Where did it actually go?

Most Malaysian contractors don't lose money on bad pricing — they lose it to site changes nobody logged and materials nobody reconciled. Plug in your numbers below and see roughly how much of this project's margin is quietly leaking, based on how you're currently tracking it.

How this estimate is calculated

We're not going to pretend this is an audit. It's a directional estimate built from leak patterns commonly seen in Malaysian trade and renovation projects that rely on manual tracking — meant to make an invisible problem visible, not to replace your actual books.

Tracking MethodTypical Unbilled Variation LeakTypical Material/Logistics Slippage
Excel / Google Sheets~2% of contract value~1.5% of material cost
WhatsApp Groups~4% of contract value~3% of material cost
Pocket Notebook~4% of contract value~3% of material cost
Just Memory / Verbal~5% of contract value~4% of material cost

Longer projects add a small additional variation-leak allowance beyond 6 months, since verbal changes are more likely to be forgotten the longer a job runs. Your actual numbers will differ based on your team, your client, and how disciplined your current process already is — use this as a prompt to check your real numbers, not as a final figure.
