Public Transport vs Car: Which Actually Costs Less?
Is your car costing more than you think?
Most people dramatically underestimate how much their car costs. The monthly payment gets all the attention, but it's only one piece of a much larger picture. Insurance, fuel, maintenance, parking, and depreciation can easily push total car ownership costs to $800β$1,200 per month β even for a modest vehicle. On the other side, a transit-first lifestyle combining a monthly pass, rideshare apps for convenience trips, and occasional car rentals often runs $150β$350 per month in most cities. The gap is frequently $500β$900 per month β or $6,000β$10,000 per year. The decision isn't purely financial. Car ownership provides flexibility and convenience that many people value highly. But most people who say they "need" a car have never actually run the numbers. This calculator helps you do exactly that. Enter your real car costs β including the depreciation your car loses every year whether you drive it or not β and compare against your realistic transit scenario. The result often surprises people.
- Β·Depreciation calculated as a fixed percentage of current car value per year
- Β·Fuel cost calculated from monthly miles, MPG, and gas price per gallon
- Β·Transit costs include pass, rideshare, and car rental/sharing
- Β·Opportunity cost (investing savings) calculated at 7% annual return for 5-year projection
- βYou're considering giving up your car to save money in a city with transit
- βYou want to know if your car is your largest monthly expense
- βYou're moving to a new city and evaluating whether to bring your car
- βYou're deciding whether to buy a second car for your household
- βYou want to calculate how much you'd save by selling your car and switching to transit
Priya lives in Chicago and pays $520/month on a car loan, $180/month for insurance, $120/month in parking, $85/month in gas, and $80/month in maintenance. Her car, worth $22,000, depreciates $330/month. Her total monthly car cost: $1,315. She researches transit: a $105 Ventra monthly pass plus $80 in Uber rides and $30 for occasional Zipcar trips = $215/month. Switching to transit would save Priya $1,100/month β $13,200 per year β and if she invests that difference, she'd have over $76,000 in 5 years.

About This Calculator
This public transport vs car calculator computes and compares total monthly costs in real time from 12 inputs. Car total = carPayment + insurance + gas + maintenance + parking + registration + depreciation. Transit total = transitPass + rideshare + bikeshare. Annual savings = (carMonthly β transitMonthly) Γ 12. 5-year invested value = annualSavings Γ ((1.07^5 β 1) / 0.07) compounding at 7%. Time value = (hoursSaved Γ 4.33 Γ hourlyRate) / 60. Score = clamp(50 + (annualSavings / 12000) Γ 50). Tiers: Strongly Transit (70+), Lean Transit (58+), Nearly Equal (42+), Lean Car (30+), Strongly Car. All 12 inputs update in real time.
The Breakdown tab renders a donut PieChart of 7 car cost categories (payment/insurance/gas/maintenance/parking/registration/depreciation, each with a distinct color, inner radius 58, outer 95, dark stroke) with side legend showing category name, %, and $/mo β then a grouped BarChart of car vs transit at 3 time horizons (monthly/annual/5-year, red/green side-by-side bars with LabelList dollar labels). The Timeline tab renders a dual AreaChart of cumulative spending over 10 years (car red/gradient vs transit green/gradient, 0-yr to 10-yr, showing the gap widening) plus 3 year-milestone boxes (1yr/5yr/10yr savings). The Scenarios tab renders a BarChart of annual savings for 5 scenarios (current/paid off/high parking/remote work/premium transit, ReferenceLine at current and at 0, LabelList dollar labels) then a scenario detail table with car, transit, savings, and winner badge columns. The Insights tab shows 4 key insights (cost comparison summary, 5-year compounded value, time value analysis, leverage points) and 4 conditional action plan items.
