ever. The cheapest path to desktop Excel is Microsoft 365 Personal — but that lacks admin controls. So for any team, Business Standard is often the *only* viable option — even if Word and PowerPoint go unused.
Rajiv tests deployment by opening Excel on his test laptop (Windows 11 Pro), then presses Alt+F-T to open Options → Save → sets Default file location to \\fileserver\marketing\templates. That ensures every new workbook saves directly to the shared drive — no accidental local saves.
Cheat Sheet
| Task | Action | Shortcut | Notes |
|---|---|---|---|
| Open Excel for Web | Go to office.com → Sign in → Click Excel | N/A | No install needed; works in Edge, Chrome, Firefox |
| Check your license type | File → Account → Under Product Information | Alt+F+A | Shows "Microsoft 365 Apps" or "Office 2021" |
| Switch from 2021 to M365 | Uninstall Office 2021 → Go to account.microsoft.com → Install | Win+R → appwiz.cpl | Don’t skip uninstall — coexistence causes ribbon conflicts |
| Cancel free trial safely | account.microsoft.com/services → Find trial → Manage → Cancel | Alt+F+C | Canceling in Settings *is not enough* — must do it in Services |
| Find your product key (2021) | Check original email receipt or physical card — not in Excel | N/A | Product keys aren’t stored in registry or Excel — lost key = lost license |
