Here you can calculate your savings in a savings account. Enter how much you want to save each month, the calculated savings rate and your target amount.
The interest in the calculation is accumulated once a year, and the tax is deducted at the same time. Some banks instead pay out the interest on the savings account every month or every quarter. The difference is very small.
There are several niche banks that offer high interest on savings accounts, and the usual big banks are usually among the worst when it comes to savings. You can usually also tie up the money in a savings account for a period of time to get a higher interest rate.
