With this calculator you will calculate the harmonic mean.

The calculator is used to calculate the coverage of bills by profit before paying off the tax bill.

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

Thanks to the calculator, you can easily calculate the amount of calories you burn every day. There are over 600 different activities available, from which you can choose those that were or will be performed on a given day and set the duration for each selected activity.

As a result, the calculator will provide the total duration of all activities, the sum of calories burned and the number of calories consumed for each activity separately, including the time of its execution. The calculator also tells you how many hours you need to constantly perform a given activity to lose weight by about 0.5 kg, taking into account your weight.

This calculator helps us check whether the planned investment will be profitable and whether the project should be accepted or rejected.
Thanks to the calculator, we can calculate:
NPV (Net Present Value) - sum of discounted net cash flows
PI (Profitability Index) - investment profitability
IRR (Internal Rate of Return) - internal rate of return
DPP (Discounted Payback Period) - discounted payback period
Value of discounted net cash flow for each period.

Thanks to the WACC calculator, we will calculate the average relative cost of capital employed in financing investments by the enterprise.
The weighted average cost of capital takes into account the diversification of the investment financing structure and the various costs of individual capital components, and indicates the average relative cost of the enterprise engaging a given capital.

The CAPM calculator can be used to calculate the cost of equity, to evaluate the investment effectiveness of collective investment funds (open-end investment funds, pension funds, etc.), to study the efficiency of the stock market, etc.
The CAPM calculator in the form of SML allows you to calculate the expected rate of return on all portfolios, not only effective ones, as well as individual stock market shares.
