You open a place with someone and split the equity 50/50, because it feels fair and negotiating with a friend feels awkward. Two years later one partner has stood in the kitchen every single service and the other has checked the accounts once a month — and the equity is still 50/50.
That is not the exception, it is the norm. Research into founding teams (Wasserman, Harvard Business School) finds the same pattern over and over: teams that settle a split quickly and without much discussion almost always choose an equal one — precisely because negotiating with someone you trust feels like doubting that relationship. The problem only surfaces later, once it turns out the contributions were never equal.
Hospitality is no exception, and has its own version of it: one partner puts in the capital and signs the lease deposit, the other stands at the stove every single service for a draw that never reached market wage. Both feel underpaid for what they put in, and both are right — because nobody ever worked out what that contribution is actually worth.
That arithmetic is exactly what this article is about. Not whether 50/50 is wrong — sometimes it is precisely right — but how you check it: what capital is worth, what unpaid labour is worth, and what the risk of a personal guarantee is worth, the kind nobody sees until the business runs into trouble. At the bottom you put your own numbers into the calculator and get a recommended split, the gap against what you have now, and what that gap is worth in money.
Everything is worked out in your own browser: nothing is sent anywhere and nothing is stored. This is not legal advice — the calculator gives a starting point for the conversation, not the shareholders' agreement itself. That last part you write with a lawyer, as rule 7 below explains.
Why 'feeling fair' and 'being fair' are two different things
Psychologist J. Stacy Adams described it back in 1963: people do not judge fairness by what they receive, but by the ratio between what they put in and what they get out — compared against that same ratio for the other person. A 50/50 split feels fair to both partners on day one, when the contributions are still roughly equal. The moment one partner puts in meaningfully more hours, risk or money than the other, that ratio stops holding — even though the percentage on paper stays the same.
The sting is in what stays invisible. Capital is a number on a bank statement: everyone sees it, everyone counts it. Unpaid hours are not. A partner who works fifty-two hours a week for eighteen months on a draw below market wage has invested just as much as someone who writes a cheque — but nobody puts that on a share certificate, so it is systematically under-weighted by both partners at once.
And then there is the point at which resetting it gets expensive. Adjusting an equity split after it has been fixed is heavier legally, fiscally and emotionally than setting it correctly the first time. That is exactly why this decision carries more weight than most others you make in year one: you can revisit it later, but never without a cost that did not exist the first time round.
The 7 rules, and the arithmetic behind each one
They run in the order you actually need them: first how to compute the split itself, then how to protect it, then how to put it on paper.
1. Split on what you can count, not on the friendship
The fastest way to settle an equity split is to say 50/50 and move on — which is exactly why it is the most common split, regardless of how unequal the real contributions are. Negotiating with a friend or relative feels like distrust, so it gets skipped, and the first impression of 'fair' becomes the permanent split.
Only three things are objectively countable: the capital each partner puts in, the market value of the hours someone puts into the business, and the risk someone carries personally — a signed lease deposit or a loan taken out in their own name. Everything outside that is a feeling, and feelings change once the business has been running for two years.
The graphic below shows the same restaurant split three different ways: an equal handshake, a split on capital alone, and a split that weighs capital, unpaid hours and risk together. The three methods point at three completely different percentages — and that gap is exactly the conversation most partners skip.
Same restaurant, same two partners — the operating partner's share changes with the method.
For these two partners, the recommended share for the operating partner sits nearly twelve percentage points above an equal handshake — and nearly fifty points above a split that only looks at capital. Enter your own numbers in the calculator below for the split that fits your business.
2. Price your sweat equity, even though it never appears on paper
A partner who works fifty-two hours a week at a market wage of €27.30 an hour is delivering roughly €6,148 worth of labour a month on paper. If that partner is actually drawing only €1,890 a month, the difference — over €4,000 a month — is not a favour to the business. It is an investment, exactly like a cheque, except nothing anywhere proves it.
That arithmetic is simple enough to run today: hours per week × 4.33 × months × market rate, minus what was actually drawn. Run it over the whole period you have already been working together, not just from today — the unpaid work of the opening months counts exactly as much as this month's does.
The number that comes out is usually bigger than expected — for these two partners it reaches over €76,000 after eighteen months, more than the capital the other partner put in. That is not an argument to overhaul the business, it is an argument to put the number on the table before the equity is fixed on paper, not after.
Capital, unpaid sweat equity and the risk of a personal guarantee — added up per partner, over the time you have been working together.
The operating partner here puts in less capital, but still ends up with the larger total because of the unpaid hours. That is not a rare scenario — it is the scenario most hospitality partnerships are actually built on, and exactly why a split that only looks at the bank account so often runs off track.
3. Separate ownership from control
Who owns how many shares and who gets to make which decision are two different questions — and hospitality partnerships stall because they treat them as one. A partner with 35% of the equity can perfectly well have the final say over the menu and the staff, as long as that was agreed in advance.
Write those down separately: who decides on day-to-day spending up to a set amount, who decides on hiring, who decides on the menu, and what requires a unanimous vote — usually big investments, a second location, or selling the first. A 35% stake that carries the same vote as 65% on every decision is a different kind of partnership from a 35% stake with proportional voting rights.
Without that distinction, every disagreement collapses onto the percentage, and that percentage becomes a stand-in for a conversation that is really about trust and responsibility.
4. Use vesting — protect the business against an early departure
A stake handed over in full on day one is a stake a partner can walk away with if they leave after three months. Vesting fixes that: the stake is earned gradually over an agreed period, usually with a twelve-month cliff — nothing is earned before that date — followed by a straight-line build-up to the full stake, typically over four years.
