Calculating the cash adjustment

The basic calculation is simple: compare the agreed values of the two items and assign the difference to the party receiving the higher-value item.

The difficult part is not the subtraction but which values to use.

If one item is valued at a realistic selling price and the other at the highest asking price found online, the cash adjustment is biased from the start.

Before agreeing the final amount, agree on the method: realistic market value, trade value or another explicit reference.

After comparing the models, adjust the valuation for the specific units involved.

Consider:

• cosmetic condition;
• functional condition;
• repairs;
• modifications;
• original parts;
• accessories;
• case;
• documentation;
• missing items.

The cash adjustment should reflect the actual items being traded, not two ideal examples taken from a price list.

A valuation does not necessarily produce one indisputable number.

You may conclude, for example, that a reasonable difference falls within a range.

At that point, other factors can matter:

• personal interest;
• urgency;
• convenience of the trade;
• avoided costs;
• ease of sale;
• model availability.

The final cash adjustment can therefore be negotiated, provided both parties understand the values being used.

Some negotiations develop like this:

“Mine is worth 1,200 instead of 1,000, so yours can be worth 900 instead of 750.”

The result may appear balanced, but it makes the real difference harder to understand.

It is clearer to keep both values close to realistic references and negotiate the difference directly.

Higher nominal figures do not improve the trade: what matters is the relationship between the two values and the real convenience for both parties.
