How to use the calculator
- Enter the price shown for one package.
- Enter how many packages you plan to purchase.
- Add a real voucher or promotion percentage, not an unconfirmed advertisement.
- Add any service or wallet percentage fee.
- Add a fixed payment charge when the checkout uses one.
- Compare the calculated total with the final payment screen before approving the transaction.
What the calculator does not include automatically
Regional tax, card conversion, wallet exchange rates, platform-specific pricing, first-purchase bonuses, and voucher eligibility can change. Enter known fees manually and treat the payment provider’s final confirmation screen as the authoritative amount.
Account safety: A top-up calculator never needs a password, OTP, recovery code, card number, wallet PIN, or remote access to your device.
