What is the best word to describe the “optimal” price in USP?

Question

Marketing

In the USP, I would like to note the low price in relation to other solutions.

Problems:
1) Competitors in this market have very different payment models. Someone SaaS with $ per subscription, someone at a fixed price, someone even offers development services. To become attached to "at a price below competitors" is difficult.
2) The cost is too high (from ~10k to 30k) to make everyday comparisons like "at the cost of 2.5 cups of coffee"

Can I just mark it in any way, leaving the abstract "smart / optimal / best price"? Or are there options?

An example of a raw, slightly abstract (for example) USP:

Start your own business this week at the best price

PS Or is it better to directly write the price, because the consumer will see for himself that it is optimal within the framework of his expectations?
I.e:

Start your own business this week at a price of 10,000 rubles

PSS The USP will be placed in the advertised ad.

Answer 1

Market, Pricing, and Fair Price
PS smart/best price is bullshit and abstraction. And there is a third option: just humanly describe how your product helps the client, with examples.
+ It is not clear where exactly and in what context of the USP?

Answer 2

We must probably still understand that in such cases they do not choose at a price))
