How do you calculate the ROI of a TMS?
Add the annual value of billing and settlement hours saved, accessorial revenue captured, and the carrying cost of cash freed by a shorter DSO, then subtract the annual subscription to get annual net benefit. Payback months equals the one time implementation cost divided by monthly net benefit, and 3 year net return equals three years of net benefit minus the implementation cost.
Founded in 2008 by Scott Elliott in Minnesota, Strong Tower Consulting, LLC (Minnesota File No. 2948628-2) has advised carriers for more than 18 years on TMS implementation, selection, and the integration work that decides whether a project pays back.
Every default below is an example value chosen to show how the math behaves. None is an industry benchmark. Replace each one with your own quote, payroll, and accounts receivable records.
Vendor services, data migration, ELD and EDI integration, internal time, and training.
Recurring yearly fee plus hosting and support. Multiply per truck per month quotes out to a year.
Wage plus payroll tax and benefits for the staff whose hours are saved.
Detention, layover, lumper, and other accessorials you expect to bill that are missed today. 0.5 is an example, not a benchmark.
Days sales outstanding you expect to remove by invoicing faster with complete paperwork.
Your line of credit rate or the return you expect on redeployed cash.

|---|---|---|---|---|---|
| Year 1 | $0 | $0 | $0 | $0 | $0 |

Show the math
- Labor benefit = hours per week x 52 x loaded rate
- Accessorial benefit = annual revenue x lift percent
- Working capital benefit = (annual revenue / 365) x DSO days reduced x cost of capital percent
- Annual gross benefit = labor + accessorial + working capital
- Annual net benefit = gross benefit - annual subscription
- Payback months = implementation cost / (annual net benefit / 12)
- 3 year net return = 3 x annual net benefit - implementation cost
- 3 year ROI percent = 3 year net return / (implementation cost + 3 x subscription) x 100
How the model works
Every figure above comes from the eight inputs on this page. Nothing is pulled from another fleet or a vendor case study.
- Price the hours saved. Billing and settlement hours saved per week, times 52 weeks, times your loaded labor cost per hour. This is the benefit that is easiest to verify after go live because payroll shows it.
- Add the accessorial lift. Annual revenue times the lift percent. Enter the share of revenue you believe is earned but not billed today. Our detention revenue leakage calculator can help you size this input from stop level data.
- Add the working capital benefit. Revenue divided by 365 gives revenue per day. Times DSO days reduced gives the cash released one time. Times your cost of capital percent gives the recurring annual value of holding that cash instead of borrowing it.
- Subtract the subscription. Annual gross benefit minus the recurring annual fee is the annual net benefit.
- Recover the implementation cost. Payback months divides the one time cost by one twelfth of the annual net benefit. If net benefit is zero or negative, the cost is not recovered and the model says so.
- Look out three years. Three years of net benefit minus the implementation cost is the 3 year net return. Dividing that by total 3 year spend (implementation plus three subscriptions) gives the 3 year ROI percent.
What this model leaves out
The three benefit streams here are the ones a carrier can usually prove with payroll, invoice registers, and an aging report. A TMS can also change outcomes that are harder to put a number on: fewer missed appointments because dispatch sees the plan, fewer rate disputes because the rate confirmation drives the invoice, and cleaner data for SQL data mining and lane profitability work. If you can measure those gains in your own books, add them to the accessorial lift or treat them as a separate line. Do not borrow a figure from a vendor brochure.
The model also treats the implementation cost as a single year one outlay. Real projects often spread services and integration spend across two or three quarters, and the benefit ramps in rather than switching on. If your ELD and EDI integration is on the critical path, assume the labor and DSO benefits start only after that integration is live.
Reading the payback number
A payback under 12 months means the project returns its one time cost inside the first subscription year. A payback between 12 and 36 months is common for mid sized carriers replacing a legacy system, because migration and training costs land up front. A payback beyond 36 months, or a result of not recovered, usually means either the subscription is high relative to the fleet or the benefit inputs are conservative. Change one input at a time and watch which lever moves the result most. That sensitivity is more useful than the headline number.
Carriers weighing this decision alongside broader technology priorities often ask for fractional freight CIO support so the TMS case is judged against the rest of the roadmap rather than in isolation.

Frequently asked questions
What counts as a TMS benefit in this calculator?
The model adds three benefit streams: billing and settlement labor hours saved at your loaded labor rate, accessorial revenue captured as a percent of annual revenue, and the carrying cost of cash freed when days sales outstanding falls. Softer gains such as fewer service failures or better rate decisions are not counted. Add them separately if you can measure them.
Why is the working capital benefit so much smaller than the DSO reduction suggests?
Cutting DSO by five days on 25 million dollars of revenue frees about 342,000 dollars of cash one time. That cash is not income. The recurring benefit is what that cash would otherwise cost you to borrow or what it earns when redeployed, which is the freed cash times your cost of capital percent. The calculator reports that annual carrying cost, not the one time cash release.
How should I set the implementation cost and subscription inputs?
Implementation cost should include vendor services, data migration, integration work for ELD and EDI, internal staff time, and training. Subscription or license cost is the recurring annual fee plus hosting and support. If your vendor quotes a per truck per month fee, multiply it out to a yearly figure before entering it.
Are the default numbers industry benchmarks?
No. Every default is an example value chosen to show how the math behaves. Strong Tower Consulting does not publish a benchmark TMS return and does not guarantee that any project will reach the result shown. Replace every example with your own records before you rely on the output.