For a hospitality business, where the opening period carries the most weight and the first twelve months decide the most, that cliff is not a formality: it protects the partner who stays against the one who concludes after two months that the trade is not for them after all, but still wants to keep half the equity.
The calculator below shows how much of the eventual stake each partner has already earned today, based on how long they have been involved — a number you never see if you only look at the percentage on paper.
5. Write the exit clause before you need it
There are only four scenarios in which a partner leaves the business: voluntarily, through disagreement, through death, or through a divorce that pulls the equity into a marital-property split. All four are predictable, and all four are cheaper to solve before they happen than after.
A buy-sell agreement fixes who may or must take over a departing partner's shares, at what valuation, and within what timeframe. Without that clause a court decides it, years later, at a cost the business could have avoided — and at a valuation nobody agreed to in advance.
Tie the valuation to a fixed method rather than an after-the-fact negotiation — HappyChef's restaurant valuation tool uses the same three methods (return, revenue, asset value) that banks and takeover specialists use, and is a neutral starting point neither partner drew up themselves.
6. Revisit the split on a fixed date, not in an argument
Today's contribution is not the contribution of three years from now. The partner who started out carrying all the hours may work fewer of them once staff have been hired; the partner who started out with all the capital may put in a second investment round for an expansion. A split that never gets revisited freezes a snapshot that stopped being accurate long ago.
So set a fixed review date into the partnership agreement — year two is common — instead of waiting until someone feels short-changed enough to open the conversation themselves. A planned review is a bookkeeping exercise; an unplanned one is a crisis.
That review date is also the moment to run the calculator below again with that year's numbers, not the opening ones. What was a fair split on day one does not have to still be fair on day seven hundred.
7. Put it on paper — with a lawyer, not a handshake
Nothing in this article replaces a shareholders' agreement drafted by a lawyer. What it does do is let you walk into that conversation with numbers instead of a gut feeling — which saves hours at an hourly rate that does not get cheaper the longer the discussion runs.
A shareholders' agreement should fix, at minimum: the split itself, the vesting, who decides what, the exit clause from rule 5, and what happens if a partner falls seriously ill for an extended period. Company law, employment law and inheritance rules differ sharply by country and legal structure — this article states none of them as a universal truth; consult a lawyer or accountant in your own country for the legal and tax structure.
The order that works: run the numbers with the tool below first, discuss the result together, and only then have a lawyer turn the conversation into legal language. Partners who arrive at the table with a number negotiate faster than partners who start from a feeling.
Put your own two partners into the calculator
Fill in what each partner puts in: capital, hours a week, the market rate for that role, how many months you have already been working together, what is currently drawn as pay, and any personal guarantee. The fields start filled in with the example above — overwrite them with your own numbers.
You get a recommended split based on capital, sweat equity and risk, the gap against what you have agreed today, and how much of the eventual stake each partner has already earned according to the vesting below.

This is not legal or tax advice. The recommended split is an arithmetic starting point for the conversation, not a shareholders' agreement — fix the final arrangement with a lawyer, as rule 7 above explains. Everything is worked out in your browser; nothing is sent anywhere or stored.
The recommended percentage and your current split are two different questions that often get tangled together. The model states what capital, hours and risk justify — not what you must do. A partner can deliberately hold a smaller stake than their contribution justifies, as long as it is a choice both of you understand and agree to.
The vesting line under the tiles is a separate number from the split itself: it does not show what each partner should eventually get, but how much of that is already earned if someone walked away today. Without vesting, every percentage is fully claimable from day one — with vesting, it only builds up over time.
What to do this week, this month and this quarter
Rewriting an equity split in one evening works for nobody — and does not need to. This order works because every step prepares the conversation for the next.
This week — run the numbers
- Fill in the calculator above with your own two partners' real numbers: capital, hours, market rate, months and pay drawn.
- Work out the sweat equity for the whole period you have already been running together, not just from today.
- Note the gap between the recommended split and what is agreed today, on paper or verbally.
- Do this apart from each other before discussing it together — that way you compare two independent estimates instead of arriving at one together.
This month — discuss it, and lock in the rest
- Discuss the gap together, with the numbers in front of you instead of a feeling.
- Set a vesting schedule, even if the business has been open for a while — a twelve-month cliff and a full build-up over four years is a common starting point.
- Explicitly separate who decides what from the equity percentage, as in rule 3 above.
- Find a lawyer who drafts partnership contracts in your own country for the shareholders' agreement.
This quarter — put it on paper and schedule the review
- Have the shareholders' agreement drafted: the split, the vesting, decision rights and the exit clause from rule 5.
- Value the business with a neutral method for the exit clause — the restaurant valuation tool is a good starting point for that conversation.
- Put a fixed review date on the calendar, year two is common, instead of waiting for a crisis.
- Run the calculator above again on every major change in the business — a second investment round, a new partner, or a partner cutting back their hours.
The equity is rarely the problem — the conversation that never happened is
Most partners who run these numbers do not conclude their split is wrong. They conclude they never checked whether it was — and that a percentage fixed on day one is still being treated as settled two years later, while the contributions have long since changed.
That is good news, because fixing it costs no money — it costs one evening of arithmetic and a conversation most partners should have had before they opened the business in the first place. Capital, sweat equity and risk are all three countable; the only thing missing was the calculator.
Run the same arithmetic next on the rest of the business. Getting the financing right decides how much capital ever comes in, and a solid business plan decides what it is for — together with this split, those are the three decisions you rarely undo without a cost.
