Frequently Asked Questions
Can I create a professional invoice for free?
Yes. The Invoice Generator lets you add your business details, client info, line items, tax rate, and payment terms — then export a print-ready PDF with no watermark and no account required.
How does the EMI calculator work?
Enter the loan amount, annual interest rate, and loan tenure in months. The calculator uses the standard reducing-balance formula to show monthly EMI, total interest paid, and total repayment amount.
Does the GST Calculator handle IGST?
Yes. For inter-state transactions, toggle the IGST option and the calculator shows the full IGST amount. For intra-state, it splits into CGST + SGST automatically.
What business tools are free to use commercially?
All tools on this site — Invoice Generator, EMI Calculator, GST Calculator, ROI Calculator, Currency Converter, and SIP Calculator — are free for personal and commercial use with no attribution required.
Is the SIP calculator accurate for mutual fund projections?
The SIP Calculator uses the standard compound interest formula for monthly investments and is accurate for fixed return rate projections. Actual mutual fund returns vary — use this for indicative planning only.
