The price you negotiate for a car and the interest on your car loan are only part of the cost of owning a new vehicle. Depreciation, taxes and fees, and what you pay over the years for insurance, fuel, maintenance and repairs are all important ingredients in the long-term cost of ownership.

Even the opportunity cost of out-of-pocket expenses (what you'd make by investing the money elsewhere) is part of the overall tally.

To find the cheapest cars to own and operate, we asked Vincentric, an automotive data firm, for a list of 2013 vehicles with the lowest five-year ownership costs. Because small cars tend to have the lowest market price, the best fuel economy and reasonable insurance rates, all the vehicles on our list are either compacts or subcompacts.

All of the vehicles listed here also have manual transmissions, unless otherwise noted (they tend to be more fuel-efficient than automatic). But most of our picks include a CD player and auxiliary inputs for music as standard features. Also, thanks to federal mandates that went into effect for the 2012 model year, stability control is now standard for all vehicles. Other safety features have also gotten better: All of these cars have at least six airbags, anti-lock brakes and traction control.

The market price is the average transaction cost and reflects consumer rebates. Fuel costs are based on $3.23 a gallon for regular gasoline and 15,000 miles a year of mixed city and highway driving. The ownership cost assumes you are paying 2.76% interest on a five-year loan but that you can recoup the cost of the car, minus depreciation, when you sell the vehicle after five years.

As one of the nation's top sellers, the Corolla has a loyal fan base. Low ownership costs, decent power and fuel economy, and safety (the Insurance Institute for Highway Safety (IIHS) rates it a Top Safety Pick) add to the allure.

Competing with a compact stalwart like the Toyota Corolla isn't easy, but the Kia Forte is proving it's a player in its own right. Lower out-of-pocket costs are a key ingredient, but it also bests Corolla on power (156 horsepower, versus 132 hp for the Corolla) while offering similar fuel economy. Plus, USB and Bluetooth are standard, and it's an IIHS Top Safety Pick.

Other costs: insurance over five years, $4,643; financing 5-year loan at 2.76%, based on a market price of $15,166 and a 15% down payment, $877; depreciation, $9,704; fees & taxes, $1,187; opportunity cost of down payment and other out-of-pocket costs, $367; maintenance, $2,133; repairs, $1,193

Ford's subcompact sedan is a well-rounded entry, from its sporty styling inside and out to its peppy 1.6-liter engine. The Fiesta is also an IIHS Top Safety Pick. A knee airbag for the driver comes standard, but you'll pay $495 for a CD player and keyless entry on the base model.

Other costs: insurance over five years, $5,624; financing 5-year loan at 2.76%, based on a market price of $13,615 and a 15% down payment, $782; depreciation, $9,043; fees & taxes, $1,080; opportunity cost of down payment and other out-of-pocket costs, $360; maintenance, $1,349; repairs, $3,120

The world's smallest four-seater, the Scion iQ packs value into a tiny package that measures just 10 feet from bumper to bumper (the Mini Cooper Hardtop is 12 feet).

An automatic transmission, keyless entry, steering wheel audio controls and 11 airbags are standard.

Redesigned for 2012, the Rio has sporty styling and plenty of power.
