如何估算转让费？

现在在协议005中,我们必须为每个tz1 -> tz1 转让费用.此外,如果这是地址中的第一笔交易,我们还必须添加另一个1420互斥锁以显示.我过去经常通过发送一笔金额等于余额减去1420或2840互斥量的交易来清空我的帐户.

所以

 total_fee = tx_fee + reveal_fee(if needed)
amount = balance - total_fee
 

这个计算公式对我来说很好.但是刚才我遇到一个错误,说"余额不足".我看到所需的平衡与实际之间的差异是1420静音.但是我已经从余额中减去了2480个互斥量.

我还应该在公式中算哪种操作?

Now in Protocol 005 we have to pay estimated 1420 mutez for each tz1 -> tz1 transfer in fees. Also if it's the first transaction from the address we have to add another 1420 mutez for reveal. I used to empty my accounts by sending a transaction with an amount equal to the balance minus 1420 or 2840 mutez.

So,

total_fee = tx_fee + reveal_fee(if needed)
amount = balance - total_fee

This calculation formula worked for me fine. But just now I've faced an error says "not enough balance". I see that the difference between needed balance and actual is 1420 mutez. But I've already subtracted 2480 mutez from the balance.

Which kind of operation should I also count in the formula?
