Use boundary

Calculation path

A bounded solver searches from -99.99% to 1,000% for a discount rate that makes the present value of all five annual flows equal the time-zero investment.

Calculation path

IRR solves 0 = -initial investment + sum of cash flow in year t / (1 + IRR)^t.

What you provide

Initial investment: Cash paid at time zero before any annual inflows.
Year 1 cash flow: Net cash flow received at the end of year 1; enter a negative amount for an additional outflow.
Year 2 cash flow: Net cash flow received at the end of year 2; enter a negative amount for an additional outflow.
Year 3 cash flow: Net cash flow received at the end of year 3; enter a negative amount for an additional outflow.
Year 4 cash flow: Net cash flow received at the end of year 4; enter a negative amount for an additional outflow.
Year 5 cash flow: Net cash flow received at the end of year 5; enter a negative amount for an additional outflow.

What you receive

Estimated annual IRR
Total undiscounted inflows and net gain
NPV check at the solved rate

Choose the maximum decimal places shown. This does not increase source accuracy.

IRR can have multiple solutions when cash-flow signs change repeatedly and can rank differently sized projects poorly.
