(NewsNation) — Like most financial matters, the ideal 401(k) contribution amount varies from person-to-person depending on their saving goals. A 401(k) is one of the most common employer-sponsored retirement accounts. Offered to full-time employees, it allows workers to allocate a percentage o f their paycheck to a retirement account. Some employers will match employee contributions past a certain percentage threshold — a good starting goal for those uncertain of how much to contribute.

While there's no perfect contribution amount, the general rule of thumb is to contribute 15% of your pre-tax income. That's because most people need anywhere from 55% to 80% of their pre-retirement income for post-retirement living, according to data from Fidelity.

If you know you'll have other post-retirement sources of income — like a pension — you can likely get away with saving less of your income, though it depends on your financial position and decision-making. What is the 401(k) contribution limit? While it is great to contribute as much as possible to your retirement account, there are some finite limits to keep in mind. The maximum 401(k) contribution for 2025 is $23,500. Age can affect that number, with people 50+ able to contribute another $7,500 as a "catch-up contribution," according to NerdWallet. The catch-up contribution limit increases further for those 60 to 63 years old, ringing in at $11,250.
