Internal Rate of Return calculator
Instructions
- This calculator allows to represent and calculate a financial scenario with a current value, a rate of return, and as many single payments and periodic payments as desired
- Use the radio buttons to select which variable you need to calculate
- Enter the values for the other variables, and press ENTER (or "calculate" button) for the target to be calculated
- Press "add" under "Single Payment" and "Periodic Payment" to add more payments to the scenario
- Press "reset" if you need to restore the calculator to its initial state. Refreshing the page might work just as well
- Notice that in some cases (no possible solutions, or some programming mishap) the calculation might fail. Please be gentle and check your input data.
- Notice that in some cases there might be multiple solutions (e.g. the IRR if there are strong negative cash flows at some point). You can enter a target value estimate (or any value) so it is used as a start value for the approximation algorithm.
- Notice that your data is not saved, and there might be incompatible scenarios. You might be using an spreadsheet as well.
- Although this is tested to some extent. There is no guarantee that the results are accurate. USE AT YOUR OWN RISK.

Regarding this work I would like to thank the following:
- Banco de España employed me for developing a mortgage calculator. The source code is independent, but the problem is similar.
- I learned some Financial Maths with prof.Javier Miner (Deusto), who was an awesome teacher.
- I learned some Computer Calculus with prof.Simeón Gutiérrez, which I did not enjoy so much.
- I learned some stuff like Web design from Raúl Calvo, and other co-workers whose names I hardly can remember.
- I would also like to thank all the software community who have contributed to open technologies and tools which have made this work feasible.
- And thanks dad for all these years of unconditional support.
