Your starting point: $500,000 in savings at age 50. Over the next 12 years, adding $500 per month and earning an average 4% annual return grows your portfolio to $890,671 by age 62. This projection assumes contributions are made at the beginning of each month and returns compound without taxes or fees.

Using the 4% withdrawal rule — a common guideline for sustainable retirement income — your savings could produce $35,626.84 per year (4% of $890,670.94). Your desired income is $30,000, so you have a surplus of $5,626.84. This positive gap means you are overfunded, giving you flexibility to spend more, save for health care, or leave a legacy.

However, keep in mind that this estimate relies on consistent returns and ignores inflation, taxes, and market volatility. The ‘on track’ signal is encouraging but should be stress‑tested with different assumptions.

If you continued working until age 65 instead of 62, you would add three more years of contributions and growth. Assuming the same $500 monthly contributions and 4% return, your savings would grow to about $1,002,000, providing a sustainable income of $40,080 — well above your $30,000 goal. The downside is delaying retirement and possibly missing out on years of leisure.

Alternatively, if you increased your monthly contributions to $1,000, retiring at 62 would yield around $954,000, generating $38,160 per year. That extra safety margin could help weather market downturns or cover unexpected health costs. Conversely, if returns drop to 3%, your nest egg shrinks to about $839,000, making your sustainable income roughly $33,560 — still above $30,000 but with a thinner cushion.

1. Stress‑test with lower returns: Run scenarios with 3% or even 2% annual returns to see how your plan holds up under adverse market conditions.
2. Increase contributions if possible: Even $100 more per month can add thousands to your final savings and increase your safety margin.
3. Review asset allocation: With 12 years to go, consider a mix of stocks and bonds that balances growth potential with risk management as retirement nears.
4. Plan for healthcare costs: Medical expenses often rise in retirement; factor in Medicare premiums, deductibles, and potential long‑term care.
5. Evaluate withdrawal strategy: A fixed 4% withdrawal may not be optimal during market fluctuations. Consider a flexible spending rule or bucket strategy.
