Building Stattraq: a profitability calculator for GTA gig drivers
We built a free calculator that shows rideshare and delivery drivers their true take-home per hour after fuel, depreciation, insurance, CPP, and taxes. A note on why and how.
Stattraq is a small product we built in 2025 and still maintain. It’s a free web calculator that shows GTA rideshare and delivery drivers what they’re actually making per hour after all costs. No signup, no data collection.
This post is a short note on why we built it and what’s under the hood.
Why a calculator
A lot of the drivers we’ve talked to — friends, people we met on trips, messages from the contact form — have the same question: am I actually making money?
The platform dashboards aren’t helpful here. They show gross earnings. The real number is gross earnings minus:
- Fuel.
- Vehicle depreciation (often the largest hidden cost).
- Insurance, including the rideshare endorsement (OPCF 6C in Ontario).
- Maintenance, tires, oil changes.
- Parking and tolls.
- Income tax and CPP, which you pay yourself as a self-employed driver.
The answer, after you actually run the numbers, is often below the Ontario minimum wage. That’s a useful thing to know before you decide to keep driving 40 hours a week.
What we built
Stattraq takes your inputs — vehicle, fuel efficiency, hours driven, gross earnings, platform — and returns a per-hour and per-kilometre number that accounts for everything above. It uses current Canadian federal and Ontario tax brackets, the 2025 CPP rate, and the Ontario minimum wage for a comparison point.
The design choices that matter:
- No account required. Everything runs in the browser and saves to
localStorage. No one needs a login to use it. - No data collection. There’s no telemetry and no backend database for user inputs.
- Exportable. You can export a scenario as JSON or print it to PDF.
- Covers the major platforms. Uber, Lyft, DoorDash, SkipTheDishes, Instacart, and generic custom entries for anything else.
The stack
Nothing exotic:
- Next.js 16 with the App Router, mostly for the static pages and the calculator form.
- TypeScript throughout.
- Tailwind CSS v4 for styling.
- Supabase — present but barely used. Reserved for a future feature (shared scenarios, fleet accounts) we haven’t shipped yet.
- Vercel for hosting.
- JSON-LD structured data for SEO.
The calculator itself is pure client-side code. It has to be, since the privacy promise is that nothing leaves the browser.
What’s next
A short roadmap, for transparency:
- Expand beyond the GTA to the rest of Ontario (Ottawa, Hamilton, KW), then other provinces with province-specific tax engines.
- Platform-specific calculators with each platform’s actual fee structures.
- OBD-II hardware integration for automatic mileage and fuel-consumption tracking. This one is speculative — we’d need someone to pilot it.
It’s a free tool and not a growth priority for us, so the pace is deliberate. But it works today and it’s honest, which is the whole point.
