# What does the upgrade really cost?

Pick what you have and what you want. We price the new one and estimate what yours sells for after fees.

 Net cost of the upgrade

 New one, cheapest today

 You keep from selling yours

What you have

What you want

 Your sale price ($)
 Your shipping cost to the buyer ($)
 New one's price ($)

## How it works

The sale price starts at the 25th percentile of today's eBay asking prices for your item: priced to sell, not the hopeful top of the market. We take off eBay's final value fee (13.6% plus $0.40 for most categories, charged on the sale price) and the shipping you pay. The new price is the cheapest current listing. Change any number to match your own offer.

Check whether an offer on the new one is any good with the [price checker](https://sharpest.ai/tools/price-check), or size the power supply for a new card with the [PSU calculator](https://sharpest.ai/tools/psu-calculator).
