Future value of investment (FV) - calculator

The FV calculator helps us calculate the future value of the investment. The FV calculator calculates the amount we will receive in the future after validating a given amount now for a specified number of years and after calculating the interest due, assuming that they will be capitalized (added to the capital) with a given frequency (e.g. weekly, monthly, quarterly, semi-annually, annually) .

Weighted arithmetic mean calculator

Present value of investment (PV) - calculator

The PV calculator helps us to calculate the current value of an investment, i.e. the PV (present value). The PV calculator calculates the amount we need today to obtain the given value in the future after a certain number of years and calculating the interest due, assuming that they will be capitalized (added to the capital) with the specified frequency (e.g. weekly, monthly, quarterly, semi-annually, annually) ie how much do you need today to get X in the future
