How much working capital does a new business need?
Initial working capital covers the gap between spending money (salaries, rent, inventory) and collecting it (customer payments). If customers pay in 60 days and you spend ₹15 lakh a month, you need at least ₹30 lakh just to bridge the cycle - before any buffer.
The most common startup cash mistake is funding only the operating cycle with no buffer. Add 2-3 months of expenses on top: late payments, seasonal dips, and surprise costs are certainties, not risks.

This calculator estimates the cash a new business needs before revenue collections become reliable. It combines two parts: the operating cycle capital (monthly expenses × months until customers pay) and a safety buffer (extra months of expenses for the unexpected).

Set your customer payment cycle - upfront for B2C, typically 30-90 days for B2B.

Choose a safety buffer - 2-3 months is the sensible minimum for a new business.
- 4
Read the total initial working capital you should have before launch.
Where startups get initial working capital
Founder capital and equity
The default source, but expensive - every rupee of working capital funded by equity is dilution spent on operations, not growth.
Working capital loans
Once you have 6-12 months of revenue, unsecured working capital lines become available - and they scale with revenue.
Invoice financing
If B2B customers pay slowly, financing invoices converts the receivable into same-week cash.
Supplier credit
Negotiated payment terms with suppliers are free working capital - often the cheapest source available.
