Toyota today boosted its full-year profit forecast by 12.4% while also lifting its revenue estimate, citing a weak yen and cost cuts. 

The world's biggest car maker revised up its fiscal year net profit forecast to 2 trillion yen ($17.5 billion) from an earlier 1.78 trillion yen.

It also said full-year revenue would come in at 26.5 trillion yen, from a previous 25.7 trillion yen. 

The upgraded forecasts came as Toyota booked a 1.13 trillion yen net profit for the six months to September, up from a trillion yen a year ago.
