See the real value of switching to ARA.
A transparent calculator built for both daily commuters and commercial operators. Every assumption is editable, every number is explained, and nothing is exaggerated. Adjust inputs to match your reality.
Step 1
What kind of use are you calculating for?
The logic, defaults, and benchmarks change based on your context. Pick the one that matches your usage best.
Step 2 · Assumptions
Two Wheeler · Personal commute
How far you ride or operate per active day.
Real-world average — lower than brochure figures.
Use your bill's average. Commercial slabs differ from domestic.
ARA-tested figures range 25–70 Wh/km depending on category.
Brake pads, tyres, periodic checks. No oil, no filters.
Defaults reflect typical Bangladesh-market figures. Edit any value to match your route, tariff, or vehicle — the result updates live.

Insights from your assumptions
~93% lower energy cost per km
At your assumptions, running an ARA EV costs ৳0.20/km vs ৳2.71/km on petrol.
Predictable monthly savings
For a daily commuter doing ~35 km, monthly fuel goes from ৳2,280 to ৳170.
Lower scheduled maintenance
EVs avoid oil, filters, clutch wear, and complex engine service — about ৳4,500 less per year on routine upkeep at typical use.
Beyond the rupees
Ownership value, not just energy savings.
The calculator shows operating cost. ARA's full value comes from how the vehicle is supported throughout its life — warranty, parts, and service uptime that protect your investment.
Warranty
Up to 5 years on LFP packs, 3 years on motor — protecting the most valuable component.
Service network
Nationwide coverage with priority SLAs for commercial operators.
Parts continuity
7-year commitment on spare-parts availability for every model line.
Predictable economics
Stable per-km cost — insulated from fuel-price volatility.
FAQ
Calculator questions
Transparency about how the numbers work — and what they deliberately don't include.
- Per-km energy cost = fuel price ÷ km per litre/m³. EV per-km cost = electricity tariff × kWh per km. Monthly figures multiply by daily distance × operating days. Yearly adds your maintenance assumptions. We deliberately avoid resale value, depreciation curves, or financing math — those depend on too many factors to estimate honestly.
- Yes. Every input — distance, tariff, fuel price, mileage, maintenance, EV consumption — is editable. The result updates live so you can stress-test the figures against your real usage.
- A delivery operator doing 90 km daily on diesel has very different economics from a commuter doing 30 km on petrol. We split the flow so the defaults, comparator fuel, and insights stay relevant to your context.
- They're directionally accurate — useful for a confident decision, not a guarantee. Real-world cost varies with terrain, load, ambient temperature, charging behaviour, and tariff slab. We round outputs to avoid false precision.
- Not in this calculator. ARA's LFP batteries carry up to 5 years of warranty and the technology shows graceful degradation, not sudden failure. We choose not to model speculative replacement cost rather than inflate either direction.
