Frequently Asked Questions

Common questions and detailed answers regarding calculations, formulas, and usage.

Why use ConvertSheet instead of Omni Calculator for financial math?

Omni Calculator shows numbers on screen, but ConvertSheet allows you to export full 360-month amortization schedules and compound growth balances directly to Microsoft Excel workbooks for your personal budget.

Can I embed ConvertSheet calculators on my own blog?

Yes. Every ConvertSheet calculator includes an Embed button with a ready-to-use responsive HTML iframe snippet for your website.

Is my personal financial data tracked or stored?

No. All income, loan balance, and mortgage numbers remain strictly in your browser. Nothing is ever sent to any remote database.
