The Partnership Split: Fairness Calculator for Business Partners

Most partnerships split 50/50 because the conversation was easier on day one. This calculator does what every law firm and investment partnership has always done, for a two-person business: pays the work first (market wage, at the hours actually worked), pays the capital second (a stated return on money left in), and splits only what remains by ownership. Under that structure, 50/50 can be perfectly fair even when contributions differ wildly — because the differences are already paid for.

How it works

• Fill in The Partners tab together — hours, the market wage for each partner's actual role, capital left in, the profit pot. The tool asks the awkward questions so neither of you has to
• The three layers compute, each partner's fair total appears, and the comparison lands: the subsidy, per year, in dollars — with a plain sentence naming who is funding whom
• Works when profit can't yet cover market wages too: the layered view shows exactly who is donating what
• The Conversation tab: the opening sentence that keeps it civil, the one page to write down and sign, the annual revisit rule, and the buy-sell, deadlock and drift clauses to bring to an attorney

Built for

50/50 partners who haven't revisited the split since day one · operator-plus-investor partnerships · family businesses with a working sibling and a funding one · anyone about to form a partnership, before the handshake sets.
