Every Steam account accumulates junk: spare backgrounds, emoticons you'll never use, cards from games you don't care about. Steam lets you grind all of it into gems, and gems buy booster packs.
It looks like free XP. Run the numbers and it mostly isn't — but there's a narrow case where it genuinely is.
Can you level up Steam with gems?
Indirectly, and inefficiently. Gems buy booster packs, each containing three random cards from one game. A pack costs 6,000 ÷ the set's card count — so 400 to 1,200 gems — and you're limited to one pack per game per day. Buying the completed set outright is usually cheaper and always faster.
How gems work
Any tradeable card, background or emoticon can be turned into gems from your inventory. The yield depends on the item — junk backgrounds give little, rarer items give more.
Gems then buy booster packs. The formula is fixed and worth knowing:
Booster pack cost = 6,000 ÷ number of cards in the set
So a 5-card set's pack costs 1,200 gems; a 15-card set's pack costs 400. The range is always 400–1,200 gems.
Gems also bundle into a Sack of 1,000 Gems, which is tradeable and sells on the Market. That's what gives gems a real exchange rate.
What a booster pack is actually worth
Here's where it gets uncomfortable.
A Sack of 1,000 Gems sells on the Market for roughly $0.45–0.55, and after Steam's ~15% fee the seller nets about $0.38–0.47. Call it $0.40 per 1,000 gems.
Now price a typical booster pack. The median set has 6–7 cards, so a pack costs around 900–1,000 gems — about $0.40.
For that you receive three random cards out of a set that needs six or more, with duplicates entirely possible.
Compare against simply buying the finished article:
| Cost | What you get | |
|---|---|---|
| One booster pack (~1,000 gems) | ~$0.40 | 3 random cards, duplicates possible |
| The median complete set | $0.73 | Every card, guaranteed, craftable now |
Two packs cost roughly $0.80 and still might not complete a six-card set. The set itself costs $0.73 and always does.
Buying sets beats buying booster packs, on both price and certainty.
The one case where gems win
If the gems came from items you were never going to sell.
A background worth $0.03 is barely worth listing — the Market fee eats it, and it may sit unsold for weeks. Grinding a pile of that into gems converts genuinely dead inventory into something usable. In that scenario your gems cost you nothing real, and a booster pack is free XP progress.
The distinction is simple:
- Gems you'd otherwise never realise value from → spend them, it's free
- Gems you could sell as a Sack for $0.40 → sell them and buy sets instead
Most people's gem piles are the first kind. Most people's plans assume the second.
The daily limit kills it as a strategy
Even ignoring the economics: you can buy one booster pack per game per day.
Reaching level 100 needs 550 complete sets. At three random cards per pack, one pack per game per day, you'd be at this for years — and you'd still need the duplicates to fall correctly.
Booster packs are a trickle. They are not a route to a target level.
Free booster packs and your Steam level
Steam also grants booster packs at random to players who own a game, and this is where level genuinely helps: the odds improve by roughly +20% for every 10 levels.
Read that carefully. It's a relative increase applied to a very small base chance. Going from level 10 to level 50 takes you from +20% to +100% — a doubling of something that was tiny to begin with. Valve also runs an anti-bad-luck adjustment, improving your odds the longer you go without a pack.
It's a pleasant side effect of levelling. It is not a reason to level, and any site presenting it as one is inflating it.
What to actually do with gems
- Grind genuinely worthless items — junk backgrounds and emoticons under a few cents — into gems.
- Spend those gems on booster packs for games whose sets you're already collecting, so duplicates still help.
- Sell gems as Sacks if you have thousands, and put the funds toward complete sets instead.
- Never buy gems with the intention of levelling. You're paying a premium for randomness.
And if you're paying with gems rather than converting them, note that we accept Steam Gems directly as a payment method — which skips the conversion loss entirely and buys guaranteed complete sets rather than three random cards.

Frequently asked questions
How many gems does a booster pack cost?
6,000 divided by the number of cards in that game's set, so between 400 and 1,200 gems. A five-card set costs 1,200 gems per pack; a fifteen-card set costs 400. You can buy one pack per game per day.
Is it cheaper to buy booster packs or card sets?
Card sets. A typical booster pack costs around 1,000 gems (roughly $0.40) for three random cards, while the median complete set costs about $0.73 and is guaranteed craftable. Two packs cost more than a set and may still leave it incomplete.
Does Steam level increase booster pack drops?
Yes, by roughly +20% for every 10 levels — but it is a relative increase on a very small base chance, so the practical effect is modest. Valve also improves your odds the longer you go without receiving one.
What are Steam gems used for?
Turning unwanted cards, backgrounds and emoticons into a crafting currency that buys booster packs. Gems can also be bundled into tradeable Sacks of 1,000 and sold on the Market, or used directly as payment on some trading sites.
