How is GST calculated for a business in India?
For intra-state supply: GST = CGST (half rate) + SGST (half rate). For inter-state supply: GST = IGST (full rate). Formula: GST amount = Invoice value × GST rate / 100. Reverse (to extract base price from GST-inclusive): Base = Inclusive price / (1 + rate/100). Under GST 2.0 (September 2025), the rate structure simplified to 5%, 18%, and 40% from the earlier four-tier (5/12/18/28%) structure.
What is the presumptive tax rate for small businesses under Section 44AD?
Section 44AD (for businesses, not professionals): turnover ≤ ₹3 crore (if 95% cashless receipts) or ≤ ₹2 crore (otherwise). Deemed profit: 8% of turnover (cash) or 6% (digital payments). No books of accounts required, no audit. File ITR-4 (Sugam). For professionals (doctors, lawyers, IT consultants, CAs): use Section 44ADA — deemed profit 50% of gross receipts up to ₹75 lakh.
How do I calculate import duty on goods entering India?
Total import cost = CIF (Cost + Insurance + Freight) + Basic Customs Duty (BCD) + Social Welfare Surcharge (SWS, 10% of BCD) + IGST (applied on CIF + BCD + SWS). Example: ₹1L CIF laptop (HSN 8471, BCD 0%, IGST 18%): Total = ₹1L + ₹0 BCD + ₹0 SWS + ₹18,000 IGST = ₹1,18,000. Use the Import Duty Calculator with the correct HSN code for accurate computation.
What is working capital and how do I calculate it?
Working capital = Current Assets – Current Liabilities. Current assets: cash, debtors (receivables), inventory. Current liabilities: creditors (payables), short-term loans. Positive working capital means you can fund day-to-day operations. The working capital cycle (days) = Inventory days + Debtor days – Creditor days. For a business with 45-day inventory, 30-day debtor, and 15-day creditor cycles: WC cycle = 45+30–15 = 60 days of revenue needs funding.
How is profit margin calculated for a business?
Gross profit margin = (Revenue – COGS) / Revenue × 100. Net profit margin = Net profit after tax / Revenue × 100. EBITDA margin = EBITDA / Revenue × 100. For a trading business with ₹50L revenue, ₹35L COGS, ₹8L operating expenses, ₹1.5L tax: Gross margin = 30%; Net margin = 11%. Use the Profit/Loss Calculator for multi-year comparison and breakeven analysis.
