Two ways to pay for the same trips
Uber and your own car charge for the same trips in opposite ways. Uber charges per ride: rides a week × fare × 52 / 12 a month, because there are 52 weeks in a year and 12 months. At 5 rides a week and $18 a ride, that is 5 × 18 × 52 / 12 = $390.00 a month, or 5 × 18 × 52 = $4,680.00 a year. Your own car charges per month whether you drive or not: payment + insurance + gas + maintenance + parking. At $350 + $150 + $120 + $80 + $50, that is $750.00 a month, or $9,000.00 a year. Uber wins by $360.00 a month and $4,320.00 a year — the two verdicts agree here, but both are stated, because they do not always agree when the numbers change. The car-equivalent cost per ride is the car’s monthly cost divided by the rides a month: $750.00 / (5 × 52 / 12) = $34.62 a ride, against Uber’s $18.00. The assumption that matters: the car is driven ONLY for these rides. If you drive more, the car looks better, because the fixed costs spread over more trips; if you ride more, Uber looks worse, because every extra ride is another $18.
| Measure | Uber | Own car | Winner |
|---|
| Monthly | $390.00 | $750.00 | Uber by $360.00 |
| Yearly | $4,680.00 | $9,000.00 | Uber by $4,320.00 |
| Per ride | $18.00 | $34.62 | Uber by $16.62 |
| At 3 rides a week | $234.00/mo | $750.00/mo | Uber by $516.00 |
| At 10 rides a week | $780.00/mo | $750.00/mo | Car by $30.00 |
| Paid-off car, free parking | $390.00/mo | $350.00/mo | Car by $40.00 |
At the defaults — 5 rides a week, a $18 fare, a car at $350 + $150 + $120 + $80 + $50 = $750.00 a month — Uber is $390.00 a month and $4,680.00 a year, the car is $750.00 a month and $9,000.00 a year, and Uber wins by $360.00 a month / $4,320.00 a year. The car-equivalent cost per ride is $34.62. Check the identities: rides × fare × 52/12 = Uber monthly, and the car parts sum to $750.00 a month.
The worked example, line by line
Setup: 5 rides a week, fare $18, car payment $350, insurance $150, gas $120, maintenance $80, parking $50 a month.
Line 1 — the rides a month. 5 × 52 / 12 = 21.6667 rides a month. There are more rides in a month than 4 weeks’ worth, because a month is 4.3333 weeks.
Line 2 — Uber monthly. 21.6667 × $18 = $390.00.
Line 3 — Uber yearly. 5 × 18 × 52 = $4,680.00.
Line 4 — the car monthly. $350 + $150 + $120 + $80 + $50 = $750.00.
Line 5 — the car yearly. $750.00 × 12 = $9,000.00.
Line 6 — the verdicts. Monthly: $750.00 − $390.00 = $360.00, Uber wins. Yearly: $9,000.00 − $4,680.00 = $4,320.00, Uber wins.
Line 7 — the cost per ride. $750.00 / 21.6667 = $34.62 a ride for the car, against Uber’s $18.00.
Reverse: the fare that ties the $750.00/mo car at 5 rides a week is $34.62 (exact $34.6154); at $34.62 Uber is $750.10/mo, ten cents over, and at $34.61 it is $749.88. The rides a week that tie the car at an $18 fare are 9.62/wk (exact 9.6154/wk); at 9.62/wk Uber is $750.36/mo, and at 9.61/wk it is $749.58. The own-car monthly cost that ties Uber is $390.00. The car payment that ties Uber is −$10.00 — impossible: running costs alone ($400.00/mo) already exceed the $390.00/mo Uber bill, so at 5 rides a week no car payment can ever tie; the tie only happens by riding more (9.62 rides a week). At a $25 fare, the tying rides are 6.92/wk (exact 6.9231/wk).
Every branch, checked
Rides 3 a week: Uber is $234.00/mo; Uber wins by $516.00. Fewer rides make Uber cheaper still, because the car’s fixed costs do not fall.
Rides 10 a week: Uber is $780.00/mo; CAR WINS by $30.00 (FLIP). The car-equivalent cost per ride falls to $17.31, below Uber’s $18.00. Ten rides a week is the flip: the tie is at 9.62 rides a week.
Fare $25: Uber is $541.67/mo; Uber wins by $208.33. A $7 fare rise costs $151.67 a month at 5 rides a week.
Fare $12: Uber is $260.00/mo; Uber wins by $490.00. Short cheap rides are Uber’s best case.
Payment $200/mo: the car is $600.00/mo; Uber wins by $210.00; car-equivalent cost per ride $27.69.
Payment $0/mo (paid-off car): the car is $400.00/mo; Uber wins by $10.00; car-equivalent cost per ride $18.46. A paid-off car almost ties Uber at 5 rides a week — but only almost.
Payment $0 AND parking $0: the car is $350.00/mo; CAR WINS by $40.00 (FLIP); car-equivalent cost per ride $16.15. A paid-off car with free parking beats Uber at 5 rides a week.
Insurance $250/mo: the car is $850.00/mo; Uber wins by $460.00; car-equivalent cost per ride $39.23.
Gas $200/mo: the car is $830.00/mo; Uber wins by $440.00; car-equivalent cost per ride $38.31.
Parking $150/mo: the car is $850.00/mo; Uber wins by $460.00; car-equivalent cost per ride $39.23. Parking is the cost people forget: $150 a month is $1,800 a year.
Reverse — the other way round: the tying fare is $34.62 (exact $34.6154); the tying rides are 9.62/wk (exact 9.6154/wk); the tying car cost is $390.00; the tying payment is −$10.00, impossible; at a $25 fare the tying rides are 6.92/wk (exact 6.9231/wk).
What the defaults assume
The model assumes the car is driven ONLY for these rides, so the gas, maintenance, and parking are for these trips alone. It assumes the Uber fare is the average including tip, the car payment is the monthly payment, and the insurance, gas, maintenance, and parking are monthly averages. It leaves out the car’s purchase price beyond the payment, depreciation, registration, and the value of your time — and it leaves out surge pricing, wait times, and the freedom of having a car in the driveway. With 0 rides a week, Uber is $0.00 and wins by $750.00 — the car still costs $750.00 a month whether you drive it or not. With a $0 fare, Uber is $0.00. With all car costs at $0, the car is $0.00 and wins by $390.00. Rounding convention: totals are computed from unrounded values, so rounded parts may differ by a cent from their rounded sum; the reverses are nearest-cent solutions, and the exact unrounded figures ($34.6154, 9.6154, 6.9231) are stated wherever the rounded figures appear.

Who uses this
- The commuter taking 5 Ubers a week: they learn Uber costs $390.00 a month against the car’s $750.00 — so they know Uber wins by $360.00 a month, and they check the 10-rides branch (car wins by $30.00) before assuming Uber always wins.
- The driver with a paid-off car: they learn the car costs $400.00 a month and Uber still wins by $10.00 — so they know the paid-off car almost ties, and they check the free-parking branch (car wins by $40.00) before deciding whether the car is really cheaper.
- The city dweller paying $150 a month to park: they learn parking alone is $1,800 a year — so they know the car is $850.00 a month with parking, and they check the tying fare ($34.62) before assuming the car is the cheap option.
- The weekend rider at 3 rides a week: they learn Uber is $234.00 a month and wins by $516.00 — so they know the car’s fixed costs are the whole story at low mileage, and they check the cost per ride ($34.62 for the car, $18.00 for Uber) before buying a car for the weekend.
Accuracy & limitations
The math is exact for the numbers you enter: Uber monthly = rides × fare × 52 / 12, Uber yearly = rides × fare × 52, car monthly = payment + insurance + gas + maintenance + parking, car yearly = monthly × 12, and the car-equivalent cost per ride = car monthly / (rides × 52 / 12). What the model cannot do is know your real driving: check the fare, because surge pricing can double it, and check the car costs, because a repair can add hundreds in a month. It assumes the car is driven ONLY for these rides, the fare is the average including tip, and the monthly car costs are steady averages. It leaves out the car’s purchase price beyond the payment, depreciation, registration, and the value of your time — and it leaves out wait times, surge pricing, and the freedom of having a car in the driveway.
