**Step:** 1000

**Outputs:**

#### Annual labor value

**Key:** labor

**Expr:** hours_week * 52 * rate

**Format:** currency

**Description:** Hours saved times 52 weeks times loaded rate.

#### One-time cash released from inventory

**Key:** inv_cash

**Expr:** inventory * reduction / 100

**Format:** currency

#### Annual carrying cost saved

**Key:** carry_save

**Expr:** inv_cash * carry / 100

**Format:** currency

#### Total annual benefit

**Key:** benefit

**Expr:** labor + carry_save + expedite

**Format:** currency

**Primary:** true

#### Annual running cost

**Key:** cost_year

**Expr:** monthly_fee * 12

**Format:** currency

#### Net annual benefit

**Key:** net

**Expr:** benefit - cost_year

**Format:** currency

#### Payback period

**Key:** payback

**Expr:** if(gt(net, 0), project / net * 12, 0)

**Format:** months

**Primary:** true

**Description:** Zero means the net benefit is not positive, so there is no payback.

#### Three-year ROI

**Key:** roi3

**Expr:** if(gt(project, 0), (net * 3 - project) / project * 100, 0)

**Format:** percent

**Chart:**

#### Net annual benefit vs admin hours saved

**Type:** line

**X:** hours_week

**From:** 0

**To:** 60

**Steps:** 30

**Series:**

- net

**Disclaimer:** Estimates only. Cash released from inventory is one-time and is not included in the annual benefit; only its carrying cost saving is. Use measured numbers from your own operation.

## Content

**Intro:** Owners ask whether a cloud MRP will pay for itself. This calculator turns four common benefits into a payback estimate: admin time saved, lower inventory, avoided expediting and the running cost against project cost.

**Sections:**

#### How to use it

**Body:** Enter realistic hours saved per week across all roles, such as the planner no longer building lists in Excel and the office no longer re-keying orders. Use a loaded labor rate with payroll burden. Enter current inventory value and a conservative reduction percentage, plus carrying cost, which commonly includes capital, storage, insurance and obsolescence. Then add expedite costs you expect to avoid, subscription fees and the one-time project cost.

**Bullets:**

- Use measured hours, not hopes
- Take a conservative inventory reduction
- Include staff time in project cost
- Test several scenarios with the sliders

#### The formulas

**Body:** Annual labor value is hours per week times 52 times the rate. Cash released from inventory is inventory times the reduction percentage, and the annual saving from it is that cash times the carrying cost rate. Total annual benefit adds labor, carrying saving and avoided expedites. Net benefit subtracts twelve months of subscription. Payback in months is project cost divided by net annual benefit, times twelve.

#### Reading the result

**Body:** A payback under 24 months is typical for plants that move from spreadsheets to an integrated planning tool, but your numbers decide. Check the chart: if the net benefit only turns positive at a high number of hours saved, the case rests on a single assumption and needs evidence. The three-year ROI shows return on project cost after running fees.

#### Common mistakes

**Body:** Counting every saved hour as cash when no one is laid off or overtime reduced, assuming a large inventory cut in month one, and leaving out the work to clean data. Treat labor savings as capacity that allows growth without hiring, and be honest about which benefits are cash and which are capacity.

**Cta:** Netray can extract your actual order, purchasing and inventory data to ground these assumptions in real numbers.

**Faq:**

#### How much inventory reduction is realistic?

**Answer:** It depends on how poor planning is today. Plants planning from spreadsheets often find excess on slow items, but results vary widely. Start with a low single-digit to 10 percent scenario and validate with data.

#### Is the released inventory cash counted as benefit?

**Answer:** Not in the annual benefit, because it is one-time. Only the carrying cost saved is counted. You can treat the cash as an extra one-time gain in your own case.

#### What carrying cost percentage should I use?

**Answer:** Many companies use 15 to 30 percent per year, combining cost of capital, storage, insurance, shrinkage and obsolescence. Ask your accountant for your own rate.

#### Why is payback zero?

**Answer:** The calculator shows zero when annual net benefit is zero or negative, meaning the running cost exceeds the benefit and the project does not pay back under these inputs.
