$2.20 assumed Steam buyer price per key; approximately $1.92 net. This is not a live Steam price.

Before additional costs (unknown)
Estimate only: no guaranteed savings or immediate resale. Check Steam market eligibility, item marketability, currency, taxes and final fees. Leftover wallet credit is not a cash refund. TF2 keys are inventory items, not game activation keys.
Published fee rates
Steam Support currently lists a 5% Steam transaction fee with a $0.01 minimum and a 10% Team Fortress 2 game fee. The buyer pays the fees; the calculator estimates the seller proceeds represented by a buyer-facing market price.
Formula
For each key, the estimate searches cent values for the highest seller proceeds whose proceeds plus the estimated Steam and TF2 fees do not exceed the buyer price. Each result is then multiplied by the key count.
Limits and updates
The fixed $2.20 buyer price is an assumption, not a market average or live quote. It gives approximately $1.92 net under this USD model. Add your conversion and sending costs; a blank cost is unknown. Steam controls final fees, currency rounding, taxes and market eligibility. Check its confirmation screen before selling.
