Storage Cost Calculator
Estimate monthly storage cost per item and its effect on margin. Use this calculator to test a realistic base case, a conservative case, and a best case before making the decision.
How to use this result
This page is designed for planning, not promises. Replace default values with real numbers, include the costs that are easy to forget, and verify marketplace, carrier, tax, or payment rules before taking action.
A good result should survive small changes in assumptions. If a decision only works when fees, returns, shipping, or demand are perfect, it may be too fragile for a real seller workflow.
- Run at least two scenarios before changing price or inventory plans.
- Include return risk, packaging, payment cost, and time where they apply.
- Use official sources when a rate, rule, or obligation matters.
Decision notes
Inventory that sits too long has a real cost even when there is no explicit warehouse bill.
