What Is a Stock Valuation Calculator?
A Stock Valuation Calculator helps you determine the Cost of Goods Sold (COGS) and the value of remaining inventory using three standard accounting methods: FIFO (First In, First Out), LIFO (Last In, First Out), and Weighted Average Cost (WAC). Each method produces different COGS and ending inventory values, which directly affects your gross profit. This tool lets you enter multiple purchase batches at different costs and see how each method allocates those costs to sold vs. remaining units.
How to Use the Stock Valuation Calculator
Step 1 — Choose Valuation Method
Select FIFO (First In, First Out), LIFO (Last In, First Out), or Weighted Average Cost from the toggle. Each method produces a different COGS and remaining inventory value.
Step 2 — Enter Purchase Batches
Add each stock purchase batch with its quantity and unit cost. Enter batches in chronological order (oldest first) — this matters for FIFO and LIFO calculations.
Step 3 — Enter Units Sold & Read Results
Type the total units sold. The calculator shows COGS, remaining units, remaining inventory value, and average cost per remaining unit instantly.

Frequently Asked Questions
What is FIFO inventory valuation?
FIFO (First In, First Out) assumes the oldest stock is sold first. During rising prices, FIFO results in lower COGS and higher ending inventory value, producing higher gross profit.
What is LIFO inventory valuation?
LIFO (Last In, First Out) assumes the newest stock is sold first. During rising prices, LIFO results in higher COGS and lower ending inventory value. Note: LIFO is not permitted under IFRS (used in India); it is allowed under US GAAP.
What is Weighted Average Cost (WAC)?
WAC divides total inventory cost by total units to get an average cost. All units — sold and remaining — are valued at this same average. This smooths out price fluctuations across batches.
Which method should I use?
Most Indian businesses use FIFO or WAC as LIFO is not permitted under Indian Accounting Standards (Ind AS / IFRS). WAC is simpler for businesses with many small purchases; FIFO is preferred when you actually sell older stock first (e.g. perishables).
What is COGS?
COGS (Cost of Goods Sold) is the direct cost attributable to the units sold. It is deducted from revenue to calculate gross profit on the income statement.
