What it actually tells you
It helps compare operating businesses with different financing structures. A sales multiple still cannot distinguish valuable growth from growth that consumes cash.
THE CALCULATION
Formula
EV/Sales = enterprise value ÷ revenue over a stated period
A simple example
Educational example: Equity value of ₹900 crore plus ₹300 crore debt less ₹100 crore cash gives simplified EV of ₹1,100 crore. With ₹550 crore revenue, EV/Sales is 2×. Other claims would require additional EV adjustments.
All figures in this guide are illustrative teaching examples.
Read both sides of the number.
What high can mean
A high ratio can price in stronger eventual operating margins, growth or capital efficiency. Small sales at an early-stage firm can also inflate it.
What low can mean
A low ratio can reflect thin margins, declining demand or heavy reinvestment requirements. It is not proof of undervaluation.
When a high reading may be justified
A company with durable pricing power and low reinvestment needs can justify more per rupee of sales than a capital-intensive competitor.
When a low valuation may be dangerous
A low sales multiple may conceal obsolete products or a business that cannot earn its cost of capital even at normal margins.
BEYOND THE TEXTBOOK
Professional interpretation
Estimate sustainable operating margins and reinvestment before judging the multiple. Reconcile debt, leases, minority interests and cash in EV, then use revenue for the same consolidated operating perimeter.
Compare in context.
Live comparison data is not connected. No company or market averages are supplied here.
Sector context
Banks and insurers generally require other frameworks because financing liabilities are part of operations. Retail and software need very different margin assumptions.
Industry context
Distribution businesses can produce huge sales at tiny margins; licensing businesses may report much smaller sales with higher margins.
Historical comparison
Use contemporaneous EV and the revenue period then available. Separate changes from acquisitions, disposals and principal-versus-agent accounting.
Peer comparison
Align lease treatment, revenue recognition, geography and business mix. If EV includes minority claims, revenue should ordinarily include the corresponding consolidated subsidiaries.
Limitations
Debt and cash values may be stale between reports. EV/Sales ignores taxes, working capital and capital expenditure; it is not a discounted cash-flow model.
Common investor mistakes
Comparing a net-revenue platform with a gross-revenue retailer; using equity value while labelling it enterprise value.
Example interpretation
A 2× EV/Sales reading becomes useful only after asking what operating margin and reinvestment rate the business can sustain. Test the resulting cash flow against the price.
Questions worth asking
Does EV/Sales remove all leverage risk?
No. It improves the valuation numerator but does not eliminate refinancing risk for shareholders.
Can EV be negative?
Yes under some definitions when cash exceeds equity value and other claims. Check cash availability and all obligations carefully.
Analyse these together
A single ratio cannot capture the business. Combine it with:
