What is the fastest way to save money on monthly expenses?

Audit your three biggest variable expenses: energy bills, transportation, and subscriptions. Switching to LED bulbs saves $100–$200/year. Driving vs. Uber math often favors owning a car for commuters doing 15+ miles/day. Cutting unused subscriptions saves the average American $329/year.

Is it cheaper to drive or take Uber for a daily commute?

For commutes over 15 miles each way, driving is almost always cheaper than Uber — the per-mile cost of owning a car ($0.50–$0.70/mile) is significantly lower than Uber ($1.50–$2.50/mile). For short trips under 5 miles or when parking is expensive, Uber can be cheaper on a per-trip basis.

How much does running an AC unit cost per hour?

A central AC unit costs $0.25–$0.75 per hour to run, depending on unit size and local electricity rates. A standard 2.5-ton unit at $0.14/kWh costs roughly $0.50/hour. Running it 8 hours/day adds $120–$180/month to your bill in summer.

Does driving further for cheap gas save money?

Usually not. If gas is $0.10/gallon cheaper 5 miles away, and your car gets 30 MPG, you spend roughly $0.017 in extra gas per mile driven. A 10-mile round trip costs $0.17 in gas just to get there. You need to buy 1.7+ gallons just to break even — so it only makes sense for large fill-ups (15+ gallons).

How much does a commute actually cost per year?

The true cost of commuting includes gas or transit, vehicle wear ($0.06–$0.10/mile), parking, and lost time. A 30-minute each-way car commute of 20 miles costs the average American $3,000–$6,000/year in direct expenses. Adding lost time valued at minimum wage pushes the true cost to $8,000–$12,000/year.

Are LED bulbs really worth switching to?

Yes. A LED bulb uses 8–10 watts vs. 60 watts for an incandescent. At $0.14/kWh and 3 hours/day use, a single bulb saves $8–$10/year. Replacing 20 bulbs saves $160–$200/year. LEDs also last 15,000–25,000 hours vs. 1,000 hours for incandescents, so you save on replacement costs too.
