Batch Size Calculator
Calculate optimal batch sizes for manufacturing and production. Determine the most cost-effective production quantities based on demand, setup costs, and holding costs.
Step 1: Production Parameters
units
Understanding Batch Production
Optimal batch size balances setup costs against holding costs. Larger batches reduce setup frequency but increase inventory costs.
Step 2: Production Details
units/day
units/day
days
Economic Production Quantity
The EPQ formula calculates the optimal batch size that minimizes total inventory costs by balancing setup and holding costs.

Batch Size Cost Analysis
Economic Production Quantity Formula
EPQ = √[(2 × D × S) / (H × (1 – d/p))]
Where: D = Annual demand, S = Setup cost per batch, H = Holding cost per unit per year, d = Daily demand rate, p = Daily production rate.
