The moment you subcontract work — to a developer, a designer, a VA — you become an agency, and agencies live or die on one number: the charge-out rate. Charge the client exactly what the subcontractor costs you and you have bought yourself admin work for free. Charge too little above cost and one revision round wipes out the margin. This calculator builds the rate from cost up, the way agencies actually price. Enter the subcontractor cost per hour, your overhead multiplier (management, sales, tools, risk), and your target margin %. You get the charge-out rate, the gross margin per hour, the annual margin on a full-time equivalent, and a verdict on whether the deal is worth the management overhead. Pure arithmetic — no market claims. Every figure derives from your own inputs; nothing here depends on industry data, so the math is correct for any cost, any niche, any country. Methodology: loaded cost = subcontractor cost × overhead multiplier. Charge-out rate = loaded cost ÷ (1 − margin ÷ 100) — dividing (not adding) the margin guarantees the margin survives as a share of the final price. Gross margin per hour = charge-out − subcontractor cost. Annual margin per FTE = margin/hr × 1,800 billable hours. Cost multiple = charge-out ÷ cost. The calculator caps margin at 90% and flags margins under 15% as too thin for subcontracted work. Worked example — defaults: Second example — thin margin trap: the same $50/hr cost with a 1.3× overhead and 10% margin: loaded cost $65, charge-out $72.22, margin just $22.22/hr. One week of revisions you absorb for free, one late-paying client, and the quarter's profit is gone. The calculator flags this — the fix is margin first, volume second. Third example — pure pass-through risk: $40/hr cost, 1.2× overhead, 15% margin → $56.47/hr charge-out, only 1.41× cost. If the client learns the subcontractor's rate, the 41% markup looks like rent-seeking. Either add genuine value (QA, project management, guarantees) or accept this is a low-margin volume game. Fourth example — scaling: three subcontractors at the default economics: 3 × $126,000 = $378,000/yr of gross margin — before your own salary. That is the agency model: margin per head, multiplied by heads, minus your management capacity. The constraint is never demand; it is how many people you can manage well. Fifth example — margin vs markup: a 25% margin on a $120 charge-out is $30 — but a 25% markup on $90 loaded cost is only $112.50, a 20% margin. Confusing the two silently shaves 5 points off every deal. The calculator uses margin (÷ (1 − m)) deliberately: quote margin, think margin, and never let a spreadsheet do markup math on a margin promise. The hourly price you charge the client for subcontracted work. It starts from what the subcontractor costs you, adds your overhead (management, sales, tools, risk), and then adds your profit margin. It is not cost-plus-theft — it is the price of a managed outcome: the client buys reliability, QA, and a single throat to choke, not just hours. Think of it as two businesses in one: a staffing margin (the spread between cost and charge-out) and a services business (the management and QA you wrap around it). Freelancers who only see the staffing margin underprice the services half — and then wonder why subcontracting feels like more work for less money. The overhead multiplier is where the services business lives; set it honestly. Your best estimate of total cost per $1 of subcontractor cost. 1.0× would mean zero management cost (never true). 1.5× is lean (experienced subcontractor, light management). 2.0–2.5× is typical (active management, QA, sales effort, rework buffer). Track your actual management hours for a month × your rate, divide by subcontractor cost — that is your honest multiplier. Most freelancers undercount at first: they log the briefing call but not the three revision rounds, the invoice chasing, or the Sunday-night "quick check" that the subcontractor's work actually holds together. Add 20% to your first honest estimate — that missing fifth is the work you do without noticing. Recompute quarterly; as your briefs and checklists improve, the real multiplier falls and your margin rises without touching prices. 20–35% is the healthy band. Below 15–20%, one bad week (revisions, a disappearing subcontractor, a late-paying client) erases the profit. Above 35–40%, you need to be adding serious value — strategy, guarantees, deep QA — or the client will eventually route around you. The calculator flags margins under 15% as too thin. No. Quote the charge-out rate as the price of the outcome: "the project is $12,000". Cost-plus transparency invites the client to negotiate each line — your overhead, your margin, your subcontractor's rate — until nothing is left. Agencies sell managed outcomes; the internal math stays internal. Then your value-add must be obvious. A 2–3× multiple is defensible when you visibly manage, QA, guarantee, and de-risk the work. It looks like rent-seeking when you purely pass work through. The durable fix is genuine value: be the reason the work is better than hiring the subcontractor directly. Your charge-out rate moves with your costs — that is what the formula is for. Re-run the calculator with the new cost; the rate rises automatically if you hold overhead and margin constant. Tell the client at the next natural point (project renewal, annual review): "our delivery costs have moved, so the rate moves from $X to $Y." Never absorb cost increases silently — margin compression is how agencies die slowly. Estimate hours × charge-out rate, then add contingency. The charge-out rate already contains your margin; for fixed-price work add 15–25% contingency on the hours estimate because you carry the overrun risk, not the subcontractor. If the project goes sideways, your margin — not the subcontractor's pay — absorbs it. That is what the margin is for. Generally no — and it rarely helps if they do. Knowing your 2.4× multiple invites rate negotiations anchored to your margin rather than their market value. Pay subcontractors fairly by their market rate (good ones are worth keeping), keep your client pricing separate, and let each relationship be priced on its own merits. Fewer than you think — management is the bottleneck, not demand. Most solo operators manage 2–4 subcontractors well; beyond that you need process (briefs, QA checklists, async communication) or a project manager — which raises your overhead multiplier. Grow the multiplier honestly as you scale: the calculator's economics only work if the overhead input is real. You are the subcontractor in that deal — flip the calculator around. The agency applies its own overhead and margin on top of your rate. Price your white-label rate knowing they will mark it up 1.5–2.5×: charge enough that their markup still leaves you fairly paid, and expect less margin flexibility than direct-client work. Volume and zero sales effort are your compensation. Yes — always, before work starts. At minimum: scope, rate, payment terms, IP assignment to you (so you can assign it to the client), confidentiality, and non-solicitation of your clients. A handshake subcontractor who poaches your client costs infinitely more than the hour a simple agreement takes. (General information, not legal advice.) Two clauses freelancers most often regret omitting: a rework standard ("deliverables must meet the brief; revisions to meet the brief are included, new scope is billed extra") and a payment trigger ("you are paid when the work is accepted", not when the client pays you — otherwise you finance their late payment). Keep the agreement to two pages; a subcontractor who will not sign two pages is telling you something. Same math, different cost base. Cost-plus pricing builds your price from your own costs; the charge-out calculator builds it from a subcontractor's cost plus your overhead and margin. Use cost-plus for work you do yourself, charge-out for work others do under your management. Together they price the whole agency.Key takeaways
