How Much Is My Business Worth? The Complete NZ Seller's Valuation Guide (2026)

# How Much Is My Business Worth? The Complete NZ Seller's Valuation Guide

Every business owner, at some point, asks the same question: "How much is my business actually worth?"

Whether you're planning to sell next month, next year, or just want to know where you stand — understanding your business's value is one of the most important financial decisions you'll make.

In this guide, we break down exactly how businesses are valued in New Zealand, the key factors that drive (or destroy) your price, and the most common mistakes sellers make.

Why Accurate Valuation Matters

Getting the price wrong — in either direction — can cost you dearly:

A proper valuation gives you negotiating power, a realistic timeline, and the confidence to walk away from bad offers.

The #1 Metric: Seller's Discretionary Earnings (SDE)

In New Zealand's small-to-medium business market, the most widely used valuation method is the SDE Multiple Method.

What is SDE?

SDE (Seller's Discretionary Earnings) represents the total financial benefit a single owner-operator takes from the business each year. It's calculated as:

SDE = Net Profit + Owner's Salary + Personal Expenses + Depreciation + Interest + One-off Costs

Think of SDE as the answer to: *"If I bought this business and ran it myself, how much money would I take home?"*

Why SDE, Not Net Profit?

Net profit on your tax return is often artificially low. Many NZ business owners:

SDE "adds back" these items to reveal the true economic benefit of the business.

The SDE Multiple

Once you have your SDE, the formula is simple:

Business Value = SDE × Industry Multiple

In New Zealand (2026), typical multiples range from:

These multiples vary based on dozens of factors — which is where the nuance comes in.

10 Factors That Move Your Multiple Up or Down

Your multiple isn't fixed. Here's what pushes it higher or lower:

Factors That INCREASE Your Multiple (↑)

1. Long lease (5+ years remaining) — Gives buyers security. A short lease is a deal-killer.
2. Low owner involvement (< 20 hrs/week) — The less dependent the business is on you, the more it's worth. A business that runs itself is gold.
3. Consistent growth trend — Three years of rising revenue signals a healthy business.
4. Diversified customer base — No single client accounting for more than 10–15% of revenue.
5. Trained, stable team — Staff who stay reduce transition risk for the buyer.

Factors That DECREASE Your Multiple (↓)

1. Short or expiring lease (< 2 years) — Buyers fear losing the location. This can knock 30–50% off your price.
2. Owner works 60+ hours/week — The buyer is essentially buying a full-time job, not a business.
3. Revenue declining — Even a 5–10% annual decline dramatically lowers buyer confidence.
4. High customer concentration — If 50% of revenue comes from one client, the risk is extreme.
5. Aging equipment — Buyers will factor in replacement costs, effectively lowering your price.

Beyond SDE: Other Valuation Methods

While SDE multiples dominate the NZ small business market, you should be aware of these alternatives:

Asset-Based Valuation

Business Value = Total Assets – Total Liabilities

Best for: asset-heavy businesses (manufacturing, transport) or businesses being sold for their equipment/inventory rather than earnings.

In NZ, it's common to see listings priced as "Price + SAV" (Stock at Valuation). This means the business price is for goodwill and assets, and the stock value is calculated separately at settlement.

Revenue Multiple

Business Value = Annual Revenue × Revenue Multiple

Typically used for high-growth businesses or SaaS companies where profits haven't yet materialised but revenue trajectory is strong. Less common in traditional NZ small business sales.

Comparable Sales

What have similar businesses sold for recently? This is harder in NZ due to limited public data on business sales, but a good broker will have access to comparable transaction data.

The Hidden Value Killers

These are the things sellers often overlook that silently erode their business value:

1. Messy Books If your financials can't clearly show three years of clean P&L statements, buyers get nervous. Invest in a good accountant to prepare your books before going to market.

2. Key-Person Dependency If the business can't function without you — if customers come because of your personal relationships — the buyer is taking a massive risk.

Fix: Start delegating 6–12 months before selling. Document your processes. Introduce customers to your team.

3. Deferred Maintenance That equipment you've been nursing along? That roof that leaks? Buyers will notice, and they'll deduct the repair cost — plus a risk premium — from their offer.

4. Informal Agreements Verbal agreements with landlords, suppliers, or staff are worthless in a sale. Formalise everything in writing.

5. Unreported Revenue Some sellers proudly say "the real turnover is much higher — I just don't put it all through the books." This doesn't help you. If it's not in the books, it doesn't count. Buyers can only pay for what they can verify.

How to Increase Your Business Value Before Selling

Smart sellers start preparing 12–24 months before going to market. Here's your checklist:

Financial Optimisation - Clean up your books — three years of clear, consistent financials - Reduce unnecessary expenses (but don't cut into revenue-generating activities) - Formalise all revenue — stop any cash-in-hand practices - Separate personal expenses from business expenses

Operational Improvements - Document all processes in an operations manual - Cross-train staff so no single person is a bottleneck - Renegotiate your lease — aim for 5+ years remaining at sale time - Update aged equipment if the ROI makes sense

Growth Signals - Focus on growing revenue, even modestly — an upward trend matters more than the absolute number - Diversify your customer base - Lock in recurring revenue contracts where possible - Build a pipeline of opportunities the new owner can capitalise on

Getting Your Valuation: Your Options

1. Professional Valuer ($3,000 – $10,000+) A Chartered Accountant or accredited business valuer provides a formal, defensible valuation. Essential for businesses above $500k, legal disputes, or partnership buyouts.

2. Business Broker (Free with listing) Most brokers offer a free appraisal as part of their listing service. Be aware that some may inflate the number to win your listing. Get multiple opinions.

3. AI-Powered Valuation (Free / Instant) Modern AI valuation tools can analyse your financials against market data and industry benchmarks in minutes. These won't replace a formal valuation for legal purposes, but they're excellent for: - Getting an instant reality check before approaching a broker - Understanding which factors are driving your price up or down - Testing "what if" scenarios (e.g., "What if I extend my lease?") - Having data-backed negotiating points

Common Pricing Mistakes NZ Sellers Make

1. "I spent $500k building this business, so it's worth $500k" Your investment cost is irrelevant. The market only cares about future earnings potential.

2. "My competitor sold for $X, so mine is worth the same" No two businesses are identical. Location, lease, staff, financials — everything matters.

3. "I'll price high and negotiate down" Overpricing by more than 10–15% from market value causes buyers to skip your listing entirely. You don't get lowball offers — you get no offers.

4. "The business will be worth more next year" Maybe. But factor in the cost of your time, the risk of market changes, and the reality that a business dependent on a burnt-out owner deteriorates quickly.

When Is the Right Time to Sell?

The worst time? When you're burnt out, the lease is expiring, revenue is falling, and you *need* to sell. Desperation shows, and buyers know it.
