How to Sell Calculators for Maximum Profit
The secondary market for graphing and scientific calculators is remarkably robust. Students and professionals alike often look for high-quality used devices like the TI-84 Plus CE or the Casio FX-991EX. To successfully sell calculators, you need to understand the math behind the margins.
Key Metrics Explained
- Acquisition Cost: This is what you pay to acquire the inventory, including the base price and any shipping or gas money spent picking up the items.
- Marketplace Fees: Platforms like eBay, Amazon, or Mercari typically charge between 10% and 15% of the final sale price. Always account for this before setting your price.
- Net Margin: This is the percentage of the total sale price that remains as profit after all expenses are paid. A healthy margin for electronics flipping is usually between 15% and 30%.
Example Calculation
Imagine you buy a lot of 10 graphing calculators for $400 ($40 each). You spend $20 on shipping them to you. Your total cost per unit is $42. If you want a 25% profit margin and the marketplace takes a 13% fee, you cannot simply add 25% to $42. You must use the formula: Price = Cost / (1 - Fees - Margin).
In this case: $42 / (1 – 0.13 – 0.25) = $42 / 0.62 = $67.74 per unit.
Tips for Scaling Your Calculator Business
To maximize your return, consider selling during "Back to School" season (August-September) when demand is highest. Always test every button and the screen for dead pixels, as functional "Grade A" calculators fetch a significant premium over those with cosmetic wear.
