FAQ

How is the 15.4% income tax calculated?

Income tax = 14% + 1.4% local tax = 15.4% on interest earned. After-tax amount = total deposits + pre-tax interest − (pre-tax interest × 15.4%).

How do I calculate tax-exempt savings?

Tax-exempt accounts pay no income tax on interest. The pre-tax interest shown equals the actual interest received on a tax-exempt account.

How is savings interest calculated?

Each monthly deposit earns interest from deposit date to maturity. The formula is M × r × n(n+1)/2, where the first month's deposit earns the most interest.
