Frequently Asked Questions

What is the difference between CTC and in-hand salary?
CTC (cost to company) is your total package including employer PF, gratuity and benefits, while in-hand salary is what actually reaches your bank after PF, professional tax and TDS. In-hand is typically 70-85% of CTC. The CTC to In-Hand calculator breaks this down.
How is gratuity calculated in India?
For employees covered by the Payment of Gratuity Act, gratuity is (last drawn salary x 15/26) x years of service, payable after 5 years of continuous service. Up to 20 lakh is tax-exempt. Use the Gratuity calculator for your amount.
What is the difference between IRR and NPV?
NPV gives the value a project adds in today’s rupees at a chosen discount rate, so positive NPV means it is worth doing. IRR is the discount rate at which NPV is zero, expressed as an annual return. Both use the same cash flows; use them together for investment decisions.
When do I need GST registration for my business?
GST registration is generally mandatory once turnover crosses 40 lakh for goods or 20 lakh for services (20 lakh and 10 lakh in special-category states). Below that it is voluntary. Inter-state supply and e-commerce may require registration regardless of turnover.
How much working capital does my business need?
Working capital is current assets minus current liabilities, the money needed to fund day-to-day operations. The right amount depends on your operating cycle, how long cash is tied up in inventory and receivables. The Working Capital calculator helps you size it.
