Understanding US 401k Plans
A US 401k is an American employer-sponsored retirement savings plan that allows you to contribute pre-tax income, reducing your current taxable income while building retirement savings.
Many US employers match a percentage of your contributions, essentially providing free money toward your retirement. Always contribute enough to get the full match.
The US IRS sets annual contribution limits. For 2024, you can contribute up to $23,000, or $30,500 if you're 50 or older with catch-up contributions.
Retirement Planning Tips
Start contributing as early as possible. Even small amounts can grow significantly due to compound interest over decades.
Never leave free money on the table. Contribute at least enough to get your full employer match.
Increase your contribution percentage each year, especially after salary increases or bonuses.

Annual Salary Growth: Expected annual salary increases. US average is 2-4%. Higher growth means higher future contributions.
