At a minimum, three to five years before you want out. Best practice is to always work with the end in mind.
That is the answer, and you will find it repeated across this industry without much explanation attached. The number is not a marketing figure. It falls out of a simple observation: the things that actually raise what your business is worth take years to work, and the things you can do in the last six months mostly do not change the price.
This post is written for someone who believes they may never sell. However, every business owner will exit their business at some point; the question is whether or not it will be on your terms. Two of the unknowns that exit planning protects business owners against are an unsolicited offer and death or disability. Most owners reading it are not planning anything. That is fine. Everything below is worth knowing anyway, because the same work that prepares a business for sale is the work that makes it worth more to own.
What “planning your exit” actually means
It does not mean listing the business. It does not mean telling your employees, your competitors, or your banker anything. Planning your exit is part of sound strategic planning.
From an owner’s personal standpoint, it means knowing three things: what the business is worth today, what you would need it to be worth to fund the life you want afterward, and what stands between those two numbers. That is it. Everything else is execution.
On a broader scale, it is planning what will happen to your business if you are incapacitated or no longer here.
Most owners have not done this. The Exit Planning Institute’s 2025 Generational National State of Owner Readiness Report found that just 13% of owners have a formal exit plan. Among Baby Boomers, the owners closest to the door, 22% have a written business transition plan and only 5% have assembled a formal exit planning team. The gap gets wider closer to the transaction. In the IBBA and M&A Source Market Pulse survey for Q1 2025, 90% of recent sell-side clients were first-time sellers, and fewer than 5% had a written exit strategy in place when they first sat down with an advisor.
Read that last figure carefully. These are not owners three years out daydreaming. These are owners who had already decided to sell. Nineteen out of twenty of them arrived with nothing written down.
What you can change in three to five years
This is the case for the window, item by item.
Reducing your own indispensability. If you are the business, its value plummets when you are gone. Fixing that means hiring or promoting someone, then actually handing over the relationships, the pricing authority, the hiring decisions. Not the org chart version. The real version, where customers call them instead of you. That takes a couple of years to build and another year for a buyer to see evidence it holds.
Diversifying the customer base. If your largest account is 35% of revenue, getting it to 15% means growing everything else. That is a sales cycle problem, and sales cycles take as long as they take.
Building a track record of clean financials. Buyers look back three years, sometimes five. If this year is the first year your books are right, you have one clean year and two that raise questions. Starting now means that by the time anyone looks, all three years are the good ones.
Fixing the things that show up in due diligence. Missing contracts, undocumented leases, an ownership structure that was set up in 1998 and never revisited, employment agreements that were never signed. None of these are hard. All of them take months and cost you leverage if a buyer finds them first.
Growing earnings deliberately. Multiples climb with size. The Market Pulse Q4 2025 data shows average multiples rising from roughly 2.0x SDE for businesses under $500,000 up to 5.5x EBITDA in the $5 million to $50 million range. Moving up a bracket does two things to your price at once, because both the earnings and the multiple applied to them go up.
Getting your own financial house in order. The Exit Planning Institute found 65% of owners need to harvest value from the business to support their lifestyle afterward, and that the business represents roughly 80% to 90% of the typical owner’s net worth. If the number the business will produce does not cover the life you want, you need to know that with years to spare, not weeks.
What you cannot change in six months
Now the other side.
You cannot build management depth in six months. You can hire someone, but you cannot show a buyer that the hire worked.
You cannot fix customer concentration in six months. You can chase new accounts, and a buyer will read a sudden burst of new customers exactly as what it is.
You cannot clean up three years of financials in six months. You can restate them, and restated financials invite the question of what else was wrong.
You cannot make a bad year disappear. If earnings dipped, you either wait for the recovery or you sell into the dip.
And you cannot manufacture leverage. An owner with three years of runway can walk away from a bad offer. An owner who needs to be out by December cannot, and every buyer across the table knows the difference.
You cannot execute proper tax and estate planning to make your transaction as tax efficient as possible.
That asymmetry is the whole argument. The last six months are for executing a transaction. The three years before that are for determining what the transaction is worth.
The cost of the compressed timeline
None of this means a compressed sale fails. Businesses sell on short notice all the time. They sell for less, and on worse terms.
A rushed process usually costs you in three places at once. The multiple, because the risks you did not have time to fix are still there and get priced in. The structure, because more of the money moves into earnouts and seller notes when a buyer is uncertain. And the tax outcome, because the planning that reduces what you keep versus what you send to the IRS mostly has to happen before a letter of intent, not after.
