How do you calculate software ROI payback period?

Subtract annual support cost from annual savings to get net savings, then divide the upfront investment by that net. With $25,000 invested, $18,000 saved and $2,500 support, net is $15,500 and payback is 25,000 / 15,500 = about 1.61 years.

What is a good payback period for planning software?

For manufacturing software, a payback under two years is generally strong and under three years is acceptable. The 1.61-year payback in the example clears that bar comfortably.

Why subtract support cost from savings?

License, hosting, and support fees recur every year and eat into the gross savings. Netting them out — $18,000 minus $2,500 here — gives the $15,500 of real annual benefit that actually pays down the investment.

What is the five-year net value?

It is five years of net savings minus the upfront investment. Here five years at $15,500 is $77,500, less the $25,000 investment, leaving $52,500 of net value over the horizon.

Does this account for the time value of money?

No. It uses simple, undiscounted cash flows. For a large purchase, run an NPV with your discount rate as well, since the 1.61-year payback and $52,500 net value will both shrink modestly once discounted.

ROI vs payback period — which should I quote?

Quote both. Payback (1.61 years) answers how fast you recover cash; the five-year net value ($52,500) and ROI answer how much total benefit you capture. Committees usually want the payback first.

Manufacturing Project Portfolio & Capex calculator

Capex Planning Software ROI Calculator

Capex Planning Software ROI tells you how fast a planning or portfolio tool pays for itself once you net its ongoing support cost against the savings it delivers. Operations finance leaders and IT sponsors use it to justify the spend to a steering committee that wants a payback in years, not promises. Subtracting annual support from gross savings gives the true net benefit, and dividing the upfront investment by that net yields a payback period anyone can sanity-check. The five-year net value then shows the longer-run case once the tool is paid off.

What this calculator does

Estimate capex planning software roi for manufacturing project portfolio and capex using production-ready inputs so teams can screen a capital project before a detailed business case.
Use it when capex planning software roi in manufacturing project portfolio and capex is being compared against another manufacturing project portfolio and capex project for the same budget.
It nets annual support cost out of annual savings, divides the upfront investment by that net to get a payback period, and projects the five-year net value.

Formula used

Net annual capex planning software roi savings = annual capex planning software roi savings - annual capex planning software roi support cost
Capex planning software roi payback period = capex planning software roi investment ÷ net annual savings

Inputs explained

Capex planning software investment:
Annual savings from the software:
Annual software support and license cost:

How to use the result

Use it when building the business case for a capex-planning, portfolio, or estimating software purchase or renewal.
It treats savings and support as flat annual figures and ignores the time value of money, so it overstates value slightly versus a discounted-cash-flow analysis.
