Unrecovered Amount at Maximum Period ₹0

Enter the investment and annual cash flow to calculate the estimated payback period.

Note: This is a simple payback estimate. It ignores the time value of money, taxes, financing costs and changes in cash flow unless included in your inputs.

How this Payback Period Calculator works

The simple payback period is calculated by dividing the initial investment by annual net cash flow, where annual net cash flow equals annual cash inflow minus annual cash outflow.

If annual net cash flow is positive, the result is expressed in years and months. If it is zero or negative, the investment does not recover its initial cost.

How to use this calculator

What to enter

Enter or select the following as requested: Currency Display only; Initial Investment; Annual Cash Inflow; Annual Cash Outflow; Maximum Period. Follow the units, valid ranges, examples, and options displayed beside each field.

What the result means

The financial result is a projection based on the contribution or principal, rate of return or interest, fees, tax assumptions, and time period entered. Check compounding frequency, deposit timing, inflation treatment, and whether the rate is nominal or real; actual returns and tax treatment can differ.

When to use it

Use this to compare savings, investment, deposit, or personal-finance scenarios. Treat the result as an estimate rather than a guaranteed return, and verify current product terms, fees, and local tax rules before making a financial decision.
