Tooling, Fixtures, Dies & Mold Economics calculator
Tool Refurbishment Payback Calculator
Determine whether a die or mold refurbishment can repay its cost before retirement. Use the restoration quote, measured scrap and rework reductions, incremental upkeep, expected service life and approval limit.
What this calculator does
- Check whether the refurbishment investment recovers within your permitted payback and remaining useful program life.
Formula used
- Annual net savings = annual gross savings − annual incremental upkeep
- Simple payback = investment ÷ positive annual net savings
- Remaining net benefit = annual net savings × remaining life − investment
- Target headroom = maximum allowed payback − simple payback
- Life headroom = remaining useful program life − simple payback
Inputs explained
- Refurbishment Investment: Installed quote including qualification and directly attributable startup costs.
- Annual Gross Savings: Annual labor, scrap or rework cash savings against the baseline.
- Annual Incremental Upkeep: Incremental annual support costs on the same comparison basis.
- Remaining Useful Program Life: Remaining tool service or committed program life, whichever is shorter.
- Maximum Allowed Payback: Your organization’s permitted recovery period for this investment.
How to use the result
- Best suited to tool restoration Decision, scrap reduction investment.
- Discounting, tax, financing and resale proceeds are excluded. Uneven yearly savings require a separate cash-flow schedule.
Current U.S. benchmarks
- The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
- The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
Common questions
- Which scrap savings can I credit to refurbishment? Use the reduction attributable to the restored tool at comparable production volume and material prices. Separate improvements caused by unrelated process changes.
- How do I estimate post-refurbishment upkeep? Compare annual maintenance after restoration with the baseline used in your savings estimate. Enter additional support costs without counting an already deducted repair charge twice.
- Can the original rated life justify the refurbishment? No. Enter the remaining service life supported by the inspection and restoration plan. The recovered tool may not regain its original rated life.
- What if the tool produces only seasonal work? Use annual savings that reflect its actual operating months. If yearly volumes change materially, compare a dated cash-flow schedule instead of assuming steady recovery.
