How to add custom charges (fee) to item row total into cart for magento 2?

[Dmitry_Fedyuk]

You can implement it as a custom checkout.cart.totals handler: https://mage2.pro/t/1070

Or you can just set it up as a tax:

Thanks for your answer.

Actually I need code to increase row total of item through pro-grammatically after event of add to cart. e.g. If product A has price $14 Then I need row total as $14(Price) + $2(Fee) = $16(Row Total of item).

Item	Price	Qty	Subtotal
LifeLong Fitness IV	$14.00 + $2(fee)	1	$16.00

Hi,

Overwrite Magento\Quote\Model\Quote\Item class calcRowTotal() method and set $this->setCalculationPrice($total);

That's it.
