Starting retirement planning at age 45 is a common reality for many. For this scenario, you have 25 years until age 70, you currently have $0 saved, and you can commit $1,000 each month into a retirement account earning a 7% annual return. Your target? A desired retirement income of $100,000 per year. Let's break down the math and see where you stand.
Plan your retirement savings with projections, withdrawal strategies, and goal tracking.

Optimistic (3% higher)

At 10.0% return
After 25 years of disciplined monthly contributions of $1,000 at a 7% annual return, your projected retirement savings grow to $758,988.45. This is impressive, but when you apply the widely used 4% sustainable withdrawal rule, that nest egg only generates about $30,359.54 per year in retirement income. That's far below your desired $100,000 – leaving an income gap of $69,640.46.
The calculator shows you are currently not on track to meet your income goal. The long time horizon (25 years) and decent return help, but the combination of starting late and a high desired income makes this a challenging scenario. While $758,988 is a solid base, it's only enough to cover roughly 30% of your target annual income.

Compare this to someone who started at age 35 with $0, same $1,000 monthly and 7% return, retiring at 70 (35 years). Their savings would be about $1.7 million – still short of $2.5 million for $100k income, but with a sustainable income around $68,000, cutting the gap to $32,000. Alternatively, if this 45-year-old increased monthly contributions to $2,500, the savings jump to ~$1.9 million, yielding ~$76,000 income – still below $100k but far better.
Another comparison: if you could delay retirement to age 75 (30 years saving), the same $1,000 monthly grows to about $1.13 million, yielding $45,000 income – cutting the gap to $55,000. Or if you reduce desired income to $50,000, the current $30,359 covers 61%, making the gap manageable with Social Security or part-time work. The key takeaway: with a 25-year horizon, you need either much higher contributions or a lower income goal to close the gap.
The 4% rule assumes you withdraw 4% of your savings in the first year of retirement and adjust for inflation each year. On $758,988, 4% equals $30,359.54. This rate historically allows your money to last 30 years even in poor market conditions. The $758k is not your annual income – it's the total nest egg. To get $100,000 sustainably, you'd need roughly $2.5 million saved.
Social Security benefits are modest. At age 70, your full benefit might be around $3,000-$4,000 per month ($36,000-$48,000 annually) if you've had a solid work history. That could cover part of the gap, but not all. Combined with your $30,359 from savings, you'd reach about $66,000-$78,000 – still below $100,000. Plus, Social Security faces potential cuts, so don't rely on it fully.
Yes, 7% after inflation is a common long-term average for a balanced portfolio (e.g., 60% stocks/40% bonds). Over 25 years, you'll likely experience market ups and downs, but 7% is a reasonable planning assumption. If you invest more aggressively (80%+ stocks), you might aim for 8-9%, but expect higher volatility. A financial advisor can help tailor your asset allocation to your risk tolerance.
Not hopeless, but challenging. You're currently not on track, but with adjustments you can improve. Option 1: Save more – $2,500/month gets you to $1.9 million. Option 2: Retire later – even 5 more years (age 75) boosts savings to $1.13 million. Option 3: Lower your income goal to $60,000. Many people mix strategies: higher savings, later retirement, and part-time work in retirement. Every positive change helps close the gap.
