Understanding payback & ROI
Payback period
The time until cumulative cash flow covers the initial investment. Faster payback generally means lower risk. The calculator interpolates if payback falls mid-period.
Simple ROI
Return on Investment = (total cash flow − investment) ÷ investment × 100%. It gives a rough overall return, without accounting for timing.
Method limits
Payback and simple ROI ignore the time value of money. For large investment decisions, complement with NPV and IRR analysis.
FAQ
Frequently asked questions
How do I calculate the payback period?
Accumulate net cash flow each period until it covers the initial investment. E.g. Rp100M with Rp30M/year → payback about 3.3 years. The calculator computes it automatically, including varying yearly flows.
What's a good payback period?
It depends on the business and its risk. Generally, faster is better. Compare with your expectations and alternatives; higher-risk ventures usually demand faster payback.
What is ROI and how is it computed?
ROI = (total cash flow over the period − investment) ÷ investment × 100%. E.g. total flow Rp150M on Rp100M → ROI 50%. It's a rough return, not time-adjusted.
Why isn't payback enough for big decisions?
Because it ignores the time value of money and cash flows after payback. For large or long-term projects, also use NPV and IRR for a more accurate decision.
Can it handle different cash flow each year?
Yes. Choose 'different each year' mode and enter each year's cash flow. The calculator finds when the cumulative covers the investment, including interpolation in the final year.
