Here's My Story
I'm a Tesla service tech by day and a garage tinkerer by night. Between fixing real cars, maintaining a family home, and stretching a household budget, I've spent years testing what actually saves money and time — and what sounds good on paper but fails in real life.
Efficient Wins exists because most efficiency content is either too shallow or too salesy. I built calculators that model every cost category I could think of — depreciation, shop downtime, tax credits — because you deserve the full picture before making a $40,000 decision.
What Makes This Site Different
- Tools first. The EV vs Gas calculator includes 20+ editable inputs. If it matters to the math, it's in there.
- Shown work. Year-by-year tables, cost breakdowns, methodology notes on every calculator.
- Honest defaults. Based on 2026 U.S. averages — but labeled as assumptions, not facts about your car.
- No hype. If keeping your gas car is cheaper, the calculator will tell you.
