A teacher said:
Tax-exempt account:
假设本金$1, 放进Tax-exempt账户只需要每次contributions的时候交15%税,取出的时候不需要额外交税,所以在15年后,当你取出的时候,你手上的金额应该为1*(1-15%)*(1+r)^n。
如果不用交税你应该获得1*(1+r)^n,所以tax drag是1*(1+r)^n*(15%)。
But, why don't we use [1*(1-15%)*(1+r)] ^ n? We paid tax at the beginning, not when we withdrew n years later.
