Interpreting Results
Start with Annual employer match. Then compare Needed for full match and Missed annual match before deciding what changes the answer most.
Input Steps
Field by field
- 1
Salary
Enter salary, current contribution rate, employer match percent, employer match limit, expected return, and years remaining. The key decision is identifying the minimum employee contribution that captures the full match.
- 2
Employee Contribution Percent
Read annual employer match, the contribution rate needed for the full match, and missed annual match. A full employer match is usually a 50%-100% immediate return on that slice of contribution.
- 3
Employer Match Percent
If you are not capturing the full match, very few other uses of money compete mathematically unless you have high-interest debt. Leaving match dollars unclaimed is effectively taking a pay cut.
- 4
Employer Match Limit Percent
Raise payroll deferral to the full-match threshold first, then decide whether extra dollars should go to debt, an IRA, or taxable investing. Use the retirement calculator to see the long-run impact of the higher contribution rate.
- 5
Annual Return Percent
Re-run when salary changes, the plan formula changes, or you adjust deferrals midyear. Track actual contribution rate, match captured, and any missed dollars.
- 6
Years
Enter years with realistic baseline assumptions before moving to sensitivity checks.
Run one base case and one sensitivity case before trusting a single output.
