Quick FAQ

Is this financial advice?
No. Payback period is a simple recovery-time metric and ignores many investment risks.

Can it handle irregular cash flows?
Use the tool fields shown. If only a fixed annual cash flow is supported, irregular cash flows need a separate schedule.

Does payback include time value of money?
Simple payback does not. Discounted payback uses a discount rate, but still ignores cash flows after payback.

When is payback useful?
It is useful for liquidity and risk screening, but should usually be compared with NPV, IRR, and strategic factors.
