IRR Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans
What Is a IRR Calculator?
An Internal Rate of Return (IRR) calculator is a financial tool used to calculate the profitability of an investment over a certain period of time. In South Africa, this calculator is essential for investors, business owners, and individuals looking to make informed financial decisions. For example, it can be used to determine the return on investment for a property purchase, business expansion, or retirement savings.
How to Calculate IRR Manually
The formula to calculate IRR manually is a bit complex, but basically, it involves finding the discount rate that makes the net present value (NPV) of all cash flows from an investment equal to zero. This rate is considered the internal rate of return. The formula is:
IRR = C0 + (NPV / PV) * 100
Where:
- C0 is the initial investment
- NPV is the net present value of cash flows
- PV is the present value of cash flows
For a worked example using South African values, consider a business investment of R100,000 with expected cash flows of R30,000 in year 1, R40,000 in year 2, and R50,000 in year 3. Calculate the IRR for this investment.
