现在只要说到现货白银，很多人都会想到外盘的伦敦银产品，同时会想到的就是这个产品门槛很低，交易成本很低，但收益很高，这是怎么算的呢？今天，小编就来简单说说这个问题。
现货白银交易费计算
在现货白银的交易中，会成为交易成本一部分的包括点差和仓息，其中仓息是持仓超过一个交易日才会收取的，在同一交易日内完成建仓平仓的是不会收取这个费用的。
下面以交易一手伦敦金为例来说明。
| 基础假设 | 建仓价格 | 交易方向 | 平仓价格 |
| 14.80 | 做空 | 14.00 | |
| 当日平仓 | 交易费=点差*手数*合约单位=0.03*1*2500=75美元 | ||
| 隔夜平仓 | 交易费=点差*手数*合约单位+仓息
仓息=入市价*过夜天数*手数*合约单位*利息/360 =14.80*1*1*2500*0.25%/360 =0.26 交易费用=75+0.26=75.26美元 |
||
| 持仓5天后平仓 | 交易费=点差*手数*合约单位+仓息
仓息=入市价*过夜天数*手数*合约单位*利息/360 =14.80*4*1*2500*0.25%/360 =1.03 交易费用=75+1.03=76.03美元 |
||
| 备注：平台点差0.03美元/盎司；合约单位为2500盎司；过夜利率：买入-1.75% 卖出-0.25% | |||
现货白银交易所需资金量
既然伦敦银被称为门槛最低的投资产品，那么其交易所需要的资金量到底需要多少呢？大田环球的伦敦银标准合约中，交易保证金为每手1000美元，即若伦敦金的价格为14.50美元，交易一个标准手（2500盎司），理应需要14.50*2500=36250美元的资金量的通过保证金机制则只需要1000美元。
通过上述计算，大家是不是对市场上所述的伦敦银投资门槛低、交易成本低、收益高有更深一层的了解了呢？
