Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Future net inflows must already be discounted at the chosen rate. Later outflows must be included consistently.
Example Calculation
- Present value of future net inflows: 1200
- Initial investment: 1000
Present value of future net inflows = 1200; Initial investment = 1000. The primary result is 1.2.
Frequently asked questions
How do I use this calculator?
Enter present value of future net inflows, initial investment. The result updates automatically. Use Reset to restore the example values.
What method does it use?
PI=PV future inflows/initial investment.. Future net inflows must already be discounted at the chosen rate. Later outflows must be included consistently.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
