⚠️ Important Notes About Stock Planning
Understand inventory requirements and safety buffers.
Please Note
Buffer percentages protect against usage spikes and supply delays. Adjust buffer based on volatility (10% for stable usage, 20-30% for variable usage). Monitor actual usage patterns and adjust calculations accordingly.

❓ Frequently Asked Questions About Stock Required
Find answers to common questions about stock calculations.
How is stock required calculated?
►
Stock Required = (Daily Usage × Days) + ((Daily Usage × Days) × Buffer %)
What should my buffer percentage be?
►
10% for stable, predictable usage. 20-30% for variable usage with demand spikes. Increase if supplier lead times are long (>15 days).
How do I account for seasonal variations?
►
Use peak season daily usage for calculations. Increase buffer % during high-variance seasons (20-40%) to prevent stockouts.
Is my data stored?
►
No. All calculations done in your browser. Data never stored on servers.
