Partnership Valuation Calculator
Valuing a partnership is two jobs in one. First, figure out what the whole business is worth. Second, divide that value fairly among the partners, debts included. This calculator does both: a Gordon growth model valuation with every step shown, and a partner-split tab that deducts debts before dividing the equity among up to four partners.
Estimated partnership value

Net value to split

Quick Answer
A business generating $100,000 of sustainable annual cash flow, valued at a 10% required return with 3% long-term growth, is worth $1,428,571.43 under the Gordon growth model (100,000 ÷ 0.07). Split that business at a $800,000 value among four partners holding 40/30/20/10, and the shares are $320,000, $240,000, $160,000 and $80,000. The calculator above is pre-filled with both runs, so press Calculate on each tab to reproduce them.
Key takeaways
- Partnership value = annual cash flow ÷ (required rate − growth rate). The required rate must exceed the growth rate, or the model has no meaningful answer.
- Debt comes out before the split: each partner's share = (business value − debts) × ownership %. A $50,000 debt on an $800,000 business leaves $750,000 to divide.
- Small changes in the rate spread move the value a lot: at a 7% net rate the $100,000 cash flow is worth $1,428,571; at 10% it is worth $1,000,000.
- This is a pro-rata starting estimate. Minority stakes usually trade at a discount to it, and the operating agreement may prescribe its own formula.
How to use the partnership valuation calculator
Two tabs, two jobs. Start on Business valuation to price the whole business, then move to Partner split to divide it. Nothing computes until you click Calculate.
- Business valuation tab: enter the expected annual cash flow (normalized profit plus add-backs), the required rate of return an investor would demand, and the long-term growth rate. Click Calculate for the Gordon-model value with the full arithmetic shown.
- Carry the value: the "Use this value in Partner split" button moves the computed value into the second tab automatically. You can also type any value you already have.
- Partner split tab: enter business debts (optional), then each partner's ownership percentage. Click Calculate to see the net value and every partner's dollar share.
- Copy or share: both tabs have Copy my results and Share results buttons that package the outcome as text.
If the partnership is dissolving because a single owner is buying the others out, the equity buyout calculator isolates that one-owner scenario, and the company valuation calculator compares fuller valuation methods when a single Gordon estimate is not enough.
The formula: the Gordon growth model
The Gordon growth model values a perpetual stream of growing cash flow. It is the simplest member of the dividend discount model family: the present value of cash flows growing at a constant rate, forever, discounted at the required return.
Net capitalization rate = Required rate − Growth rate
Partner's share = (Business value − Debts) × (Ownership % ÷ 100)
Two honest details about how this tool behaves. First, the model blows up as the growth rate approaches the required rate: with $100,000 of cash flow, a 5% net rate gives $2,000,000 while a 10% net rate gives $1,000,000, so the growth assumption deserves the most scrutiny. Second, the tool refuses to compute when the required rate is at or below the growth rate, because the math is economically meaningless there. The constant-growth dividend discount model, its assumptions and limits are laid out in the OpenStax Principles of Finance chapter on dividend discount models, which notes the same r > g constraint.
Worked examples, verified against the tool
The calculator is pre-filled with these exact runs. Press Calculate on each tab to reproduce them.
Valuation: $100,000 of annual cash flow, a 10% required return and 3% growth. Net rate = 10% − 3% = 7%. Value = 100,000 ÷ 0.07 = $1,428,571.43.
| Net capitalization rate | Value of $100,000 cash flow |
|---|---|
| 5% | $2,000,000.00 |
| 6% | $1,666,666.67 |
| 7% (worked example) | $1,428,571.43 |
| 8% | $1,250,000.00 |
| 9% | $1,111,111.11 |
| 10% | $1,000,000.00 |
Partner split: $800,000 business value, no debts, partners at 40/30/20/10. Net value = $800,000. Shares = $320,000.00, $240,000.00, $160,000.00 and $80,000.00, which sum exactly to the total. With a $50,000 debt and only two partners at 40/30, the net is $750,000 and the shares are $300,000.00 and $225,000.00, with the tool noting that 30.00% of ownership is unassigned.
What competing calculators miss
Most pages ranking for this keyword solve only half the problem, and the ones that touch valuation hide their math:
- Brave Calculator's partnership tool: handles one partner at a time with total value × ownership %. Clean for a single buyout, but it assumes you already know the business value and gives you no way to compute it, no debt deduction, and no multi-partner view.
- Ultimate Finance Calculator's profit distribution tool: divides a total profit among up to four partners with a breakdown bar. Good for splitting this year's earnings, but profit is not value, and it never touches valuation.
- ConvertersZone's partnership split calculator: a weighted-points system (capital, work hours, IP, network) that recommends an equity split for forming a business. It answers "what should the percentages be" rather than "what is each share worth," and its weights are subjective inputs.
- cal67's partnership percentage calculator: derives ownership percentages from capital contributions. Useful at formation, but silent on what the business or any stake is worth today.
- Alumni Founders' equity calculator: startup-specific, with Carta exit data and vesting mechanics. A founder tool, not a partnership buyout tool.
- The gap this page fills: one workflow from valuation to division. A Gordon growth valuation with the arithmetic exposed, a carry button into the split, debts deducted before dividing, up to four partners shown as rows, and an honest flag when the percentages do not sum to 100%. If you are forming the split rather than valuing it, the dynamic equity split calculator is the better starting point.
Frequently asked questions
Use normalized cash flow: start from profit, then add back one-off expenses, above-market owner compensation and non-recurring items. Buyers pay for sustainable earnings, not last year's anomalies, so a single unusually good or bad year should be adjusted out.
It reflects risk. Established small businesses commonly use 10 to 15%, higher for riskier or earlier-stage ones. It must exceed the long-term growth rate and your cost of capital, and small moves in it swing the valuation sharply, so it deserves the most scrutiny of the three inputs.
When the growth rate equals or exceeds the required rate of return, the Gordon model produces a negative or infinite result, which is economically meaningless. The tool blocks that case and asks for a required rate above the growth rate.
Yes. Enter business debts and they are deducted from the total before splitting, so each partner's share reflects equity value rather than enterprise value. Debts cannot equal or exceed the business value.
A minority stake is usually worth less per percent than a controlling one. Restricted-stock studies underpinning marketability discounts span roughly 11% to 45% across studies, and lack-of-control discounts layer on top. This tool gives the pro-rata value; apply any discounts separately with professional advice.
Yes. The math works for partnerships, LLCs and LLPs, any entity where ownership is split by percentage. Check the operating agreement first, since buy-sell clauses often prescribe their own valuation formula, and that contractual formula governs over any estimate.
No. It is a transparent starting estimate both sides can inspect. For disputes, divorces or tax filings, engage a qualified business valuator: the AICPA's Statement on Standards for Valuation Services governs how CPAs develop formal conclusions of value.
A valuation cap belongs to startup convertible notes and SAFEs: it sets the maximum valuation at which an investor's note converts to equity. This calculator values an existing partnership's cash flow for buyouts and splits, a different job entirely.
