What return rate should I assume?

A common long-term planning range is 5%–8% per year depending on your asset mix. Using a conservative rate can help avoid overly optimistic projections.

How does employer match affect retirement savings?

Employer match can materially increase contributions without increasing your take-home cost. Over long time horizons, the match can compound into a large portion of your ending balance.

Should I account for inflation in retirement projections?

Yes. Inflation reduces buying power over time. You can model real returns by subtracting expected inflation from your expected investment return.

How often should I update my retirement plan?

Revisit your plan at least annually or after major life changes. Updating salary, contributions, and return assumptions keeps projections realistic.
