Mathematics for Retail Buying Solutions with Step by Step Calculations

Apply margin equations immediately: gross margin equals sales minus cost, then divided by sales. Use this formula on each pricing task to confirm percentage targets such as 40% or 55% without rounding early.

Markup tasks rely on cost-based ratios. Divide planned price by unit cost to check markup percent, then compare against department targets. Use decimal precision to three places to avoid drift across multi-item worksheets.

Inventory turnover problems require annual sales divided by average stock value. Keep beginning and ending stock figures separate, then average them prior to calculation. This method prevents inflated turnover rates.

Open-to-buy exercises depend on planned sales, planned reductions, and beginning stock. Subtract expected stock levels from planned stock targets to find remaining purchasing capacity. Record each step clearly to match grading criteria.
