Understanding Inventory Valuation — Lessons from My Intuit Academy Practice
In my bookkeeping training with Intuit Academy, I’ve been exploring how inventory valuation affects a business’s profit, tax, and overall financial accuracy.
Inventory might look simple — just goods on a shelf — but how you value it can completely change your financial statements.
During my mock practice this week, I learned how three key methods — FIFO, LIFO, and Weighted Average Cost (WAC) — affect both the Balance Sheet and Income Statement differently.
Here’s what stood out:
FIFO (First-In, First-Out)
The first goods purchased are the first sold. When prices rise, COGS is lower and profit looks higher.
It reflects a more current and realistic inventory value.
LIFO (Last-In, First-Out)
The last goods purchased are the first sold.
When prices rise, COGS is higher and profit is lower — meaning lower taxable income.
It’s a practical method under U.S. GAAP, though not allowed under IFRS.
Weighted Average Cost (WAC)
Every item is valued at an average cost per unit. This smooths out price fluctuations and keeps reporting consistent and simple.
I practiced recording these transactions for a mock candle-making business — calculating how wax and wicks move from raw materials to finished goods and finally to cost of goods sold.
It amazed me how the same inventory could produce three different profit outcomes, depending on the valuation method used.
My Takeaway:
Inventory valuation isn’t just about tracking what’s left in stock — it’s about telling the financial truth of a business. Each method reveals a different perspective, but the goal remains the same: accuracy, fairness, and consistency.
Every week with Intuit Academy strengthens my confidence and attention to detail.
Learning how these principles connect to real-world decision-making is what makes this journey truly rewarding.
