That is a 10.25 per cent increase from the previous salary of £12,117.24, which representatives received in the financial year up to April 2019. That is the last comparable year as the financial year ending April 2020 included the election, with changes in councillors.
Councillors who hold key roles on committees receive special allowances.
The city's highest-paid councillor is Green Party leader Phelim Mac Cafferty, who earned £40,258.
He is the current leader of Brighton and Hove City Council.
Ex-Labour leader Nancy Platts was the second most paid, earning £32,088.
She also served as leader of the city council during the period.
A council spokesman said: “Councillors do not set their own allowances. They are recommended by an independent body called the Independent Renumeration Panel.
