CapEx Calculator (Capital Expenditure)

Capital Expenditure (CapEx) is money spent to acquire, upgrade, or maintain long-term physical assets such as machinery, vehicles, buildings, or software. Unlike day-to-day operating expenses, CapEx creates value over many years — so the key question is whether that future value justifies the upfront cost.

This calculator lets you build a dynamic list of CapEx items, choose a financing mix (equity vs debt), model the operating benefits and costs, and then evaluate the investment through payback period, break-even analysis, NPV, ROI, and a resale price simulation.

How Payback Period works

The payback period tells you how long it takes for the asset to recover its cost from the cash it generates. The unlevered payback ignores financing and divides total CapEx by net operating cash flow. The equity (levered) payback accounts for the loan payment and shows how fast your own capital is returned.

How the resale / break-even simulation works

If you plan to sell the asset at a certain year, this calculator shows the minimum resale price needed to break even. It compares that against a projected market value (depreciated toward the salvage value) and the accounting book value, so you can see whether the likely sale price is enough to make the investment worthwhile.

Depreciation and NPV

Depreciation spreads the asset cost over its useful life (straight-line here). NPV discounts all future cash flows back to today using your discount rate — a positive NPV means the investment clears your required return, a negative NPV means it falls short.
