There's a charge of 220 yen to get a refund on your Suica card's remaining balance. However, you'll also receive the 500 yen deposit you paid when first purchasing your Suica. If the remaining balance on your card is less than 220 yen, you will only receive your deposit of 500 yen.
This is how the amount is calculated below:
Remaining Balance - Commission Fee (220 yen) + Deposit (500 yen) = Refundable Amount
