Let’s dig into what really drives dairy farm profit per cow today.
What is the average dairy farm profit per cow?
Let’s start with the big question: how much money does a single dairy cow actually make? The dairy farm profit per cow varies significantly depending on location, milk prices, and farm efficiency. But industry data gives us some useful benchmarks to work with.
Industry benchmarks in 2025
In 2025, estimates suggest the net profit per cow dairy ranges from NZD $300 to $1,200 per year. In New Zealand, efficient operators are targeting above $1,000 per cow, while those facing higher input costs or weather issues might sit closer to $500.
In the US and UK, the numbers vary even more based on subsidies, land ownership, and herd size.
Regional differences in profit margins
Farmers in regions with stable pasture growth tend to achieve higher margins than those relying on imported feed. In New Zealand, the average milk yield per cow is around 4,400–4,800 litres, translating into a solid revenue base—if costs are under control.

Key factors that affect net profit per cow
Every cow has the potential to be profitable—or not. The key is understanding what drives or drains that profit. From feed quality to herd health, small changes can have a big impact on the dairy farm profit per cow.
Common profit boosters
- Efficient pasture management and grazing systems
- High milk yield per cow from optimal genetics
- Cost control on feed, labour, and animal health
- Use of accounting software like Xero for farm accounting
Common profit killers
- Over-reliance on supplements or imported feed
- Poor herd health and reproduction issues
- Lack of financial reporting and planning
- Ignoring seasonal price signals and input volatility
Smart budgeting with your accountant or advisor can help you spot inefficiencies and boost margins.
Cost of production per litre of milk explained
To get real about dairy farm profitability, you need to break it down to the litre. Understanding your cost of production per litre of milk is the most accurate way to benchmark yourself.
Feed and supplement costs
Feed is usually the biggest variable cost—making up 30–50% of total expenses. Homegrown feed can lower this dramatically, but for high-yielding herds, supplements are often necessary.
Labour and fixed expenses
Labour, electricity, maintenance, and compliance costs are major fixed costs that reduce your dairy farm profit per cow if not kept in check.
TABLE: Average cost breakdown per litre of milk in NZ
| Cost Category | Cost per Litre (NZD) |
|---|---|
| Feed & Supplements | $0.20 – $0.30 |
| Labour | $0.12 – $0.20 |
| Animal Health | $0.05 – $0.10 |
| Electricity & Water | $0.04 – $0.08 |
| R&M + Admin | $0.08 – $0.15 |
| Total | $0.49 – $0.83 |

How milk price per litre impacts profitability
Even if you’re efficient, a poor milk payout can crush your profits. In New Zealand, the milk price per litre is often expressed as dollars per kg of milk solids (kgMS). Understanding how fluctuations affect your dairy farm profit per cow is critical.
Example: Profit at $8/kgMS vs $6/kgMS
Let’s say your farm produces 400 kgMS per cow:
- At $8/kgMS, revenue per cow = $3,200
- At $6/kgMS, revenue per cow = $2,400
If your cost per cow is $2,000, you’d make a $1,200 profit at $8/kgMS, but only $400 at $6/kgMS—a 66% drop in profit. That’s why locking in contracts and staying efficient is so important.

Using a dairy farm profitability calculator
Want to run your own numbers? A dairy farm profitability calculator is a great tool for modelling different herd sizes, milk prices, and cost scenarios.
Inputs to include in your model
- Milk yield per cow (litres or kgMS)
- Average cost per litre
- Farmgate milk price
- Overhead costs (e.g. debt, equipment, tax)
This helps you understand both gross and net profit per cow dairy, whether you run a small or large-scale operation.
Example calculation: Small herd vs large herd
- 100 cows x $800 profit = $80,000
- 300 cows x $600 profit = $180,000
Bigger herds often benefit from economies of scale, but only if management keeps up.
