CD70 Electric Conversion Payback Calculator
Change the inputs to your own mileage, fuel price, electricity tariff and conversion budget. The calculator shows the monthly running-cost difference and how many months of savings it takes to pay back the conversion — with every assumption visible so you can challenge it.
Calculate your own payback
Defaults are a typical light-commuter scenario using publicly referenced November 2026 Pakistani fuel prices. They are starting points, not recommendations.
How it works: petrol cost = monthly km ÷ km per litre × price per litre. Electricity cost = monthly km × Wh/km ÷ 1000 × tariff × (1 + charging losses). Monthly saving = petrol cost − electricity cost + avoided petrol maintenance. Payback = conversion cost ÷ monthly saving. The model intentionally excludes financing, resale value, battery replacement, downtime and insurance.
Worked examples
| Scenario | Monthly km | Conversion cost | Monthly saving | Payback |
|---|---|---|---|---|
| Light commuting | 600 | PKR 85,000 | PKR ~3,000 | ≈ 28 months |
| Daily commute (default) | 1,000 | PKR 150,000 | PKR ~4,600 | ≈ 33 months |
| Delivery / high utilisation | 1,800 | PKR 150,000 | PKR ~7,600 | ≈ 20 months |
| Fleet, 2,500 km/month | 2,500 | PKR 250,000 | PKR ~10,300 | ≈ 24 months |
Illustrative outputs from the stated default inputs. Pakistani coverage commonly cites 12–18 months for daily conversions; that result depends heavily on the battery cost, utilisation and the electricity tariff you actually pay. Changing the tariff or the conversion budget above will move the answer more than any other input.
Which input changes the answer most?
Monthly distance
Payback is almost inversely proportional to utilisation. A bike used 600 km/month takes roughly three times as long to pay back as the same bike used 1,800 km/month. Fleet and delivery conversions therefore have the strongest economics.
Battery cost and life
The battery is usually the largest item in a conversion. Lead-acid is cheaper upfront but needs earlier replacement; LiFePO4 costs more initially and generally survives more cycles and hot weather. Compare lifecycle cost, not purchase price.
Electricity tariff
At 30 Wh/km, 1,000 km uses about 30 kWh before charging losses. A change of PKR 10/kWh moves monthly cost by only about PKR 350 — smaller than most people expect.
Petrol price
Fuel price is the single biggest running-cost lever on the petrol side. At 55 km/L, a PKR 50/litre increase adds roughly PKR 900 per month at 1,000 km.
From estimate to quotation
The calculator estimates running cost, not the purchase price. Factory quotations depend on motor power and winding, controller rating, battery chemistry, harness, quantity, branding, freight and duties. Send your target specification and the Lahore team will return a landed-cost quote you can put back into the calculator.

Want the real number for your route?
Send the daily distance, payload and whether this is one bike or a fleet. We will match the motor, controller and battery to that duty cycle and quote it.
