From what you've said the employer contribution is up to a maximum of 6% of salary (€40,000 x 6% = €2400 divided by 12 = €200 per month).Is the employer contribution capped at €200? I thought it might be more and related to whatever contribution she makes
It makes sound financial sense to trigger the maximum employer contribution by the employee contributing 6% herself.
6% is low enough in this day and age - The employer pension contribution is part of her benefits package like salary, health insurance etc. Something to consider when next in negotiation with an employer. Ten % is more common I think and even higher as your grade increases.
