Contract Manufacturing, Job Shop Quoting & Make-to-Order calculator
Re-Quote Impact Calculator
Re-Quote Impact tells a job shop how much money is actually on the table when a part has to be re-priced mid-program, after a material surcharge, an engineering change, or a tooling cost the original quote never carried. Estimators and account managers use it to decide whether a re-quote is worth the friction with the customer and to set a realistic recovery target before the negotiation starts. The metric separates gross exposure from what you can credibly claw back once you account for scope and customer goodwill. On a contract-manufacturing floor this is the difference between absorbing a margin hit silently and recovering most of it through a documented change order.
What this calculator does
- Estimate cost exposure from customer re-quotes and drawing revisions.
- deciding whether a re-quote needs a price change, schedule change, or customer approval
- It computes the recoverable dollar impact of a re-quote by multiplying the cost change per unit across the affected quantity, then discounting for the share of scope inside the revision and the share you expect the customer to accept.
Formula used
- gross re-quote impact before recovery = changed cost per affected unit × affected quote or order quantity
- recoverable re-quote impact = gross re-quote impact before recovery × re-quote scope included × expected customer recovery
Inputs explained
- Changed cost per affected unit:
- Affected quote or order quantity:
- Re-quote scope included:
- Expected customer recovery:
How to use the result
- Use it the moment a cost driver shifts after a quote is locked, a steel surcharge, a new finishing operation, or a revised tolerance, and you need a defensible number before reopening price with the customer.
- It assumes a single uniform cost delta per unit; if the change hits different part numbers or operations at different rates, run it per line rather than blending them into one average.
Current U.S. benchmarks
- The U.S. prime lending rate is 6.75% (Federal Reserve via FRED, 2026-07-02). Payback and financing math should start from today's rate, not a remembered one.
Common questions
- How do you calculate re-quote impact? Multiply the changed cost per affected unit by the affected quantity to get gross impact, then multiply by the share of scope included and your expected customer recovery. With $9.40/unit across 520 units, 100% scope and 80% recovery, the gross impact is $4,888 and the recoverable impact is $3,910.40.
- What is the difference between gross and recoverable re-quote impact? Gross impact ($4,888 in the example) is the full cost swing before any haircut. Recoverable impact ($3,910.40) is what you realistically collect after subtracting scope you did not revise and the portion the customer will not absorb.
- What is a good customer recovery percentage on a re-quote? For a documented, contract-backed change driven by a verifiable cost (a surcharge or a customer-requested change), 80-100% recovery is reasonable. Discretionary or goodwill-sensitive accounts often land at 50-75%, which is why the field is a separate lever.
- Why is re-quote scope a separate input from quantity? A program may have 520 units affected by a cost change but only part of the line items inside the revised scope. Scope below 100% carves out units the customer never agreed to reopen, so you do not overstate what you can bill.
- How much am I leaving on the table at 80% recovery? In the worked example, $977.60 is the re-quote impact not recovered, the 20% the customer is not expected to absorb. That figure is your concession, and it should be visible before you commit to the price.
