Retirement planning at age 40

Many households hit peak expenses in their 40s, which can make saving harder — but you still have decades of growth ahead. If projections show a shortfall, the fastest levers are usually higher contributions, a later retirement date, or adjusting expected spending.

Catch-up mindset

Closing a gap is rarely “all or nothing.” Step-up contributions (raising savings each year) and tax-aware return assumptions can make progress feel more achievable than a single giant monthly number.
