What does a negative required cash flow mean?

Discounted terminal proceeds exceed the initial outlay. The model can therefore tolerate an annual net outflow while still reaching zero NPV; scrutinize that terminal estimate.

Does the tool work with a zero discount rate?

Yes. The annual discount factor equals the number of years, so investment less terminal value is spread evenly across the project life.

Should disposal costs be positive or negative?

Enter terminal proceeds less disposal costs. A net disposal obligation is negative and increases the required annual cash flow.

Can I enter changing annual savings?

No. This threshold assumes equal annual net cash flows. Evaluate uneven yearly flows separately rather than replacing them with an undiscounted average.

Break-Even Project Cash Flow Calculator

Calculate the annual net cash flow needed for zero project NPV. Enter the initial investment, annual discount rate, whole project life and signed terminal cash value.

What this calculator does

Find the equal annual net cash flow that makes a project break even at your discount rate.

Formula used

Annual discount factor = sum of (1 + annual rate / 100)^(-year), year 1 through project life
Terminal present value = terminal cash value × (1 + annual rate / 100)^(-project life)
Required annual cash flow = (initial investment − terminal present value) / annual discount factor
At zero discount rate, annual discount factor = project life

Inputs explained

Initial Investment: Use the total cash outlay at the project start.
Annual Discount Rate: Use the approved annual rate matching the cash-flow valuation basis.
Project Life: Use the whole number of annual end-of-year cash flows.
End-Of-Life Net Cash Value: Use final sale proceeds less disposal and other terminal cash costs.

How to use the result

Best suited to equipment investment savings threshold, capital approval Break-Even target.
Supported project life is one to fifty whole years. Uneven flows, taxes, financing and working-capital changes need a fuller cash-flow model unless already included.

Current U.S. benchmarks

As of 2026-10-02, the U.S. prime lending rate is 7.00% (Federal Reserve via FRED). Equipment loans and lines of credit typically price at prime plus a spread, so use your actual borrowing rate when you have it.
