All payment figures, balances, and interest figures are estimates based on the data you provided in the specifications that are not exhaustive despite our best effort.

Successful implementation of the investment plan

In order to create an investment plan, realistic goals and calculations are necessary.

Implementation is another important area of investing. The total cost of buying and selling stocks, ETFs or mutual funds is important. Costs should not exceed 0.5% of your portfolio. Always remember that costs must be subtracted from an average return. You can easily simulate with our Investment Calculator how the final result will change if you reduce the Expected annual rate of return by a few percentage points.

For this reason, you need a broker that offers a professional service and has a low total cost structure.
