We cap your planned employee deferral at the lesser of 100% of compensation and the SIMPLE salary reduction limit for the selected tax year (plus catch-up if you indicate age 50 or older). We then compute an employer contribution: either 2% of compensation (nonelective) or a 3% match equal to the lesser of your allowed deferral and 3% of compensation. The total is employee plus employer for this single-participant illustration.
Allowed deferral = min(planned, SIMPLE cap + catch-up?, compensation)Match (3% mode) = min(allowed deferral, 3% × compensation)Nonelective (2% mode) = 2% × compensationMulti-employee plans, reduced match elections, and self-employed compensation require your plan’s exact rules.
SEP and solo 401(k) use different mechanics—see related tools below
If your employer uses 2% nonelective instead, employer dollars may differ from the match scenario—select the mode that matches your annual SIMPLE notice.
