Business Owner Retirement Readiness Calculator 2026

Are you on track to retire from your business? Generic retirement calculators miss the factors that matter most for self-employed owners: business equity at sale, irregular contribution history, and multiple asset pools. This tool combines all of them into one projection.

How to read your results

This calculator projects three things: how your current retirement accounts grow with additional contributions, how your taxable savings grow, and — optionally — how much you'd net from selling your business. At retirement, it applies the 4% safe withdrawal rate (the rule of thumb from the Trinity Study: a 4% annual withdrawal from a diversified portfolio has historically survived 30-year retirements with high probability), then adds Social Security income, and compares the total against your spending target.

What the calculator does not model: inflation (use a real return rate of 3–5% if you want inflation-adjusted results), taxes on pre-tax account withdrawals (traditional 401k and IRA distributions will be taxed as ordinary income in retirement), sequence-of-returns risk, or required minimum distributions. A financial advisor can run a full tax-adjusted Monte Carlo projection specific to your situation.

Business owners: your business is often your largest — and hardest to value — asset. Service businesses typically sell for 1–3× annual seller's discretionary earnings (SDE). Tech-enabled or recurring-revenue businesses can reach 4–8×. These are rough rules of thumb. Before making retirement decisions based on a business equity number, get a formal valuation from a business broker or M&A advisor.

The four retirement income sources business owners have

1. Retirement accounts

Solo 401(k), SEP IRA, cash balance plan, Roth IRA. Self-employed owners can contribute up to $72,000/year tax-deferred in 2026. Most owners are under-contributing significantly — see which plan fits you.

2. Taxable savings & investments

Brokerage accounts, savings, and other investments outside retirement plans. More flexible than retirement accounts (no penalties or RMDs), but no upfront tax shelter and subject to capital gains tax on growth.

3. Business equity

Proceeds from selling the business at retirement. Often the largest number on paper — but timing, valuation multiples, buyer availability, and deal structure determine how much you actually net. See the full tax planning guide.

4. Social Security

Self-employed owners pay both sides of FICA (15.3% SE tax) but receive the same benefit credits as W-2 employees. WEP and GPO were repealed in January 2025 — owners with public-sector work history may see higher-than-expected benefits. Get your personalized estimate at ssa.gov/myaccount.

Common retirement gaps business owners discover

Under-saving during high-income years. A business owner netting $400K can contribute up to $72,000/year to a solo 401(k) — or $150,000–$280,000/year combined with a stacked cash balance plan. Many owners contribute $15,000–$25,000 and miss $50,000–$130,000 in annual tax-deferred savings. That $100K annual gap, compounded at 6% for 15 years, exceeds $2.3M. See cash balance plan stacking.
No retirement plan at all. Self-employed owners often defer setup because "I'll do it next year." A solo 401(k) must be established by December 31 to make employee deferrals for that year. A SEP IRA can be opened and funded up to the tax-filing deadline (including October extensions). If you have no plan yet, this is the highest-priority financial action you can take.

Business-heavy, portfolio-light — and no backstop. Many owners have $800K–$2M in business equity but under $300K in retirement accounts, creating dangerous concentration risk. If the business doesn't sell for the hoped-for multiple — or can't be sold at all — there's no fallback. Building both streams (business equity and investable assets in parallel) is the discipline that separates owners who retire on their terms from those who can't.
Not accounting for tax on the business sale. A $1.5M gross sale price doesn't produce $1.5M to retire on. At a blended rate of 25–30% (capital gains + depreciation recapture + broker fees), the actual net is closer to $1.05–$1.1M. The structure of the deal — asset vs. stock sale, installment election, personal goodwill allocation, QSBS eligibility — can move that number by $200K+. See selling your business: tax planning guide.

If your projection shows a gap: three levers to pull

  1. Increase annual contributions. For owners earning $200K+, this is the single highest-leverage action available. Adding a cash balance plan on top of a solo 401(k) can add $100,000–$300,000/year in tax-deferred savings and deductions. Every dollar contributed now removes roughly $3–$5 in future retirement gap, depending on years remaining. See the retirement plan selector.
  2. Extend the timeline. Working 2–3 additional years has compounding benefits: more contributions, more growth years, a shorter drawdown period, and higher Social Security credits. Try adjusting the target retirement age slider — for most owners, 2 extra years makes a larger difference than any other single change.
  3. Reduce the spending target. Retiring on $100K/year instead of $150K/year cuts the required portfolio from ~$2.5M to ~$1.7M at a 4% withdrawal rate — an $800K reduction in the savings hurdle. The right number is often lower than owners expect once the business overhead (employees, insurance, facilities) and commute expenses disappear.

A financial advisor who specializes in small-business owners can run detailed projections with tax-adjusted withdrawal modeling, Monte Carlo simulations, RMD scheduling, and a specific business-sale scenario layered in — and help you identify which combination of levers applies to your situation.
