Changing jobs is one of the best ways workers can increase their pay, and a surprisingly strong job market means they still have opportunities. This is great news for workers, but remember: Make sure you’re putting aside as much in your new 401(k) plan as you did in your old one.

When a worker changes jobs, they must take the extra step of enrolling in their new employer’s 401(k) plan and deciding how much of their salary to contribute. Otherwise, if they are lucky, they will end up being automatically enrolled in the plan and contributing according to the default salary percentage decided by the employer.

In nearly half of the auto-enrollment 401(k) plans for which Vanguard keeps records, this default is 3% or 4%.

For new workers just starting their careers, this type of contribution can make sense, although the general rule of thumb is to save 10 to 15 percent of your salary. Many 401(k) plans will also automatically increase this savings percentage by 1 percentage point per year.
