Retirement Calculator: Are You On Track? The Honest Answer.

Most retirement calculators have an optimism problem. They use aggressive return assumptions, ignore fees, skip inflation adjustment, and produce a number that feels reassuring rather than accurate.

Here's a more honest framework.

The Four Numbers That Determine Your Retirement

1. Current savings balance — what you have right now in all retirement-oriented accounts.

2. Annual contribution — what you're putting in each year, including employer match.

3. Years until retirement — the time variable that matters most.

4. Withdrawal rate — how much you plan to take out each year in retirement, as a percentage of your portfolio.

The 4% rule (withdraw 4% of your portfolio annually, adjusted for inflation each year) has held up well historically. It implies you need 25x your annual retirement spending saved.

The Math Most People Avoid

If you need $60,000/year in retirement: you need $1.5 million saved (25x).

If you need $80,000/year: you need $2 million.

If you need $100,000/year: you need $2.5 million.

Social Security reduces these targets — the average benefit is ~$1,800/month ($21,600/year), which reduces your portfolio requirement by ~$540,000 at the 4% rule.

What Actually Moves the Needle

Increasing your contribution rate by 3-5% has dramatically more impact than chasing higher returns. Working 2-3 additional years — especially if those are high-earning years with no mortgage and no kids at home — can add $300,000-500,000 to your final balance between the additional contributions and the compressed withdrawal window.
