JV profit split calculator
A JV profit split has two moving parts: the priority return that accrues on the partner's cash before anything is shared, and the split of what remains. Enter your scheme profit and proposed terms, and see what each party actually banks.
Priority returns, waterfalls and splits are negotiated deal by deal. Send us the scheme and your target structure and we will tell you what partners will actually agree to.
How the priority return works before any profit is split
The priority return is the term developers most often underestimate when they hear a headline split. It is a coupon on the partner's invested cash, usually 8 to 12 per cent per annum as of June 2026, and it accrues for the life of the project and is paid before the split is calculated. The calculator applies it exactly that way: on the default inputs, £600,000 of partner equity at 10 per cent per annum over 18 months accrues £90,000, which comes off the top of the £500,000 scheme profit before anything is shared. The priority return is capped at the profit available, so on a poor outcome the partner takes what profit exists and the residual to split is zero.
Notice what this does to time. The split percentages are fixed, but the priority return grows every month, so a six-month programme overrun on the default deal adds £30,000 to the partner's side before the split, all of it effectively out of your share. When you negotiate a JV, the priority return rate and how it is measured matter as much as the headline split, a point covered in depth in our guide to profit split structures.
The residual split: what each party banks
After the priority return, the residual profit is split at the agreed percentages. On the defaults, £500,000 of profit less the £90,000 priority return leaves £410,000 to split 50/50: £205,000 to you, and £295,000 in total to the partner, their priority return plus their half of the residual. The calculator shows the partner's total annualised return so you can sense-check whether proposed terms are within the market range, and frames your side in the two numbers that matter: profit in pounds, and return on any cash you put in. Where you invest nothing, the result is profit earned with none of your own cash in the deal, which is the core case for joint venture development finance in the first place.
Reading your return on equity
Return on equity (ROE) is your profit divided by your cash in. It is the number to compare structures with, because pounds of profit alone hide what your capital did. £205,000 earned with zero cash invested cannot be expressed as a percentage at all; £205,000 earned on £100,000 invested is a 205 per cent return over the term. Run the same scheme with different splits, priority returns and cash contributions and watch how the ROE moves: contributing some cash usually buys a better split, and whether that trade pays depends entirely on the numbers, not the principle. What partners expect in governance and security alongside these economics is covered on our development equity page.
One framing note: this site works for developers raising capital. The partner-side figures here exist so you can judge what you are giving up against the market, not as a description of any investment offer. Outputs are illustrative, based on a simple priority-return-then-split waterfall, and are not a quote or advice; real shareholders' agreements add capital return mechanics, hurdles and reserved matters that change the arithmetic.
Frequently asked questions
What is a priority return in a property JV?
A priority return is a coupon, typically 8 to 12 per cent per annum as of June 2026, that accrues on the funding partner's invested cash and is paid out of profit before any split is calculated. On £600,000 invested for 18 months at 10 per cent, the priority return is £90,000. Only the profit remaining after that £90,000 is split between developer and partner, which is why a 50/50 JV with a priority return pays the developer materially less than a plain 50/50.
How is profit split in a development joint venture?
The standard waterfall runs in a fixed order at completion: the senior lender is repaid, the partner's capital is returned, the partner's priority return is paid, and the residual profit is then split at the agreed percentages. A 50/50 residual split is a common starting point for an experienced developer as of June 2026; first-scheme developers more often see 35 to 45 per cent of the residual. The exact split tracks track record, who sourced the site and how much cash the developer contributes.
What happens to the priority return if the scheme makes less profit than expected?
The priority return ranks ahead of the split, so it absorbs the shortfall first from the developer's side. In this calculator the priority return is capped at the available profit: if the scheme makes £80,000 and the accrued priority return is £90,000, the partner takes the full £80,000 and the residual to split is zero. Every month of programme slippage also grows the accrued return, so delay costs the developer twice, once in extra finance costs and again in a larger priority return.
What is developer return on equity in a JV and why does it matter?
Return on equity (ROE) is your profit divided by the cash you personally put into the deal. In a full JV with no developer cash the calculator shows your profit earned with nothing invested, which is the structure's main attraction. Where you do contribute cash, ROE lets you compare the JV against simply funding a smaller scheme yourself: £150,000 of profit on £100,000 invested over 18 months is a 150 per cent return on your money, far above what the same cash earns at lower leverage.
Can the developer put no money into a JV?
Yes, and full JV structures where the partner funds the entire equity slice are common. Set the your cash in field to zero to model it. Expect the trade-off in the split: partners funding 100 per cent of the equity typically hold the developer to 35 to 50 per cent of residual profit and apply harder scrutiny to track record and the build contract, because the developer has no cash at risk alongside them.
