TMS Business-Case Calculator

A business case is arithmetic on honest inputs, not a vendor's slide. Put in your numbers — hours a system removes, cash you could mobilize, fees and losses it prevents — and see the annual benefit, payback and ROI. It's the tool behind the TMS business-case guide and the total-cost-of-ownership breakdown.

Summary
# TMS business case

## Annual benefit
Labour saved:        $0  (0 h/wk x $0/h x 52)
Cash mobilized:      $0  ($0 x 0%)
Bank/fee saving:     $0
Loss avoided:        $0
Total annual benefit $0

## Cost
Annual licence/run:  $0
Implementation (1x): $0

## Result
Net annual benefit:  $0
Payback:             never (net annual benefit is not positive)
Over 3 years:  benefit $0 - cost $0 = $0 net
Simple ROI (3 yr): —

(Simple/undiscounted ROI — it does not discount future cash flows.)

Every figure here is arithmetic on the numbers you entered — the tool supplies no benchmarks and makes no assumptions on your behalf. The ROI shown is simple/undiscounted: it doesn't discount future cash flows, so treat it as a directional case, not a formal NPV. A credible business case uses inputs you can defend to your CFO, not round numbers from a vendor. Nothing you type leaves your browser.

How this works

Methodology

Annual benefit = labour saved (hours × rate × 52) + cash mobilized (idle cash × extra yield) + fee savings + losses avoided. Net annual benefit subtracts the annual licence; payback is implementation ÷ net annual benefit; ROI is (total benefit − total cost) ÷ total cost over your horizon.

Assumptions

  • Every figure is yours — the tool supplies no benchmarks and no defaults.
  • Benefits are steady across the horizon (no ramp-up or decay is modelled).
  • Cost is the annual licence + run cost plus a one-off implementation.

Limitations

  • ROI is simple and undiscounted — it does not discount future cash flows to present value, so it is not an NPV or IRR.
  • It assumes benefits are realized; a failed or delayed project earns none of them.
  • Soft benefits (better decisions, control, resilience) are not quantified here — make that case separately.
