200 * 300 *15 = 900,000 yuan.

190 * 320 * 20 =1216000 yuan.

The overall impact is that the actual material cost is 3.65438+0.6 million yuan higher than the planned cost.

According to the actual material consumption, the affected material cost is190 * (320-300) *15 = 57,000 yuan.

The unit consumption of materials increased by 20kg (320-300), and the total planned cost increased by 57,000 yuan;

According to the actual material unit price, the affected material cost is190 * 320 * (20-15) = 304,000 yuan.
