Nationwide has issued an update that could mean a welcome boost of around £436 for millions of savers across the UK. New figures released this week by the world’s largest building society show that people earned an average of £436 in interest on their savings in 2025, as higher interest rates filtered through to bank accounts.

The research, based on a survey of 2,000 adults, also found that Britons are planning to save more in the year ahead, with the average savings target for 2026 set at £7,535. Those aged 25 to 34 are particularly ambitious, aiming to save almost double that amount.

However, the data highlights a clear divide in saving habits. While nearly a third of adults (32%) say they plan to save more than they did last year, and 43% expect to save the same amount, one in ten (10%) admit they do not expect to save anything at all.

Despite the £436 average interest figure, not everyone benefited.

Nationwide found that 13% of people earned no interest whatsoever in 2025, often because their money was left sitting in current accounts paying little or nothing.

Richard Stocker, head of savings at Nationwide, said the findings were encouraging but warned many people were still missing out.

“It’s encouraging that most people aim to save in 2026, with many planning to put away more next year,” he said.

“However, too many are missing out on interest by leaving money in current accounts.

“Our advice is simple: start early and save regularly to build a habit. Make use of helpful tools such as the budget calculator on our app and benefit from incentives such as our £175 bank account switching offer, which can be a great way to kick-start a savings habit.”

With interest rates remaining relatively high, Nationwide says ensuring savings are in the right account could make a significant difference, potentially turning spare cash into hundreds of pounds landing in bank accounts each year.
