Mastering the Acid-Test Ratio

How to calculate acid-test ratio for e-commerce businesses?

1. Gather balance sheet data: cash ($20,000), AR ($15,000), marketable securities ($5,000), current liabilities ($25,000)
2. Apply the formula: (Cash + AR + Securities) / Current Liabilities = ($20k+$15k+$5k)/$25k = 1.6
