The Challenge of Cumulative Costs

A single product's final cost is rarely its listed price. It's layered with expenses that arrive at different times:

  • Product cost from supplier
  • Shipping & freight charges
  • Customs duties and taxes
  • Payment processing fees
  • Warehousing and handling

When you purchase the same item across multiple shipments, each batch may have a slightly different landed cost. Without proper tracking, your pricing and profit margins are based on guesses, not data.

How the MuleBuy Spreadsheet Solves This

The spreadsheet is engineered to build a complete financial picture over time. Here’s its core methodology:

1. Granular Fee Logging

Each shipment is logged with its own dedicated row or section. You input not just the unit price, but every associated fee

2. Dynamic Cumulative Totals

As you add new shipments, the spreadsheet automatically sums cumulative totals✅ Total Quantity Purchased:✅ Total Money Spent:

3. Automatic Average Cost Calculation

This is where precision emerges. The tool uses a simple but powerful formula: Average Cost Per Unit = Total Money Spent / Total Quantity Purchased This figure updates automatically with each new shipment entry, giving you a real-time, accurate benchmark.

  • Confident Pricing:
  • ROI Analysis:
