📈 How compound interest works and why it is needed

This investment calculator shows the magic of compound interest in action. Unlike a regular deposit, where profits are withdrawn, here income is reinvested, creating an avalanche-like capital growth.

Example: If you save 5,000 ₽ per month at 15% per annum, in 10 years you will have accumulated not 600,000 ₽ (as in a money box), but more 1,300,000 ₽. The calculator will help you find your ideal strategy.

What to consider when making calculations?

  • Starting capital:The amount you start with.
  • Term: The longer the term, the stronger the compound interest works (exponential growth begins after 5-7 years).
  • Reinvestment: A checkbox that includes adding the profit received to the main body of the deposit.

💡 Important: Investments bring income, but do not forget that the state withholds tax on profits. You can calculate net profit minus 13% using our personal income tax calculator.


Frequently asked questions (FAQ)

🔹 What is the reinvestment rate?

This is a process where the interest received is not withdrawn to the card, but added to the account. Next month interest is accrued on the increased amount. This is what ensures rapid capital growth.

🔹 How to take inflation into account?

To understand the real purchasing power of a future amount, subtract the inflation rate from your interest rate. For example, if the yield is 15% and inflation is 10%, your real capital growth is 5%.

🔹 Is it possible to calculate losses?

This tool is designed to simulate the growth of assets (stocks, bonds, deposits) and assumes a positive return. Market risks are not taken into account in the basic model.
