The rate slowed to 84.39 percent, according to state statistics agency TUIK, down from 85.51 percent in October.
Turkey's inflation has risen steadily since reaching a low of 16.6 percent in May 2021.
The emerging market's troubled economy has turned into a major stumbling block on Erdogan's path to a third decade in power in a presidential poll due by next June.
Erdogan's approval rating began to suffer when he set off on an unusual economic experiment last year that tried to bring down chronically high consumer prices by lowering borrowing costs.
Conventional economic theory embraced by almost every other big nation pursues the exact opposite approach.
The price of imports such as oil and gas soared, creating an inflationary spiral that the nominally independent central bank fed further by continuing to lower interest rates.
Turkey's lira began to drop in value almost immediately, as consumers rushed to buy up dollars and gold to try and protect their savings.
Erdogan has maintained that his unwavering focus on economic growth at all costs -- achieved through cheap lending and state support -- will eventually pay off.
"We will witness the rapid descent of inflation soon and we will see together that the dirty scenarios built on this trouble are torn and thrown away," he repeated over the weekend.
Erdogan has blamed inflation on outside factors such as the global spike in food and energy prices caused by Russia's invasion of Ukraine.
- Election strategy –Erdogan's much-criticised economic team hailed Monday's announcement as vindication of their approach.
"As we have previously stated in various media, we have entered a downward trend in inflation, leaving the peak behind, unless there is an unexpected global development," Finance Minister Nureddin Nebati tweeted.
Most economists believe that Turkey's inflation rate will continue to slow but remain elevated for many months to come, unless Erdogan radically changes his approach.
An accompanying inflow of funding from the Kremlin and Turkey's former rivals in the Middle East, which Erdogan secured through a major diplomatic reversal this year, will help the government prop up the lira, economists believe.
Erdogan's strategy aims at "keeping the lira relatively strong this side of elections with foreign money", Timothy Ash of BlueBay Asset Management said in a tweet.
"But that will destroy competitiveness with massive real appreciation."
Yet many also question Turkey's official statistics, which are produced by an agency whose leader has been replaced by Erdogan twice in the past year.
According to a respected monthly study released by independent economists from Turkey's ENAG research institute, the annual rate of consumer price increases reached 170.70 percent in November.
A separate poll earlier this year showed the overwhelming major of Turks believing the ENAG figures over ones released by the government.
