I shared the math for my situation, you need to do the math for your own situation.
Start with the cost of USD->USDT or even another coin you choose. Let's call this amount W.
Then the costs for transferring to another exchange. The exchange should be able to convert from USDT to your local currency.* Call this amount X.
Then the exchange withdrawal costs. Call this amount Y.
Finally the local bank fees for deposit, if any. call this amount Z.
W+X+Y+Z= your total transfer costs.
*If you cannot find an exchange that allows selling crypto for your local currency then you will need to sell it for another currency. Then withdrawal that currency to your local bank account. That bank will charge fees for conversion so you will need to factor that in if applicable.
