Compare with Alternatives

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Provides the ISPMT financial function in WPS Spreadsheets, with formula entry in cells or the formula bar and syntax prompts during input.	Microsoft Word officially supports formulas in table cells for calculations and logical comparisons, but the documented workflow is centered on document tables rather than a spreadsheet-first financial function workflow.	Google Sheets is presented as an online spreadsheet product for managing, visualizing, and analyzing data, and Google states that Gemini in Sheets can help create formulas for calculations.	Notion formulas work on database properties, built-ins, and functions to perform calculations inside databases rather than traditional spreadsheet cells.	Adobe Acrobat supports calculations for PDF form fields, mainly for form totals and field relationships instead of spreadsheet-style financial functions.
WPS Advantages	Advantage: Directly aligned with spreadsheet cell formula entry on Windows for financial calculations. Advantage: Typing `ISPMT(` can surface syntax guidance while building the formula.	Compared with WPS: official guidance focuses on Word table formulas and field-code style calculations, so the documented scenario is less centered on spreadsheet financial modeling.	Compared with WPS: stronger emphasis on cloud collaboration and AI-assisted spreadsheet work; WPS is more direct for local desktop spreadsheet formula entry in a traditional office workflow.	Compared with WPS: formula logic is tied to database properties and automations, not a standard worksheet cell formula experience.	Compared with WPS: calculation features are designed for PDF forms, not for spreadsheet-based financial analysis in worksheet cells.

Overall Conclusion

If your main goal is to enter a financial function directly in a spreadsheet on Windows and get a result in the same worksheet workflow, WPS offers a straightforward path. The other products also support calculation features, but their official documentation focuses more on document tables, cloud collaboration databases, or PDF form scenarios.
