How much do I need after selling my business?

Selling a business is often talked about as the finish line. It isn't, it's a new question. Before the sale, the question was "what's this worth." After the sale, it's "does what I actually walked away with cover the life I want next," and those two numbers are frequently very different from each other.

Why the sale price isn't the number

The headline figure that gets talked about, at the pub, in the press release, in your own head, is rarely the number that lands. Capital gains tax, any outstanding business debt or director's loan settled on completion, deal costs, and often a chunk of deferred consideration or an earn-out that isn't actually liquid yet, all sit between the headline price and what you can genuinely treat as spendable. Getting a clear, honest figure for net proceeds, not the number in the deal announcement, is the real starting point.

The two things that actually decide if it's enough

Once you know the real net figure, two separate questions decide whether it's actually enough:

1. Are you earning anything else, ever again? Fully stopping work and living entirely off the proceeds is a very different sum to semi-retiring, consulting, or building something new that brings in some income. The same pot can be comfortably enough for one of those and not for another.

2. How much of it is actually liquid right now? Proceeds tied up in an earn-out, deferred consideration, or loan notes aren't available to draw down today, even though they show up in the "what I sold for" figure. Your real, current number is what's liquid now, with anything deferred treated as a future top-up, not counted twice.

What people usually miss

A few things come up again and again once someone actually sits down and works through the real picture after a sale:

Treating the whole headline sum as spendable. Tax already due, or still to be paid on deferred consideration as it lands, quietly shrinks the real number well below what the deal announcement suggested.

Forgetting pensions built up during the years running the business. Old workplace or personal pensions from before the business started often sit forgotten, still doing their own thing in the background, and they're part of the real total picture even though they weren't part of the deal.

No plan for what the days actually look like. This isn't a financial number, but it drives one: people who move straight from running something demanding to nothing structured often find the biggest adjustment isn't the money, it's the shape of the week. That shift tends to affect spending decisions either way, worth naming honestly rather than assuming it'll sort itself out.

The backdrop that makes this harder right now

None of this happens in a vacuum. A few things about the current environment make getting this right more urgent, not less:

Inflation has been stickier than expected. Even at more "normal" headline rates, prices for everyday essentials have kept climbing, which quietly erodes a fixed budget faster than most people plan for. A number that works on paper today can fall short a few years in if it wasn't stress-tested against inflation.

Cash sitting in a typical current or easy-access savings account is losing real value. Sale proceeds often sit in cash for a while immediately after completion while decisions get made, which is sensible short term, but when inflation runs ahead of the interest being paid, that buffer is quietly shrinking in what it can actually buy the longer it sits idle.

Pensions are no longer the inheritance tax shelter they used to be. Legislation confirmed in 2026 means that from 6 April 2027, most unused pension funds and death benefits will be counted as part of your estate for inheritance tax, closing a gap that pensions have used for decades as a tax-efficient way to pass on wealth. That's directly relevant to how sale proceeds get allocated across pensions versus other wrappers.

The room to shelter cash from tax is also shrinking. From April 2027, the Cash ISA allowance for anyone under 65 is falling from £20,000 to £12,000, with the rest of the £20,000 total ISA allowance only usable in stocks and shares or similar wrappers. A new charge is also being introduced on cash left sitting inside a stocks and shares ISA, specifically to close that workaround. For proceeds that were sitting in cash, this changes the sums on how they're best held.

General economic uncertainty, whatever's dominating the headlines this year, is a reason to build a plan with some flexibility in it, not a reason to delay building one at all.

So what's your actual number?

Generic rules of thumb get you a ballpark, but your real number depends on things a calculator can't guess: exactly what's liquid today versus deferred, what tax is still outstanding, whether any income is planned going forward, and how existing pensions and other assets fit alongside the proceeds. That's a personal calculation, not a population average.
