- Keep one calculator window open while working in spreadsheets or reports.
Common issues and fixes
Calculator will not open
- Restart your computer first.

- Go to Settings > Apps > Calculator > Advanced options, then click Reset.
Wrong decimal format or number separators
Check Region settings in Windows. Decimal and thousands separators follow your locale.

Search for “Calculator” again in Start. If needed, reinstall from Microsoft Store.
Should you use third-party calculator apps?
For most users, the built-in Windows 10 calculator is enough. Third-party apps only become useful if you need niche features like equation solving, graph plotting, or financial modeling beyond what Standard/Scientific modes provide.
