How to estimate the total cost of upgrading a Telegram gift
An upgrade costs the gift's original price plus Telegram's upgrade fee, both in Stars. The calculator adds them and converts the total to USD and TON.
Telegram gift upgrade cost formula
The original gift price and the upgrade fee are added in Stars. That total is multiplied by the USD price of one Star ($0.013 by default), then divided by the TON price from CoinGecko.
Total Stars = original gift price + upgrade fee. Estimated TON = total Stars × USD per Star ÷ USD per TON.
Original cost is not current market value
The catalog price is what the gift cost in Telegram. The collection floor is the cheapest listing in the collection, and it can belong to any model, backdrop or number.
A floor above your cost describes the cheapest listing. Your upgraded gift can sell for more or less.
What to check before upgrading
- Confirm the exact upgrade fee shown for your gift inside Telegram.
- If you bought Stars, enter what you paid per Star.
- Check current listings for the collection and relevant models.
- Add the marketplace fee you will pay when you sell.
Why the model matters
An upgrade turns the gift into a collectible with its own model, backdrop and symbol. These attributes affect its price, so one collection can have listings far above its floor.
How to read the comparison
TON puts your Stars cost and the market floor in one unit. The difference shows how far the cheapest listing is from what you pay to upgrade. It compares today's prices; the attributes you get and the price a buyer pays decide the actual result.
