With the percentile calculator you will calculate the percentile position and find the value. Percentile or centile is a measure in statistics that indicates a value for which P Percentage of the Population is equal to or less than that value and 100-P is greater.

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.

Calculate the diagonals of a concave deltoid, kite, side lengths, surface area, perimeter and radius of the inscribed circle. Each size can be calculated using many formulas, just indicate what data we have.

Using the calculator, you will calculate the basic metabolic rate (BMR-basal metabolic rate) and the amount of calories needed to supplement, i.e. burned by the body on an empty stomach (in the morning, without a meal), in physical and mental peace.

How far is the storm? How close is lightning? Is the storm looming or is it moving away? Surely everyone has asked themselves such questions. That is why we have created a lightning distance calculator with which you can easily check it.

The caloric demand calculator will help you create the right diet. It will answer the question of what is our daily calorie requirement and how much daily do we need to consume carbohydrates, proteins and fats to gain weight or lose weight by a given weight within a certain period of time.
We have a choice of several of the most popular formulas for calculating the basal metabolic rate. As a result, we will also get a seven-day alternating caloric cycle, thanks to which, with long-term diets, we can "cheat" the body by consuming different caloric values a day while maintaining a weekly diet.

With this calculator you will calculate the weighted arithmetic mean.

With this calculator you can calculate voltage drops for single-phase and three-phase AC circuits calculated from the rated current. You will also calculate wire length, wire diameter, wire cross-sectional area, voltage or current.

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) .

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.

You can calculate any system of linear equations, both homogeneous and heterogeneous with any number of unknowns Using the Inverse of a Matrix method.

With this calculator you can quickly calculate the kinetic energy of an object. You will also calculate mass from energy and velocity and speed given kinetic energy and mass.

With this calculator you can calculate the HB hardness or the hardness of metals based on the Brinell hardness test.

Parallelogram calculator will help you calculate the long diagonal of the parallelogram, the short diagonal of the parallelogram, the side length, heights, area of the parallelogram.

Thanks to the calculator you can calculate the number of letters, the number of words, the number of characters and the number of paragraphs in any text.

Using this calculator, you can calculate the total volume of the solution after dilution and the volume of solvent added during dilution.

With this calculator you can perform a complete product form analysis of the quadratic function with explanations. The calculator will show you how to find the general form of a quadratic function from its product form. Moreover, it will determine the zeros of the function, its vertex coordinates, calculate the delta and present the canonical and general form of our function.

With this calculator you will calculate the geometric mean, also called the power mean of the zero order.

Burrows-Wheeler transform online encoder and decoder. Encrypt and decrypt any cipher created in a Burrows-Wheeler transform.

The life expectancy and health age calculator will let you know your life expectancy. First of all, it will make you aware of what factors affect your life expectancy and your real age according to your health.
