The government has promised to link pension and benefits rises to inflation.
The growth plan was announced in the mini-budget.
He rejected the idea that it made people worse off.
The Bank of England stepped in to prevent the collapse of some pension funds after the plans were announced.
The plan has been criticized by the International Monetary Fund and the Bank governor.
Mr Kwarteng told reporters on Thursday that he wanted to boost growth and lower energy bills.
He said that the mini budget was essential in reseting the debate around growth.
Without growth you won't be able to generate the income and the tax revenue to pay for the public services that we want to see.
He said that the government's plan to limit energy bills for households and businesses would save people money.
He said it was too early to say if he would follow through on the previous government's promise to increase benefits.
He said the prime minister was committed to reinstating the triple lock on pensions, which means they increase by the highest inflation, average wage rise, or both.
This is the first time that Mr Kwarteng has commented on his mini-budget since Sunday.
The Bank of England was forced to intervene after the pound hit a record low against the dollar. $65 billion of bonds will be bought in order to calm the markets.
The Prime Minister told a number of radio stations that the tax cuts outlined in the mini-Budget were the right plan.
The Treasury turned down an independent forecast of the impact of government's plans on the economy before the mini budget. The market reaction to the plans was worse due to this.
The OBR said on Thursday that it had been asked by Mr Kwarteng to produce a first draft of its next economic forecasts.
