Net Present Value (NPV) Calculator

The Net Present Value (NPV) Calculator substitutes your inputs (Initial investment, Annual cash flow, Discount rate, Years) into the standard expression: NPV = -Initial investment + Annual cash flow × (1 − (1 + Discount rate ÷ 100)^(-Years)) ÷ (Discount rate ÷ 100). Every variable is read straight from the fields on this page, and the result is computed the moment you enter the values.

1. 1

   Step 1

   Provide the financial figures you have and start the calculation.

2. 2

   Step 2

   Click the "Calculate" button to see the result instantly.

3. 3

   Step 3

   You can re-run the calculation with different values anytime.

4. 4

   Step 4

   The breakdown lists your inputs — Initial investment, Annual cash flow next to the value computed by NPV = -Initial investment + Annual cash flow × (1 − (1 + Discount rate ÷ 100)^(-Years)) ÷ (Discount rate ÷ 100); read it before relying on the number.

   Step 5

   Adjust one input at a time and compare scenarios: change Initial investment and re-run to see which variable moves the net present value (npv) result most.

• 1

  The Net Present Value (NPV) Calculator needs every variable in consistent units — Initial investment, Annual cash flow — before the standard formula returns a valid result, so check each field's unit before entering values copied from elsewhere.

• 2

  Enter values in the units the Net Present Value (NPV) fields expect — Initial investment, Annual cash flow and the rest; mismatched units are the most common way a correct formula yields a wrong number no calculator can detect.

• 3

  Round only at the end: Net Present Value (NPV) carries full precision internally, so rounding intermediate values by hand can shift the final answer more than the accuracy of the formula itself ever would.

• Swapping Initial investment with Annual cash flow computes a different quantity. If the Net Present Value (NPV) result looks implausible, check the labels first: each value must sit in the field its label names.

• Initial investment and Annual cash flow must be entered in one consistent unit system: months against years skews the Net Present Value (NPV) result silently. Convert every input to the unit named on its field first.
