Trump's proposed tariffs would cost Americans $500 billion a year, think tank says

• Trump's proposed tariffs could cost Americans $500 billion annually, a think tank estimated.
• The cost of tariffs is often passed onto consumers as producers raise prices.
• A 10% tariff on imports could cost households an extra $1,500 a year, researchers say.

Donald Trump has touted plans to impose tariffs on imports in his campaign for a second presidential term, but those proposals could end up costing Americans half a trillion dollars a year, according to estimates from a Washington DC-based think-tank.