Even a well-run process is not fast. Market Pulse data puts total time to close at six to twelve months depending on deal size, and that clock starts when you go to market. It does not include the preparation.
Why owners wait anyway
Knowing the window and using it are different things, and the reasons owners wait are usually good ones rather than lazy ones.
The business is busy. Planning an exit feels like admitting you are tired. Bringing in an advisor feels like starting something you are not ready to start. And there is a quiet superstition in it, the sense that thinking about the ending invites the ending.
There is also a practical objection worth taking seriously: you do not know when you want out, so how do you plan for a date you cannot name? The answer is that the date is not what you are planning for. You are planning for a condition. A business that could be sold well is a business that is ready whenever you decide, and it stays ready.
What the data shows is that the trigger, when it comes, is often not a decision at all. BizBuySell’s Q2 2026 Insight Report found 45% of owners citing retirement as their reason for selling and 21% citing burnout. Burnout does not arrive on a schedule you set. The same survey found 52% of owners reporting they had an exit plan while only 14% had obtained a professional valuation, which suggests a fair number of those plans are a general intention rather than a document with numbers in it.
There is no way to plan a real exit around a valuation you have never had. That is usually the first step, and it is a small one.
The five Ds, which do not check your calendar
Death. Disability. Divorce. Disagreement. Distress.
Those are the five ways owners exit businesses without planning to. They are not rare, and they are not hypothetical. If any one of them arrives before you have a plan, the timeline is set by the event and your family or your partners will be negotiating from the worst possible position.
This is the part of the argument that applies to owners who have no intention of selling at all. You may fully intend to run this company until you are eighty. You still have a spouse, a partner, a lender, and a key employee who all have exposure to what happens if you do not make it to eighty. A plan that sits in a drawer unused is cheap insurance. The absence of one is not.
A contingency plan is what answers those five questions before anyone has to ask them. It is not an exit plan and it is not a will. It is the short set of instructions that keeps the business running through the ninety days after something happens to you: who has signing authority, who talks to the bank, who tells the customers, how payroll gets met, what your family does with an ownership stake they did not ask for, and who they should call first.
The owners who most need one are the least likely to have one. The Exit Planning Institute found documented contingency plans in place for 74% of Millennial owners and 60% of Gen X owners, but only 30% of Baby Boomers, the group closest to an actual transition. The gap is wider on buy-sell agreements: 69% of Millennial owners had updated theirs within the past three years, against 16% of Baby Boomers. An agreement built around a valuation from 2011 and a partner who left in 2016 is not protection. It is something to be litigated.
This is also the one piece of this work that pays off the day it is signed rather than three years later. It takes a weekend, not a quarter, and it commits you to nothing.
The demographics make this less theoretical than it sounds. McKinsey’s Great Ownership Transfer report found that more than half of US small-business owners are now over 55, up from roughly 30% in 2002, and that one in four is 65 or older. In the Exit Planning Institute survey, 58% of Baby Boomer owners said they planned to exit within five years, and 75% of owners overall within ten.
Another non-planned factor is an unsolicited offer. This is not as uncommon as you would think.
But I do not want to sell
Then do not. The work still pays.
A business that runs without you is worth more and it is also a better business to own. You take vacations. You stop being the bottleneck on every decision. Your best people stay because there is somewhere for them to go.
A business with diversified customers is more resilient. That matters in any conditions, and conditions have been uneven. The Federal Reserve’s 2026 Report on Employer Firms found 77% of small employer firms reporting rising costs or tariff-related cost pressure.
A business with clean financials borrows more cheaply, survives a Q of E, gets completed more quickly, and tends to develop a level of trust with the buyer.
None of that requires you to sell anything. Exit planning should be part of your business strategy long before you decide to bring your business to market, and most of it is indistinguishable from just running the company well.
What this means for you
Three things you can do this quarter, none of which commit you to anything.
Write down the year you would like to stop working in the business. Not sell. Stop working on it. That date, minus three to five years, is when preparation should start, and it may already have passed.
Ask what the business would have to net you, after tax, to fund the life you want. Then compare that against the roughest possible valuation range. If those two numbers are far apart, that gap is the actual project, and it takes time.
Answer one question honestly: if you were out for ninety days starting tomorrow, what breaks? Write down the list. That list is your exit plan’s first draft, and you just built it for free.
How much time your business needs
Three to five years is a guideline, not a rule. Some businesses need eighteen months. Some need eight years, usually the ones most dependent on the founder. What is not variable is the direction of the tradeoff: every month of runway is a month of leverage, and leverage is what gets paid for at closing.
