Then you should be looking at a 15-30% reduction in the median salary for your job. So if it is 100k you should be looking at 70K with 30%. It differs from company to company, but that is my golden rule that I go by.
As the company becomes more and more profitable after X rounds naturally the equity reduces for new hires and the rate increases. So with the above example, if you gave your second level hires 10% it should be in the range of a 20% reduction from the median wage. By the time you are at 1-2% equity rounds of hiring. You should be close to or above market and the equity is more of a leverage tool to get and retain top talent.
