How does Aha Planner calculate my working capital and the sector benchmark?

Aha Planner measures your working capital from your balance sheet: receivables, inventory and other current assets, less payables and other current liabilities. The sector benchmark applies your industry's working-capital-to-revenue ratio, from Damodaran at NYU Stern, to your revenue. Working capital is not part of your operating cash requirement, so it does not change your indicative valuation.
