What Percentage of Your Pay Should Go to a 401(k)?

Start With the Match, Then Build From There

Percentage-based contributions are scalable and easier to maintain as income changes. The key is choosing a rate that is meaningful and durable.

There is no magic percentage that fits everyone. A workable rate depends on your budget, other priorities, and how aggressively you need to save to close the gap between today and retirement.

Pick a Rate You Can Defend Month After Month

Start with your current salary, balance, contribution rate, employer match, and expected retirement age. Then compare at least two versions of the same plan instead of trusting a single projection.

Model a few contribution percentages and compare how each one changes the projected outcome. The best rate is usually the highest one that still feels stable enough to keep through ordinary, imperfect years.

Use the calculator to pressure-test the choice, then confirm any plan-specific details in your employer documents when those details affect the outcome.
