“Move to Vietnam for cheap labour” — half true. Nominal wages in Vietnam run below China’s, but true labour cost also includes social insurance, productivity, turnover, training — and the math only works when fully loaded. This article compares Vietnam–China labour cost structures the way a CFO needs: not wage per hour, but cost per unit of output.
Comparing properly: from “cheap wages” to “unit cost”
1. Nominal wages: Vietnam lower — but the gap is narrowing
Regional minimum wages and actual industrial-park pay in Vietnam sit well below China’s coastal manufacturing provinces (Guangdong, Jiangsu, Zhejiang). But Vietnamese wages rise steadily each year while China’s hot growth phase has passed — the gap narrows over time. A 10–20 year investment decision cannot rest on this year’s wage gap.
2. Beyond wages: social insurance, union, welfare
Total labour cost = wages + social, health and unemployment insurance (employer contributions on payroll) + union fees + welfare (meals, shuttles, housing). This structure differs between Vietnam and China — both sides must be fully modelled for comparison. Classic mistake: comparing base wages, concluding “half price”, then discovering the loaded gap is a fraction of that.
3. Productivity and quality: the denominator decides
True labour cost = total cost / output. Vietnamese workers are valued as dextrous, fast learners in electronics and garments — but automated-line experience and industrial discipline in newer clusters trail China’s mature manufacturing belts. Post-Tet turnover is a major hidden cost: rehiring, retraining, Q1 production disruption. Good models use productivity at 12–24 months, not month one.
4. “Soft” costs: management, language, culture
Chinese managers in Vietnam need interpreters, cultural training, expat packages — significant in years 1–3. Meanwhile good Vietnamese managers are scarce and pricier in hot FDI zones. The full math includes management-building costs, not just direct workers.
CFO verdict: when does Vietnam win?
Vietnam wins when: (a) labour-intensive sectors (garments, electronics assembly, furniture); (b) products export to Vietnam-FTA markets (tariff synergy); (c) scale is large enough to spread management costs; (d) the horizon accepts a 1–2 year productivity ramp. China still wins when: highly automated (labour a small share), complex component supply chains absent in Vietnam, or the main market is domestic China. Don’t ask “which country is cheaper” — ask “which is cheaper for my product and my markets”.
The total-cost math — a CFO template
Spreadsheet structure (template)
Line 1 — Direct pay: base salary + allowances + bonuses (by role, by region). Line 2 — Mandatory costs: social + health + unemployment insurance (employer share) + union fees. Line 3 — Welfare: meals + shuttles + housing (if any) + health checks. Line 4 — “Hidden” costs: recruitment + training + turnover rate (rehiring cost = X months’ pay). Line 5 — Productivity: output/person/hour (at 12 months) — divide total cost by output = labour cost per unit. Two columns: Vietnam vs China — compare the bottom line, not line 1.
Common spreadsheet mistakes — three
(1) Using minimum wage: minimum wage runs 30–50% below actual pay — the sheet is wrong from line 1. (2) Forgetting turnover: omitting rehire + retrain costs — post-Tet Vietnamese turnover can hit 20–30% (enormous cost). (3) Month-one productivity: new workers run at 50–60% productivity — use steady-state (12-month) productivity, not probation output.
The 5-year scenario — never model 1 year
Vietnamese wages rise yearly — a 1-year “40% cheaper in Vietnam” sheet can become “15% cheaper” after 5 years. Method: run 3 scenarios (optimistic: slow rises; base: 5-year average; pessimistic: fast rises) — if Vietnam wins in all 3, decide confidently; if only the optimistic wins, high risk.
Beyond the spreadsheet — what numbers miss
Spreadsheets miss three things: (1) Management bandwidth: a Vietnam plant consumes headquarters attention (travel, calls, crises) — cost it as expatriate management time. (2) Quality risk: early-stage defect rates run higher — model warranty and rework costs for years 1–2. (3) Option value: a Vietnam footprint buys strategic optionality (tariff hedge, customer compliance, second source) — hard to quantify, but real; CFOs who ignore it undervalue the investment. The complete business case = spreadsheet + risks + options. Decisions on spreadsheet alone are precise but incomplete; decisions ignoring the spreadsheet are just hope.
Hidden costs in Vietnam–China comparisons — never forget
Beyond wages: (1) productivity (new Vietnamese workers reach 60–70% of skilled Chinese workers — 2–3 years to parity); (2) management (expat costs — one Chinese manager = 3–5 Vietnamese); (3) logistics (components China → Vietnam — adding freight + inventory); (4) compliance (accounting, audit, advisory — new means pricey). Model 5 years — never 1 year.
The learning-curve cost — quantifying the ramp
New factories don’t run at Chinese efficiency on day one: month 1–6 (50–60% productivity — training mode); month 7–12 (70–80% — stabilising); year 2 (85–95% — approaching parity); year 3+ (95–105% — parity or better, as Vietnamese workers master processes). Cost the ramp: lower output + higher defect rates + more supervision in years 1–2. Offset with Chinese veteran teams (seeding each line with experienced operators halves the ramp time). Investors who budget the learning curve survive it; those who don’t call it “failure” in month 8.
Vietnam–China labour cost checklist
(1) Take actual industrial-park pay (not minimum wage) in both countries for the same roles; (2) add full social/health/unemployment insurance, union, welfare — total cost per head per year; (3) estimate productivity at 12–24 months (not month one); (4) add post-Tet turnover costs (rehire, retrain); (5) add expat management costs for years 1–3; (6) divide by output → labour cost per unit; (7) layer FTA tariff effects for destination markets; (8) run a 5-year wage-growth scenario. Principle: compare cost per unit of output, not wage per hour.
