Enter your estimated business sale price, desired annual income in retirement, and your timeline. Get an instant estimate of whether your exit funds your retirement — and what strategies close the gap.
The Business Sale to Retirement Calculator estimates how much income you can generate from selling your business and converting proceeds into retirement assets. It combines three inputs: business sale price, desired annual retirement income, and life expectancy. The calculator outputs: (1) how much liquid retirement capital the sale produces after taxes, (2) the annual income that capital can generate at a 4% withdrawal rate, and (3) a comparison of three conversion strategies — commercial SPIA (guaranteed income annuity), dividend stock portfolio, and Treasury bond ladder. The average business sale in the U.S. in 2025 was $1.2M (BizBuySell 2025 Market Report). After 20% capital gains tax, a $1.2M sale nets $960K. At a 4% withdrawal rate, that produces $38,400/year — below the $60,000+ median household income needed in retirement. This tool shows whether your sale price will fund your desired retirement lifestyle, or where the gap is.

This tool estimates whether your business exit can fund your retirement by calculating your after-tax proceeds and comparing them against the income a liquid portfolio can generate. The three inputs — sale price, desired income, and timeline — determine whether you have a gap and which conversion strategy best closes it.
Most business owners selling a profitable operating company face long-term capital gains tax of 20% plus net investment income tax (NIIT) of 3.8% — totaling 23.8% federally. Most states add 5-7%. Plan on retaining 65-75% of your gross sale price after taxes. A $1.2M sale typically nets $780K-$900K depending on your state tax burden.
The 4% rule (Bengen, 1994) is a conservative withdrawal benchmark: divide your desired annual income by 0.04. To generate $80,000/year requires $2M in liquid capital. If your after-tax proceeds fall short, three strategies can close the gap:
| Strategy | Pros | Cons | Best For |
|---|---|---|---|
| SPIA | Guaranteed income, no management | No liquidity, inflation risk | Baseline income needs |
| Bond Ladder | Predictable, Treasury-backed | Low return, rate risk | Conservative investors |
| Index Fund Portfolio | Growth, liquidity, inflation hedge | Market volatility, sequence risk | 10+ year horizon |
Plan on retaining 65-75% of your gross sale price. The federal long-term capital gains rate is 23.8% (20% LTCG + 3.8% NIIT). Most states add 5-7%. If your business is an S-Corp or C-Corp, additional taxes may apply on the corporate level. A tax advisor specializing in business exits typically pays for itself many times over at deal size $500K+.
The 4% rule was derived by William Bengen in 1994 by testing historical portfolio returns across all 30-year periods since 1926. A 4% initial withdrawal rate adjusted for inflation survived every 30-year period tested. In 2026, with elevated valuations and bond yields, some researchers suggest 3.5-3.7% is more conservative for a 30+ year retirement. The calculator uses 4% as a baseline — enter your own expected return if you believe your portfolio will outperform.
A Single Premium Immediate Annuity (SPIA) is an insurance product that converts a lump sum into guaranteed monthly income starting immediately. For business exit proceeds, a SPIA provides a floor income independent of market performance. As of 2026, a $300K SPIA for a 62-year-old generates approximately $1,500-$1,800/month — replacing the income the business sale proceeds would otherwise need to generate through investment returns.
Business brokers typically sell companies 20-40% above owner-direct sales (BizBuySell data). Broker commissions run 8-12% of the transaction value. For a $1.2M sale, a broker might earn $96K-$144K — but the premium they generate often exceeds their fee. Recruiters, M&A advisors, and M&A broker networks serve deals above $1M.

Third-party sale: maximum price, clean exit, taxes owed on capital gains. ESOP: potential tax deferral under Section 1042 (reinvest proceeds in Qualified Replacement Property within 12 months), employee ownership outcome. ESOPs are complex and best for companies with $5M+ in EBITDA. Consult a tax attorney and M&A advisor before choosing a sale structure.
