Mastercard and online casinos: how much a transaction really costs
In terms of authorisation, Mastercard behaves exactly like Visa: the issuing bank sees the gambling merchant category code and decides whether to let the transaction through. There is no point in going over the mechanics of declines a second time. It is more useful to cover what almost nobody writes about — what the transaction itself costs when it does go through, and why the type of card matters more here than the payment system.

Legal context in brief
Online casinos in Ukraine are legal under a PlayCity licence, and settlements with players are made in hryvnia only, through bank accounts. One specific rule affects your payment directly: gambling transactions funded with credit have been blocked by banks following the National Security and Defence Council decision. So the question of “debit or credit” here is not about discipline, it is about whether the payment will go through at all.
The anatomy of cost: four layers
The amount that leaves your account and the amount on your gaming balance do not always match. The difference is made up of the following elements.
1. The bank’s fee for the transaction
Some banks price transactions with a gambling code separately or limit how many you can make. You need to check this in your own bank’s tariffs, not in reviews: policies differ between institutions and change over time.
2. Conversion, if the card is in foreign currency
For a hryvnia card this layer does not exist at all — legal casinos keep accounts in hryvnia. But if you pay with a dollar or euro card, the bank converts the amount at its own rate, and on withdrawal it will do so again in the opposite direction. The two gaps between the buy and sell rates are your hidden fee.
3. Withdrawal fee
Some sites make one or two requests per month free and charge for the rest. This point lives in the cashier section and is usually discovered only after a win — which is why it is worth reading before your first deposit.
4. Tax on winnings
The largest layer, and it is not a fee: 23% is withheld from every payout — 18% personal income tax and 5% military levy. A legal operator does this itself as a tax agent, so you do not file a declaration. But you do need to calculate your result with this adjustment in mind.
Indicative transaction parameters
| Parameter | Deposit | Withdrawal |
|---|---|---|
| Minimum amount | usually from UAH 100 | usually higher than for a deposit |
| Processing by the operator | instant | from a few minutes to 24 hours |
| Banking cycle | immediate | 1–3 banking days |
| Site fee | usually 0% | 0–3% |
| Tax | — | 23% withheld by the operator |
Debit or credit: the key question
The payment system has nothing to do with it here, yet the difference is fundamental. Paying for gambling with a credit limit, a credit card or an instalment product means playing on borrowed money: the amount you lose turns into a debt to the bank, and the problem does not end with the session, it stretches out over months.
In Ukraine this question has been settled at the system level: such transactions are blocked. But the trap remains elsewhere — in your banking app the credit limit sits right next to your own money and is shown in a similar line. People genuinely do not understand why “the money is there, but the payment fails”. So the working rule is simple: use a separate debit card with your own balance and a small amount for your entertainment budget, and never link credit products to a gaming account at all.
And separately: taking out a loan or an instalment plan to win your money back is the fastest route from a one-off loss to a debt burden. If that thought has appeared, it is already a signal to stop, not to look for a payment method.
What to do about typical failures
Payment declined
First check whether a credit card is linked in the app and whether online payments are enabled. Repeated retries make anti-fraud systems more likely to trigger and can lead to online payments being temporarily blocked.
Money was debited but not credited
This is usually a stuck authorisation: the amount is frozen but not settled, and it is returned automatically within a few days. Contacting support with the date, time, amount and the last four digits of the card speeds up the review. Do not make a repeat payment.
A withdrawal is taking longer than the stated period
First check whether the withdrawal details match the card used for the deposit and whether there is an active bonus with an unmet wager — these two reasons account for most delays. Only then does it make sense to file a complaint.
Responsible gaming
A card makes spending instant and imperceptible — that is its main risk. Set a monthly budget in advance and treat it as spending on entertainment, not as an investment: the mathematical house edge is built into the rules of every game. Do not chase losses, do not play when tired or stressed, and set spending and time limits honestly — with a legal operator this is a mandatory step before your first bet. If you lose control, submit a self-restriction request and consult a specialist. Participation in gambling can cause gambling addiction. Follow the rules (principles) of responsible gaming. 21+.
Frequently asked questions
Does the bank charge a fee for depositing at a casino?
Some banks price transactions with a gambling code separately or limit how many you can make. The exact terms are set out in your bank’s tariffs.
Why does a payment from a credit card fail?
Gambling transactions funded with credit are blocked by banks. This applies to credit cards, to a credit limit on a debit card, and to instalment products.
Is there a difference between Visa and Mastercard for a player?
Practically none: the decision is made by the issuing bank based on the category code. It matters far more whether the card is debit or credit and what tariffs you have.
Why is the withdrawn amount smaller than the balance I had?
23% tax is withheld from the payout — 18% personal income tax and 5% military levy. A site withdrawal fee may also apply.
Does the same-payment-method return rule apply?
Yes. Money is returned to the card the deposit came from. If the card has been reissued, the new one must be added to your profile and confirmed.
