Free Tool · CIDB G1–G5

Price your tender with your overhead, contingency and profit built in — not bolted on after.

Enter your costs once. This works out your gross tender price the way a QS would — margins calculated on the final price, not marked up on cost — and flags it instantly if it breaches your CIDB grade ceiling or puts your cash flow at risk.

Your net profit margin is less than or equal to your retention rate. Your entire paper profit will be locked up by the client until the Defect Liability Period closes.
The homeowner's final handover holdback exceeds your profit margin. You'll be funding the final phase of this renovation out of your own pocket.

This tells you what to price. KonstrakOS tracks whether you're actually hitting it — real costs against this exact budget, updated as you buy and bill.

How the numbers are worked out

This uses the margin-on-price method — your overhead, contingency and profit are guaranteed as a share of the final tender price, not marked up on cost. That's the same approach a quantity surveyor uses when they say "I want a 10% margin" and mean it on revenue, not on cost.

Contingency is fixed at 4% for commercial projects (material price volatility) and 9% for residential (scope drift from fussy clients). The CIDB levy of 0.125% applies here to commercial projects over RM500,000, matching how it's most commonly invoiced in practice — check your own contract terms, since the levy is technically payable by the project owner on any registered CIDB contract at that value. This tool gives you a pricing structure to sanity-check your own quote against, not a substitute for your own costing discipline or professional advice.
