Contractors win tenders and still lose money more often than the industry likes to admit — usually because the margin never separated overhead, risk and profit in the first place.
A tender bid that wins comfortably and still turns out unprofitable is one of the most common — and most avoidable — failure patterns in Indian construction. It rarely happens because the direct costs (material, labour, equipment) were mispriced. It happens because the margin on top of those costs was never explicitly split into what it actually needs to cover.
A single margin percentage usually has to cover three separate things:
Under pressure to win, it is easy to shave the "margin" number down to whatever makes the bid competitive — without separating which component is being cut. Cutting into contingency or overhead recovery, rather than pure profit, means the project may show a healthy bid margin on paper while carrying essentially zero real buffer against anything going wrong.
As a starting point, treat 10-13% combined margin as a floor for typical Indian SMB contractor work — adjusting upward for higher-risk projects (unfamiliar site conditions, tight schedules, volatile-price materials) and refusing to bid meaningfully below that floor even when competitive pressure is high. A tender won below the floor is not a win; it is a bet that nothing will go wrong.
The other lever contractors underuse is their own project history. Comparing a new tender's direct cost assumptions against actual costs from similar past projects — rather than optimistic fresh estimates — routinely catches unrealistic assumptions before they get baked into a losing bid.
Contractors who price tenders consistently well never negotiate a single "margin" number under pressure — they defend the three components (overhead recovery, risk contingency, target profit) separately, so a competitive cut comes visibly out of target profit rather than silently eating into the buffer meant to absorb ordinary execution friction. The second habit worth building is grounding direct cost assumptions in actual costs from comparable completed projects rather than fresh optimistic estimates — it is usually the fastest way to catch an unrealistic bid before it is submitted.
