At age 35, you have $50,000 in current savings and are contributing $100 monthly toward retirement. If you retire at 70, you'll have 35 years of growth ahead of you.
With an average annual return of 5%, your projected total savings at retirement come to $384,185.14. However, your desired annual income is $100,000 — a target that may be harder to reach than you think.
Using the standard 4% withdrawal rule, your savings would generate only $15,367.41 per year, leaving an income gap of $84,632.59. Based on this scenario, you are not on track to meet your retirement income goal.

Your retirement savings projection of $384,185.14 assumes you continue to contribute $100 each month and earn a 5% annual return for 35 years. While that sum might seem substantial, it translates to a sustainable annual withdrawal of just $15,367.41 when using the widely recommended 4% rule.
This means your retirement savings would cover only about 15% of your desired $100,000 annual income. The shortfall of $84,632.59 every year will require significant adjustments — either by increasing your savings rate, seeking higher returns, reducing your income goal, or delaying retirement.
Without changes, you risk outliving your savings or experiencing a much lower standard of living than planned.

If you were to increase your monthly contribution to $500 instead of $100, your retirement savings would grow to approximately $770,000 — more than doubling your nest egg. That would provide $30,800 per year under the 4% rule, still falling short of $100,000 but narrowing the gap significantly.
Alternatively, delaying retirement by just 5 years (to age 75) would give your savings an extra 5 years to compound. With the same $100 monthly contribution, you'd reach about $477,000, raising sustainable income to $19,000. A more aggressive return assumption of 7% would push your total past $700,000, yielding $28,000 annually. None of these single changes close the entire gap, but combining them — higher savings, longer time horizon, and better returns — can get you much closer to your goal.
The 4% rule states that you can withdraw 4% of your retirement savings in the first year of retirement and adjust for inflation each year, with a high probability that your savings will last at least 30 years. In your scenario, 4% of $384,185.14 is $15,367.41 — meaning you can safely withdraw only about $1,280 per month without depleting your nest egg too quickly.
That depends entirely on your expenses. If your annual spending is under $15,000, $384K might be sufficient. But with a desired income of $100,000, it is not enough. You would need about $2.5 million to support $100,000 in withdrawals under the 4% rule. Your current plan would require drastic lifestyle changes or additional income streams after retirement.
Closing the gap requires a combination of approaches: increasing your monthly savings rate (even to $500/month helps), earning a higher average return (e.g., investing more in stocks), reducing your desired income to a more realistic level, working longer, or using strategies like Roth conversions, part-time work in retirement, or reducing expenses. Our retirement calculator shows that small changes early can compound into huge differences.
A Roth IRA offers tax-free withdrawals in retirement, which can be valuable if you expect to be in a higher tax bracket later. A traditional IRA gives you a tax deduction now but taxes on withdrawals. Given your relatively low monthly contribution of $100, a Roth might be a good choice since you're likely in a lower tax bracket now. But both accounts have the same contribution limits, and you can even split contributions. The key is to start saving consistently, regardless of account type.
