Rules of Thumb for Car Buying

The 20/4/10 Rule

Put down at least 20%, finance the vehicle for no longer than 4 years, and keep total monthly transportation costs under 10% of your gross income.

The 3-Year Depreciation Hit

A new car loses roughly 40% to 50% of its value in the first three years. Buying a 3-year-old off-lease vehicle is often the mathematical sweet spot for value.

10% Maintenance Fund

Set aside at least 10% of the vehicle's purchase price annually into a sinking fund to comfortably cover tires, oil changes, insurance, and sudden repairs.

Frequently Asked Questions

What is the True Cost of Ownership (TCO) for a car?

Most buyers only look at the monthly EMI. TCO factors in the purchase price, interest, fuel, insurance, maintenance, and the biggest hidden cost: depreciation. A cheaper car with high depreciation can cost you more over 5 years than a slightly more expensive car that holds its value.

Is charging an EV always cheaper than buying petrol/gas?

Usually, but not always. If you exclusively charge at home using off-peak electricity rates, an EV is significantly cheaper. However, relying entirely on commercial Level 3 DC Fast Chargers (like Superchargers) can sometimes cost nearly as much as fueling an efficient hybrid.

How do gig economy drivers miscalculate their earnings?

Many Uber or DoorDash drivers only subtract the cost of gas from their gross earnings. To find your true net profit, you must also subtract the per-mile cost of depreciation, increased maintenance, commercial insurance upgrades, and the self-employment tax burden.
