Average 401k Balance Jumps 10.5 Percent in Second Quarter of 2026 to Record High

Fidelity Investments reported that average 401k, 403b, and IRA balances reached record highs in the second quarter of 2026, with 401k balances posting a 10.5 percent gain from the previous quarter.

That quarterly increase was the strongest since late 2020, according to Fidelity's data. The gains were driven by a combination of rising stock prices and consistent employee contributions throughout the quarter.

The record highs come despite ongoing concerns about the national debt, inflation, and interest rates. For many workers, the second quarter results offered a welcome sign that their retirement savings are growing.

Financial advisors say the data underscores the value of staying invested through market volatility rather than pulling money out during downturns. Workers who remained in their plans through earlier periods of market turbulence in 2026 benefited from the rebound.

Fidelity manages retirement accounts for millions of Americans and releases quarterly data on account balances and contribution rates. The company noted that the percentage of workers contributing to their 401k plans remained stable, with many taking advantage of automatic enrollment features.

For workers approaching retirement, the record balances are encouraging, but advisors caution that market conditions can change quickly. They recommend reviewing asset allocations regularly and making sure the mix of stocks and bonds matches your timeline and risk tolerance.

For younger workers, the data reinforces the case for starting contributions early. Even small amounts invested consistently over decades can grow significantly through compound returns.

The IRS increased 401k contribution limits for 2026, allowing workers under 50 to contribute up to $23,500 annually, with those 50 and older able to contribute up to $31,000.
