Your question's scope too wide to discuss, probably will receive many methods but may confuse you further.

I would highlight to you an underlying principle of pricing in the commercial world:
"A price is attached to a product as an effort/ cost the buyer willing to pay to exchange the product. Pricing, on the other hand, is the intention of the seller to attract the buyer to buy the product so that the buyer can be benefited in the way the seller wanted to."

Thus, if you are clear of what you want the buyer to be benefited, you will know what price you want to set (ideally).

Based on the cost + plus or market value approach, you can match with your ideal price to close the gap to make your pricing more reality and competitive at the same time.
