Business Sale Price to Retire: A Backward Test for Owners in Their Early 50s With an Offer

When the price in your head came from someone else's letter

Latoya, a hypothetical 51-year-old, divorced, owns a wholesale bakery that supplies regional grocery stores. A competitor's letter of intent offers $3.2 million, with 30 percent paid as an earnout. She assumed that was enough to stop working.

A buyer's price comes from a multiple of earnings. Your retirement price comes from three things only: your spending, the tax cost on the sale and on later withdrawals, and how many years the money must last.

So she decided to run the backward math before countering. That way the counteroffer has a floor under it, and she knows which number she can't go below.

If the bakery pays for your car, phone and health plan

Latoya's $150,000 a year looked fine until she pulled 12 months of bank and card statements plus the bakery's general ledger. The company paid her vehicle, phone, health premiums and a meal account. Each one lands on her personal statements the month after closing, so each gets added back to her spending.

Her daughter's college is set aside as its own lump sum before the yearly math. This example assumes it's already covered, so the $150,000 is pure living spending.

Health coverage before 65 gets one sentence here: it's a real cost and belongs on its own page.

How much must the sale leave after tax? The arithmetic, step by step

The sale must leave Latoya about $4.45 million after tax, which is roughly $5,562,500 before an illustrative 20 percent tax on the sale. Every figure below is a hypothetical round number, for illustration, and you can swap in your own with the site's calculator.

First, she wants $150,000 a year after tax. Second, she adds an illustrative $25,000 of income tax on withdrawals, which makes $175,000 a year. Third, she divides by 0.035: $175,000 ÷ 0.035 is $5 million of portfolio. Fourth, she subtracts her $550,000 solo 401(k), so the sale must leave $4.45 million after tax. Fifth, she grosses that up for the sale tax: $4.45 million ÷ 0.8 is $5,562,500 before tax.

Now a second hypothetical Latoya, identical except she sells at 56. Her solo 401(k) grows to about $700,000 (5 percent a year for illustration, no new contributions). She needs $4.3 million after tax, about $5,375,000 before tax. Five more years moved the floor only $150,000. The bakery's value has to do the rest.

Back to the first Latoya. She thought $3.2 million was enough. Less 20 percent tax, it's $2.56 million. Add $550,000 and she holds $3.11 million, which supports about $108,850 a year before tax at 3.5 percent. That's roughly $84,000 after tax if tax stays near $25,000, and that's even if the whole earnout is paid.

Withdrawal rates are rules of thumb, not promises, and a portfolio built from sale proceeds can lose value in a bad stretch of markets.

The five steps

Same owner, five years later

Which income counts in the sale year, and which limits does it cross?

The sale year carries the gain plus any ordinary-income pieces, such as depreciation recapture on ovens, mixers and delivery trucks in an asset sale. How the deal is structured belongs on its own page; here it gets one sentence.

The solo 401(k) is locked until 59½. Withdrawals before then generally carry a 10 percent additional tax, so Latoya's first eight and a half years, about $1,487,500 at $175,000 a year (8.5 × $175,000), must come from taxable sale proceeds.

Sale-year income far above $168,000 blocks a direct Roth IRA contribution that year (the IRS 2026 single phase-out runs $153,000 to $168,000). The low-income years after the sale are the opening. With the 2026 standard deduction of $16,100 single, or $24,150 as head of household while her daughter qualifies, Roth conversions from the solo 401(k) can fill low brackets. Before 59½, every converted amount starts a separate five-year count before it can be withdrawn without the 10 percent additional tax.

Low-bracket conversions save tax. Deferring the 401(k) until later only shifts it.

Selling in your early 50s means a 40-year withdrawal plan

A 51-year-old plans for 40 years or more, which is why this page uses 3.5 percent. At 4 percent, Latoya's need falls to $4,375,000 ($175,000 ÷ 0.04), about $625,000 less. We'd lean toward 3.5 percent for anyone stopping before 55, because a bad first decade is what really hurts.

Social Security is left out on purpose. Full retirement age is 67 for anyone born in 1960 or later, per the SSA, and once benefits start the yearly draw on the portfolio falls. Leaving it out keeps the floor conservative.

How long before signing should the number be tested?

Test the number before you counter, and certainly before the letter of intent is signed. Once exclusivity starts, the price is anchored and you can no longer shop the bakery to another buyer.

Testing too early has its own cost. Spending figures from before the daughter's college years, or before the bakery's perks were counted, give a floor that's too low.

Order matters too. The FAFSA uses tax information from two years before the award year, so a sale in the calendar year running from the spring of the daughter's sophomore year of high school through the fall of her junior year shows up on her freshman-year aid form.

Spending from the solo 401(k) before 59½ is the other wrong order, and it gets discovered in January. A Form 1099-R arrives with distribution code 1. The CPA explains that the $60,000 Latoya took at 52 owes a $6,000 additional tax on top of income tax. Her plan had counted the 401(k) as spendable from the day of the sale. It only becomes spendable without the penalty at 59½.

Your first moves once a number is in your head

First, total 12 months of real spending with the bakery's perks added back. Then list what each outside account would be worth once tax is paid on it. Next, run the five-step backward math at 3.5 percent. Last, hold the floor up against the cash at closing in the letter, not the headline price.

Latoya's letter said $3.2 million, but 30 percent was an earnout, so the cash at closing was $2.24 million. That's the number she measured against her floor.

A checklist to hold against your own accounts

This checklist is for you if you have an offer or a number in mind and under 20 percent of your net worth sits outside the company. Check each item against the document named.

Run it before you counter. Two hours with your statements is cheaper than a wrong floor.

• Yearly spending including company-paid perks (bank and card statements, general ledger)
• Outside savings by account type and the age each becomes usable (year-end statement for the solo 401(k))
• Illustrative tax on withdrawals (last two tax returns for income)
• Withdrawal rate for your age: 3.5 percent before 55, 4 percent in your mid-60s
• Tax cost on the sale from your CPA
• College or other lump sums set aside
• Cash at closing, not the headline price (letter of intent)

What you can work out alone and where Apollon Wealth Management comes in

You can run the five-step backward math and the checklist yourself with a calculator and your statements. Apollon Wealth Management is worth a conversation for the tax pieces: estimating the tax cost on the sale with your CPA, mapping which accounts pay for which years before 59½, and planning low-income-year Roth conversions. Each is brought to a progress meeting with the numbers in front of you.

The 3.5 and 4 percent rates, the $25,000 tax estimate and the 20 percent sale tax are illustrative, not forecasts. Social Security, pre-65 health coverage and deal structure can each move the floor, and an owner more than five years from a sale should treat the result as a starting estimate.
