What is the Right Markup for Construction in Nigeria?

Many Nigerian contractors confuse markup and profit margin — and the confusion costs serious money. Markup is the percentage you add on top of your cost to arrive at a selling price. Margin is the profit expressed as a percentage of that selling price. The relationship is: Markup = Margin ÷ (1 − Margin). A 15% target margin requires a 17.65% markup — not 15%.

Over a ₦100 million annual portfolio, pricing at 15% markup when you needed 15% margin costs you ₦1.76 million in lost profit every year. Multiply that by the number of contractors making this mistake and you begin to understand why so many construction businesses remain cash-strapped despite winning work.

Typical Nigerian contractor markups vary by project type:

Project Type	Typical Markup	Equivalent Margin
Residential new build	18–33%	15–25%
Commercial / office	14–25%	12–20%
Civil works / infrastructure	9–18%	8–15%
Renovation & fit-out	25–43%	20–30%

These ranges widen in high-inflation periods. During the 2024–2025 naira depreciation cycle, many contractors added a 5–10% escalation premium on top of their standard markup. Always price for current conditions — what worked in 2022 can result in a loss in 2026.

How to Calculate Overhead for a Construction Business

Overhead is the cost of running your business whether or not you are on site. Ignoring it is the single most common cause of contractor insolvency in Nigeria. Your overhead rate is:

Overhead Rate (%) = (Annual Overhead Costs ÷ Annual Direct Project Costs) × 100

Common overhead items to track for a Nigerian construction firm:

▸Office / yard rent — Lagos Island and Lekki offices run ₦3–8 million per year; mainland locations ₦1–3 million.
▸Administrative staff — office manager, estimator, accounts — salaries not charged directly to projects.
▸Vehicles — supervision pickups or SUVs: fuel, maintenance, insurance, and eventual replacement cost.
▸Tools & small equipment — power drills, levels, safety gear, depreciated over 3–5 years.
▸Business insurance — public liability, contractors all-risk, workmen's compensation under the Employees Compensation Act.
▸Professional memberships — COREN, NIA, NIQS, NIOB annual subscriptions and renewal fees.
▸Generator & diesel — unavoidable for Nigerian offices; budget ₦200,000–₦700,000 per year.
▸Marketing & business development — website, tender documents, site visits, client entertainment.

Small contractors (under ₦50m annual turnover) typically run overhead rates of 12–18%. Mid-size firms with permanent offices and staff see 15–22%. Track your actual overhead quarterly — if it is creeping above 20%, either cut costs or raise your overhead rate on future quotes before the gap compounds.

Understanding Nigerian VAT on Construction

Nigerian VAT is charged at 7.5% on most goods and services, including construction contracts. The VAT Act 2019 raised the rate from 5% to 7.5%. As a VAT-registered contractor, you collect VAT on your invoices and remit it to the FIRS monthly.

Registration threshold: Any business with annual taxable turnover above ₦25 million must register. Smaller contractors may register voluntarily to recover input VAT on materials — often worthwhile if you purchase significant quantities of taxable materials.

What is included: Construction services, project management fees, plant and equipment hire, and most material supplies. Basic food, medical, and educational services are exempt, but construction is not.

Invoicing requirements: Your VAT invoice must show your TIN, your FIRS VAT registration number, the net amount, the VAT amount calculated separately, and the gross total payable. Penalties and interest accrue on unpaid VAT from the statutory due date — currently the 21st of the following month.

Common Pricing Mistakes by Nigerian Contractors

These five errors account for the majority of under-profitable or loss-making contracts in the Nigerian construction market:

Forgetting overhead in cost calculations. Quoting only direct costs plus a profit margin leaves your office, staff and running costs uncovered. Every quote must include an overhead allocation — even at a minimum 10% — before you add profit.

Using markup when margin was intended. A contractor targeting 20% profit who applies a 20% markup earns only 16.7% margin. Over ₦50 million of annual work, this silent error costs ₦1.65 million in foregone profit every year.

Not pricing for rework or variations. Nigerian projects regularly deviate from scope — soil conditions change, clients add rooms, designs are revised late. A 5–7.5% risk allowance absorbs these costs without eating into your margin.

Ignoring retention impact on cash flow. A 5% retention on a ₦20m contract means ₦1 million is withheld for 6–18 months. Plan your working capital around this gap — or factor a finance cost into your price for long retention periods.

Underestimating material price escalation. Cement, reinforcement steel, and imported finishes can increase 20–40% during the lifetime of a 12-month contract. Lock in supplier prices where possible, limit quote validity to 30–60 days, and include a fluctuation clause in longer contracts.
