About Garage Sale Pricing Calculator

Garage sale pricing starts from a condition-based share of the original price, typically 25% for a good used item, reduced a further 5% per year of age and rounded to a convenient figure. Buyers at a garage sale are looking for a clear bargain, so pricing above about 40% of original almost always ends with the item unsold.

Formulas

Suggested price

price = original price x condition share x (1 - 0.05 x age in years)

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
