Why the standard advice fails owners
Percent-of-salary rules assume a salary. Owners set their own compensation for tax reasons, reinvest most profits, and quietly assume the company's eventual sale will fund retirement. Sometimes it does. But a business is a concentrated, illiquid asset with a price nobody quotes daily — and "my business is my retirement plan" is a forecast, not a plan. The honest starting point is to build the number from spending, not from income.
Start from the retirement you intend to fund
Write down what a year of the retirement you actually want costs in today's dollars — housing, healthcare before and after Medicare, travel, family support. Multiply by 25–30 for a first approximation of the portfolio that supports it, then refine with real modeling that accounts for Social Security timing, taxes on withdrawals, and inflation. A household that spends $200,000 a year needs roughly $5–6 million of income-producing assets — outside the business — or a credible, discounted plan for converting business value into that portfolio. A written retirement income plan turns this arithmetic into a funding schedule.
Discount the business — hard
Whatever you believe the company is worth, the retirement math should use a fraction of it. Private sales carry marketability discounts, earn-outs that may not pay, taxes on the gain, and timing risk — the best year to sell is rarely the year you want to retire. A useful discipline: count no more than half of a conservative valuation, after tax, toward the retirement target. If the sale delivers more, wonderful; the plan never depended on it.
Close the gap with plan design
The gap between the target and the discounted business value is what the savings plan must close — and owners have better tools than any employee:
- Solo 401(k) — for owner-only businesses: employee deferral plus employer profit sharing, with Roth options, often reaching the low-to-mid five figures at moderate income levels.
- Safe-harbor 401(k) with profit sharing — the workhorse once you have staff: owners defer the maximum without discrimination-testing failures, and profit sharing flexes with the year's cash flow.
- Cash balance plan — layered on the 401(k) in your peak-earning decade, it can shelter six figures a year, with contributions that rise with age. It is a multi-year commitment that demands steady cash flow — powerful, not casual.
- Taxable investing and HSAs — the unglamorous layer that provides pre-59½ flexibility and fills years the qualified plans can't.
Current contribution limits change annually — the IRS publishes them at its retirement plans reference — and the right structure depends on payroll and demographics, which is why we design these jointly with the CPAs. The comparison is laid out on our business-owner page.
A sequence that works in practice
First, fund the household's liquidity policy — cash outside the company. Second, capture the cheapest tax wins: HSA, then the qualified plan sized to this year's cash flow. Third, automate a taxable investing draw from distributions so diversification happens on schedule. Fourth, revisit the design every year — plan limits, payroll, and profits all move, and last year's right answer rarely repeats. The consistent owners we see aren't the ones who saved heroically in one great year; they're the ones whose plan survived the mediocre ones.
Two owners, same income, different math
Consider two owners, each drawing $300,000 from companies of similar size. The first counts the business at full asking price, saves loosely in a SEP when cash allows, and holds the rest in the company. The second runs the discipline above: household spending mapped, business counted at half a conservative valuation after tax, a safe-harbor 401(k) with profit sharing capturing the deduction every year, and an automated taxable draw from distributions. Ten years on, the second owner's retirement no longer depends on the sale at all — the sale has become upside. Same income, same industry; the difference is entirely structural, which is the point: the inputs you control are savings rate, plan design, and time, not the multiple a buyer eventually pays.
The mistakes that cost the most
- Counting the business twice — as both the retirement fund and the income that was supposed to build one.
- Letting plan design lag the company — still running a bare SEP years after payroll and profits could justify a 401(k)/cash-balance stack.
- Skipping the taxable layer — then facing a retirement at 58 with everything locked behind 59½ penalties.
- Ignoring Social Security — owner compensation strategy changes covered earnings; the benefit estimate at ssa.gov deserves an annual look.
When to start counting
Ten years from your intended date, the plan should exist on paper. Five years out, the savings gap should be closing on schedule and exit preparation should begin. At two years, Social Security timing, healthcare bridging, and the withdrawal strategy get modeled for real. The single most expensive answer to "how much should I save?" is the one delivered eighteen months before retirement, when the calendar has run out of room to compound.
Before you act: model the expected benefit, the deadline, the documentation required, and the effect on cash. Tax and retirement rules are fact-specific and change every year — confirm any strategy for the current year with your advisor and CPA before implementing it.
