What this planner helps you decide
Best for
Operators evaluating a process change from entered implementation cost and benefits.
Outputs
Annual savings, capacity value, net benefit, payback and return.
Start here
Separate measured time or cost savings from unproven capacity value, then test both explicitly.
Use a different tool when: Do not use this to choose the highest-contribution use of a constrained operating resource; use Capacity Constraint Profit Planner for that decision. Use this tool to test the savings, capacity value and payback of a process improvement.
Profit & break-even
Process Improvement Payback: annual savings
Annual savings, capacity value, net benefit, payback and return.
Amounts use the same currency as your inputs. No currency conversion is performed.
Process Improvement Payback
Reconcile labour time saved, incremental throughput contribution and recurring cost before testing the payback of an improvement investment.
Your numbers stay in this browser
Enter the one-off implementation cost. Use one consistent ex-tax currency basis.
Enter measured hours used by the current process.
Enter the expected share of baseline hours removed by the scenario.
Include wages and relevant employer on-costs per hour. Use one consistent ex-tax currency basis.
Enter additional whole or fractional units served in the same period.
Enter revenue less avoidable cost for one added unit. Use one consistent ex-tax currency basis.
Enter added operating cost for each benefit period. Use one consistent ex-tax currency basis.
Decision result
Review the operating threshold and incremental comparison on the same entered capacity, cost and demand basis.

Process Improvement Payback: annual savings
Measured savings and optional capacity value should remain separate so payback is not overstated.
Formula summary
- Primary formula
- upfront cost / positive net benefit per period.
Data used here
- The estimate uses your inputs and the general business formula documented in the methodology.
Decision checks
Stress-test the decision
Retest lower adoption, delayed savings and a higher implementation cost.
When this estimate can be misleading
- Volumes, rates, capacity, time, costs and contribution are your records or scenarios; no benchmark or demand forecast is embedded.
- Keep all money and operating records on one consistent ex-tax basis and decision period.
- Incremental comparisons exclude disclosed sunk cost and do not guarantee demand, delivery capacity or a commercial outcome.
- This is educational business decision support, not accounting, tax, legal or financial advice.
- Measured savings and optional capacity value should remain separate so payback is not overstated.
