This calculator produces directional ROI estimates by combining user-selected inputs with savings-rate assumptions grounded in published research and real-world municipal deployments. Below we document every formula, coefficient, and data source so you can audit or extend the model yourself.
1. Core Formulas
Estimated Annual Savings
Savingslow = Budget × rlow
Savingshigh = Budget × rhigh
where rlow and rhigh are the use-case-specific savings rates (see table below).
Midpoint Annual Savings
Savingsmid = (Savingslow + Savingshigh) / 2
Cumulative Savings (Year N)
CumulativeN = Savingsmid × N
Linear accumulation — no compounding or discount rate is applied. This is deliberately conservative: it excludes the compound value of reinvested savings and learning-curve acceleration.
Net ROI (over projection period T)
Net ROI = (Savingsmid × T) − Implementation Cost
ROI Percentage
ROI % = (Net ROI / Implementation Cost) × 100
Payback Period
Payback (months) = ⌈Implementation Cost / (Savingsmid / 12)⌉
Result is rounded up to the nearest whole month. Because annual savings significantly exceed implementation costs in most configurations, payback typically falls under 1 month.
Implementation Cost
Impl. Cost = Population Estimate × Cost per Capita
Each city tier maps to a reference population (see Section 2). Each use case defines a per-capita cost coefficient (see Section 3).
2. City Size Assumptions
Each city tier maps to a default annual planning/infrastructure budget and a reference population used to compute implementation cost. Users may override the budget; the population estimate stays fixed.
| City Tier | Population Range | Reference Population | Default Budget |
|---|---|---|---|
| Small City | 50,000 – 150,000 | 100,000 | $15,000,000 |
| Mid-Size City | 150,000 – 500,000 | 300,000 | $60,000,000 |
| Large City | 500,000 – 2,000,000 | 1,000,000 | $250,000,000 |
| Major Metro | 2,000,000+ | 3,000,000 | $800,000,000 |
Budget per capita: Default budgets range from $150/person (small city) to $267/person (major metro), reflecting higher infrastructure density and complexity in larger municipalities.
3. Use-Case Savings Rates & Operational Impact Coefficients
Each use case applies a distinct pair of savings rates (rlow, rhigh) to the budget, a per-capita implementation cost, and a fixed set of operational impact percentages. These are derived from the research sources listed in Section 7.
| Use Case | rlow | rhigh | $/capita | Efficiency | Cycle Time | Carbon |
|---|---|---|---|---|---|---|
| Infrastructure Mgmt | 20% | 35% | $3.00 | 30% | 40% | 12% |
| Traffic & Mobility | 15% | 30% | $2.50 | 25% | 35% | 18% |
| Energy & Utilities | 18% | 31% | $2.80 | 28% | 30% | 25% |
| Urban Planning & Zoning | 12% | 25% | $1.80 | 20% | 45% | 8% |
| Emergency & Resilience | 10% | 22% | $2.20 | 22% | 50% | 10% |
How to read this table: A mid-size city ($60M budget, 300K population) selecting "Infrastructure Management" would see annual savings of $60M × 20% = $12.0M (low) to $60M × 35% = $21.0M (high), with implementation cost of 300,000 × $3.00 = $900K.
4. Implementation Cost Matrix
Combining the reference population (Section 2) with the per-capita cost (Section 3) produces the following implementation costs:
| Use Case | Small (100K) | Mid-Size (300K) | Large (1M) | Metro (3M) |
|---|---|---|---|---|
| Infrastructure Mgmt | $300K | $900K | $3.0M | $9.0M |
| Traffic & Mobility | $250K | $750K | $2.5M | $7.5M |
| Energy & Utilities | $280K | $840K | $2.8M | $8.4M |
| Urban Planning & Zoning | $180K | $540K | $1.8M | $5.4M |
| Emergency & Resilience | $220K | $660K | $2.2M | $6.6M |
What's included: Platform licensing & setup, data integration (IoT sensors, GIS, SCADA feeds), model calibration, staff training, and first-year vendor support. Excludes ongoing subscription fees and hardware procurement.
5. Worked Example
Scenario: Mid-Size City • Infrastructure Management • 5-Year Projection • $60M Budget
| Annual Savings (low) | $60M × 0.20 = $12.0M |
| Annual Savings (high) | $60M × 0.35 = $21.0M |
| Midpoint Annual Savings | ($12.0M + $21.0M) / 2 = $16.5M |
| Implementation Cost | 300,000 × $3.00 = $900K |
| 5-Year Cumulative Savings | $16.5M × 5 = $82.5M |
| Net ROI | $82.5M − $0.9M = $81.6M |
| ROI % | $81.6M / $0.9M × 100 = 9,067% |
| Payback Period | $0.9M / ($16.5M / 12) = 0.65 mo → 1 month |
6. Key Assumptions & Limitations
- Linear savings accumulation. Cumulative savings grow linearly (no compounding). In practice, learning-curve effects and expanded sensor coverage often accelerate savings in years 2–3, making linear projection conservative.
- No discount rate / NPV. All figures are nominal. A data-driven user may wish to apply a 3–5% municipal discount rate. At 4% over 5 years, the present value of $82.5M cumulative savings drops to ~$73.5M — still strongly positive.
- Savings rates are budget-proportional. The model assumes savings scale linearly with budget. This holds well for mid-range budgets but may overstate savings for very small deployments (where fixed costs dominate) or very large ones (where diminishing marginal returns apply).
- Implementation cost is a one-time fixed value. Ongoing operational costs (cloud hosting, data feeds, FTE allocation) are not modeled. Industry benchmarks suggest annual OpEx of 15–25% of the initial implementation cost.
- Use-case isolation. The calculator models one use case at a time. Multi-use-case deployments typically share platform costs and can achieve higher aggregate ROI than the sum of individual estimates.
- Operational impact metrics are indicative. Efficiency gain, planning cycle reduction, and carbon reduction percentages are drawn from the research sources below and represent achievable benchmarks, not guaranteed outcomes.
7. Sensitivity Analysis
How much do results change if the assumptions shift? The table below shows Net ROI for the mid-size city infrastructure scenario under different savings-rate and cost assumptions.
| Scenario | Savings Rate | Impl. Cost | 5-Yr Net ROI | ROI % |
|---|---|---|---|---|
| Conservative (−50%) | 10% – 17.5% | $1.35M (+50%) | $39.9M | 2,956% |
| Base Case | 20% – 35% | $900K | $81.6M | 9,067% |
| Optimistic (+25%) | 25% – 43.75% | $675K (−25%) | $102.5M | 15,178% |
| Break-Even Threshold | 0.30% | $900K | $0 | 0% |
Key takeaway: Even cutting savings rates in half and increasing implementation cost by 50%, the 5-year ROI remains ~$40M (2,956%). The model breaks even at a combined savings rate of just 0.30% of budget — well below any published benchmark.
