Raises Are the Easiest Time to Save More

Raises are an opportunity to increase savings rate with minimal lifestyle friction. Small contribution step-ups after pay growth compound meaningfully over time.

A pay increase is one of the few moments when you can boost retirement saving before new spending fully absorbs the money. If you wait too long, the raise starts feeling spoken for.

Decide the Split Before the Raise Becomes Routine

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 what happens if you send part of the raise to your 401(k) and keep the rest in your checking account. Even a modest increase can improve the projection without making day-to-day cash flow feel pinched.

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