Procurement Lead-Time Carrying Cost: Calculate additional inventory carrying cost caused by longer supplier lead times.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Procurement Lead-Time Carrying Cost to answer this question: calculate additional inventory carrying cost caused by longer supplier lead times? Enter Daily material usage, Unit material cost, Current lead time days, and 2 other inputs; the calculator shows Annual incremental carrying cost. Try changing one number and watch what happens to Annual incremental carrying cost. The answer tells you Annual incremental carrying cost.
Age 15Explain it to a 15-year-oldConnect it to the formula
Longer lead time can also require safety stock; demand variability and service targets are excluded here. The rule is Incremental inventory = daily usage × lead-time increase × unit cost. Its input values are Daily material usage, Unit material cost, Current lead time days, Alternative lead time days, Annual inventory carrying rate (%), and the main result is Annual incremental carrying cost. Try changing one number and watch what happens to Annual incremental carrying cost.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Incremental inventory = daily usage × lead-time increase × unit cost, evaluated from Daily material usage, Unit material cost, Current lead time days, Alternative lead time days, Annual inventory carrying rate (%) to produce Annual incremental carrying cost. Longer lead time can also require safety stock; demand variability and service targets are excluded here. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Calculate additional inventory carrying cost caused by longer supplier lead times.
Why the business model works
Longer lead time can also require safety stock; demand variability and service targets are excluded here.
Inputs and operating assumptions
This model uses Daily material usage, Unit material cost, Current lead time days, Alternative lead time days, Annual inventory carrying rate. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Incremental inventory = daily usage × lead-time increase × unit cost
What the calculator produces
The primary output is Annual incremental carrying cost; it also exposes Incremental inventory investment, Additional units held. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
