Utilities are largely a fixed cost that depend on where you live, not a percentage of income. It's not like you should say "I'm rich, I should leave the air conditioner on with the doors and windows open."
It would be more realistic to contact your local utilities for an "average" bill amount (or, even better, an actual historical average for the specific house/apartment you're considering) and budget based on that, instead of trying to figure out how much it "should" be based on what you make.
Investopedia advises that the principal, interest, taxes and insurance should not exceed 28% of your gross income.
The general rule is you should spend no more than half of your income on rent. The better you are doing financially, the smaller percentage of income goes towards your house/apartment.
Not more than 30% I'd say.
less than 20% less than 20%
At least 20% should go towards transportation. At most 30%.

Most small businesses should allocate between 2 and 3 percent of revenue for advertising. That number should increase as the business grows.
The landlord pays tenant utilities. The full service gross (FSG) rental rate includes a set amount that should be allocated towards the payment of utilities, but ultimately it is up to the landlord to pay any and all utilities.
3% is rule of thumb for typical restaurants.
Each state and organization will have its own criteria, from a fixed amount to a percentage of income. Percentage of income usually is between 25-30%.
