There is no direct formula to calculate IRR instead what we have is an equation that states IRR is the rate at which NPV is zero. NPV or Net Present Value is the difference between compounded net cash flows discounted at IRR and the initial expense
What we resort to instead is hit and trial method, where we start off with an initial guess and find the NPV. If the NPV comes out positive we take a second guess to bring NPV below zero. Once we have two opposing NPV values, we use linear interpolation to find the approximate IRR value
Here is an example say we were investing $100,000 and expecting four cash inflows at the end of each of the next four years in amount of $30,000 each
Here are the NPV Calculation from an online NPV tool found in the related link

∙ 13y agoIf you know the net cash flows, such as initial cost of the project and expected benefits, you can then find IRR with paper and pencil as listed below . You will need to arrive at two different NPV values one which is positive and the other which is negative. Once we have two rates at which the NPV values are at opposing ends we can use linear interpolation to find IRR
These calculations below are from an online irr calculation tool listed in the related link section

∙ 13y agoIRR Definition
IRR which stands for Internal Rate of Return is the investor's required rate of return for an investment proposal. IRR sets equal the initial cash out lay or investment expense to the present value of net cash flows. At the internal rate of return the net present value of investment is zero.
Acceptance Criteria
If the internal rate of return is higher than the discount rate or the cost of capital then the investment should be made. But if IRR lies below the cost of capital that will drive the net present value to be negative thus there won't be any benefits in making the investment
Disadvantages of IRR
- IRR may not be unique as we might get multiple IRR values this is due to the face that IRR equation is a polynomial thus having multiple roots or solutions.
- IRR may not exist in certain situations
- Making a decision solely based on IRR is not wise as the investment may have smaller NPV or larger payback period as compared to other investments under consideration

Why is the IRR not the MIRR the industry standard rate of return?
The IRR assumes all cash flows are reinvested at the IRR. All you need are the property cash flows and the initial outlay to solve the equation. So, it is a simple and objective calculation. For reference, the calculation is as follows: NPV = 0 = CF0/(1+IRR)^0 + CF1/(1+IRR)^1 + ... + CFn/(1+IRR)^n The MIRR assumes that positive cash flows are reinvested at a reinvestment rate. MIRR also assumes that negative cash flows are financed by the company at a finance rate. For reference the calculation is as follows: (( NPV of positive cash flows at reinvestment rate ) / ( NPV of negative cash flows at finance rate ))^(1/(n-1) - 1 This makes MIRR unsuitable as an industry standard. First, different firms have different reinvestment rates and different finance rates. So, MIRR cannot be used to compare investments purchased or sold by different companies. Second, the rates will change over time, thus making it impossible to compare MIRR's at different intervals. MIRR is best used internally by a particular firm choosing between several investments at a given time.

What is the difference between IRR and yield to maturity?
IRR (Internal Rate of Return) is a metric used in corporate finance to assess the relative value of projects. YTM (Yield to Maturity) is a metric used in bond analysis to determine the relative value of bond investments. Both are calculated the same way, by assuming that cash flows from the project/bond are consumed.
What is IRR reinvestment rate assumption?
The IRR reinvestment rate assumption is the mistaken assumption that the IRR of a project implicitly assumes that all positive cash flows from the project that occur in periods before the end of the project will be reinvested at the rate of IRR per period until the end of the project.
What is the effect on IRR if cost of capital decreased?
A change in the cost of capital will not, typically, impact on the IRR. IRR is measure of the annualised effective interest rate, or discount rate, required for the net present values of a stream of cash flows to equal zero. The IRR will not be affected by the cost of capital; instead you should compare the IRR to the cost of capital when making investment decisions. If the IRR is higher than the cost of capital the project/investment should be viable (i.e. should have a positive net present value - NPV). If the IRR is lower than the cost of capital it should not be undertaken. So, whilst a higher cost of capital will not change the IRR it will lead to fewer investment decisions being acceptable when using IRR as the method of assessing those investment decisions.
Why is the NPV approach often regarded to be superior to the IRR method?
Why is the NPV approach often regarded to be superior to the IRR method?
IRR VS NPV?
IRR: Internal rate return NPV: Net present value Both are measure of the viability of a project(s) You can have multiple IRR (because of discontinued cash flows) but you always have one NPV.
