Trade Values Calculator: Worked Examples

These examples use hypothetical estimate units so you can reproduce the arithmetic without mistaking an old example for a current market quote.

Example 1: several items

You give estimates of 60 and 40, for a total of 100. You receive estimates of 75 and 50, for a total of 125. The difference is 125 − 100 = +25, which is +25% of the 100 you give. The result is numerically higher, without proving demand or acceptance.

Example 2: equal totals

You give 60 + 40 and receive 100. Both totals are 100, so the numerical result is Fair. There is no need to label a zero difference as “Winning”. Item type, source quality and actual eligibility still require a separate check.

Example 3: an unknown permanent quote

You select a physical fruit with a quoted estimate and a permanent fruit whose source quote is missing. The tool shows an incomplete offer. It cannot treat the permanent item as zero or copy the physical number. Select Permanent fruit and enter a separately supported estimate.

Why reversing a trade changes the percentage

The formula uses what you give as the denominator: (Wants − Has) ÷ Has × 100. Reversing 100 for 125 gives (100 − 125) ÷ 125 = −20%. That is consistent with the original +25%, because the denominator changed.

Try the examples

  1. Open the calculator workspace and add the appropriate item types.
  2. Replace the initial estimates with the example numbers. The tool permits up to four selected items per side.
  3. Read the totals and difference. Clear a required field to observe the incomplete state, then fill it again.
  4. Use Remove or Clear both offers to start a new example.

The source table contains dated publisher estimates. These worked examples are original arithmetic exercises, not recorded successful trades or accuracy tests.
