Own funds (best)
No interest cost. Use for the fixed cost buffer component. Minimum 30–40% of total WC should be own funds.
Cash Credit / OD limit
Revolving bank line at 10–13% p.a. Draw and repay as needed. Best for inventory and debtor float. Apply with 2 years of ITR + GST returns.
MUDRA Kishor / Tarun
₹50k–₹10L at 11–14% for micro/small restaurants. Minimal collateral for amounts below ₹10L. Good for early-stage WC.
Working capital = operating cycle requirement (inventory + aggregator float − supplier credit) + fixed cost buffer. Does not include startup capital, fit-out, or equipment costs — use the Startup Cost Estimator for those.

What is working capital and why do restaurants underestimate it

Working capital is the cash a business needs to fund its day-to-day operations — the gap between when you pay for inputs (ingredients, rent, payroll) and when you collect revenue. For most businesses, this is: inventory + debtors − creditors. For Indian restaurants in 2025, there is a fourth critical component: aggregator payout lag.

A restaurant doing ₹6L/month with 40% of revenue via Zomato/Swiggy and a 10-day payout cycle has approximately ₹80,000 permanently trapped in the aggregator float — money earned but not yet settled. This is cash that cannot be used to pay vendors, staff, or rent. As aggregator volumes grow, so does this float.

Most new restaurant owners plan for startup capital (fit-out, equipment, advance rent) but overlook working capital. They run out of cash 2–3 months after opening — not because the business is losing money, but because cash is tied up in inventory, payout lag, and the ramp-up period before revenue reaches break-even. This is one of the most common causes of early restaurant failure in India.

The operating cycle for a restaurant

The operating cycle measures the time between paying for inputs and collecting revenue:

  1. Pay supplier for vegetables, proteins, dry goods (cash or credit)
  2. Ingredients sit in inventory (1–7 days, depending on stock policy)
  3. Ingredients are used in food preparation → dish is sold
  4. Cash sale: revenue collected immediately (dine-in, counter)
  5. Aggregator sale: revenue collected after 7–14 day payout cycle
  6. Corporate/catering credit sale: revenue collected after 15–30 days

Working capital requirement = the cash needed to bridge steps 1–6 while the cycle repeats daily. The longer the cycle and the higher the revenue, the more working capital is locked up.

Strategies to reduce operating cycle and therefore working capital requirement:

  • Reduce stock days: Just-in-time procurement from local vendors reduces inventory float. Requires reliable vendor relationships and disciplined reorder management.
  • Extend supplier credit: Negotiate 15–30 day credit terms with distributors. Even 7 days of credit on COGS significantly reduces WC requirement.
  • Reduce aggregator dependency: Direct ordering via WhatsApp, your own app, or ONDC gives you immediate settlement vs 7–14 day payout lag.
  • Avoid credit sales: Unless you have a reliable corporate client base, avoid extending credit. Each rupee of credit sales locked in debtors is a rupee of working capital consumed.

Fixed cost buffer: the safety net most operators skip

Beyond the operating cycle, a restaurant needs a cash buffer to cover fixed costs during: revenue ramp-up (first 3–6 months), slow seasons, unexpected repairs, or short-term revenue dips. The recommended buffer is 2–3 months of fixed costs for a new restaurant, reducing to 1 month once the business is stable and has access to a bank overdraft line.

For a restaurant with ₹3L/month in fixed costs, a 2-month buffer = ₹6L permanently parked as cash reserve. This should be kept in a current account or sweep FD — not deployed into inventory or fit-out — because its purpose is liquidity, not yield.

Where this fits

  • Startup cost estimator — startup capital (fit-out, equipment, deposits) is separate from working capital; both must be funded before opening
  • Loan EMI calculator — if borrowing to fund working capital, compute EMI here and include it in your fixed cost buffer calculation
  • Break-even calculator — your working capital buffer must last at least until break-even; if break-even is month 6, you need 6 months of fixed cost coverage
  • Cash book — track actual cash inflows and outflows daily; your working capital buffer is depleted faster than you think if cash discipline is poor
  • Aggregator margin calculator — understand the full cost of Zomato/Swiggy including the payout lag; high aggregator dependency increases working capital requirement
