What the Fleet Estimator Does

The Fleet EV Conversion Savings Estimator compares your existing internal combustion engine (ICE) fleet to a comparable EV fleet over a multi-year period. It combines fuel, energy, maintenance, vehicle cost, infrastructure, incentives, and tax assumptions to show the total cost impact of going electric.

In a few fields, you can see:

  • Estimated annual fuel + maintenance savings by switching to EVs.
  • Your projected 7-year (or 5 / 10-year) net savings after upfront costs.
  • A simple, interpretable payback period in years and months.
  • How much gasoline and CO₂ emissions your fleet can avoid each year.

It turns an EV conversion conversation from “this feels expensive” into “here’s the payback, year by year.”

Inputs You Control

The estimator is built around fields that fleet operators and finance teams actually have at their fingertips. You can customize everything that materially affects the business case.

Fleet & utilization

  • Fleet size (number of vehicles)
  • Miles driven per vehicle per year
  • Average ICE MPG
  • Current fuel price ($ / gallon)

Operating costs

  • Annual ICE maintenance cost per vehicle
  • Annual EV maintenance cost per vehicle
  • EV efficiency (miles per kWh)
  • Electricity cost ($ / kWh)

Vehicles & infrastructure

  • EV purchase price per vehicle
  • Incentives & rebates per vehicle
  • Resale value of existing vehicles
  • Total charging infrastructure cost (hardware, install, site work)
  • Analysis period (5, 7, or 10 years)

Environmental options

  • Toggle to include grid emissions when calculating net CO₂.
  • Set your own grid emissions intensity (kg CO₂ per kWh).

This lets you show both tailpipe CO₂ avoided and net impact after EV charging.

Tax & depreciation scenarios

  • Optional toggle for Section 179 & 168(k) bonus depreciation.
  • Business tax rate (%) for estimating tax savings.
  • Editable Section 179 limit and bonus depreciation percentage.
  • Optional override for “qualifying spend” if your CPA uses a custom base.

These fields help you see an estimated “after-tax” upfront outlay. Assumptions can be tuned with your accounting team.

Note: All tax and depreciation options are estimates for illustration only. Confirm actual treatment and eligibility with a qualified tax professional.

What You Get Back

Once your numbers are in, the estimator calculates a set of financial and environmental KPIs that can be dropped directly into presentations, board decks, or funding requests.

Financial metrics

  • Annual ICE fuel cost vs. annual EV energy cost for the full fleet.
  • Annual fuel + maintenance savings (ICE Opex − EV Opex).
  • Annual ICE operating expense vs. EV operating expense (fuel/energy + maintenance).
  • Upfront net outlay (after tax), factoring in EV purchases, incentives, resale, infrastructure, and estimated tax savings.
  • Multi-year net savings (5, 7, or 10 years), including upfront costs.
  • Payback period in years and months, if annual savings are positive.

Environmental impact

  • Annual gasoline avoided (gallons) across the fleet.
  • Annual tailpipe CO₂ avoided (kg).
  • Annual net CO₂ (kg), optionally including grid emissions from EV charging.
  • Multi-year net CO₂ reduction (tons), based on your analysis period.

This gives sustainability teams and lenders a clean way to connect capital decisions to emissions outcomes.

Visual Dashboards & Exports

The Fleet Estimator doesn’t just give you numbers – it also produces visual charts that tell the story:

  • Annual cost comparison chart showing ICE vs. EV operating costs.
  • Break-even timeline of cumulative net savings, including a clear zero line where EVs pay back.
  • Cost of gasoline vs. electric over time, with adjustable fuel and electricity escalation assumptions.
  • Environmental impact chart highlighting gasoline avoided and CO₂ benefits.

When you’re ready to document an opportunity or send results to your team, you can generate a downloadable CSV summary of key assumptions and outputs with a single click.

Pro tip: Drop these charts directly into your fleet electrification proposals, loan packages, or internal business cases.

Who the Fleet Estimator Is For

This tool is built for organizations that need to justify EV fleet investments with real numbers:

  • Fleet managers deciding whether to start a pilot or scale an existing EV program.
  • CFOs and finance teams evaluating total cost of ownership and payback timelines.
  • Sustainability and ESG teams quantifying CO₂ reductions from fleet projects.
  • Banks, lessors, and lenders underwriting EV fleet financing and infrastructure.
  • Consultants and developers building structured EV proposals for fleet clients.

RightSite can also pair these fleet-level savings with location-based analytics for charging infrastructure, so you’re not just choosing the right vehicles — you’re choosing the right places to charge them.
