there is no so-called charging standard or standard price for designing LOGO, but only a rough guide price at most. Upgrading the old LOGO is not necessarily cheaper than redesigning a LOGO. If you want a good design, don't care about spending a little more money. There will never be a better design at a very low price, and it is impossible for a truly qualified designer to sell his labor cheaply and devalue the artistic value of his works.
I think it makes sense to copy a piece of other people's content, and I hope it will be useful to you:
If you invite a master designer to design a logo, it will generally cost 411-1 million yuan;
If you give it to a well-known big design company in Beijing to design the logo, the price is generally between 51,111 and 211,111;
Beijing's well-known small and medium-sized formal professional design companies or studios, the design logo price is generally 81-51,111 yuan. There are also many cost-effective design companies. In fact, the quality you get will not be worse than that of large companies that specialize in high-end brand routes, because all the designers who provide design services are excellent designers who graduated from prestigious schools;
Ordinary small design companies or studios generally charge 2,111-4,111 yuan. Of course, there are many lower-priced ones, so we don't comment on the quality. If you are purely considering the budget, you can also choose the kind of several hundred yuan.
