Event Planner Markup Calculator

Professional event planners typically quote clients a total that combines pass-through vendor costs, a coordination markup on those costs, and a planning fee based on day rate times days worked. Client total = vendor costs + (vendor costs × markup %) + (planning days × day rate). Your fee income is markup plus planning fees — not the full client check, since vendor dollars flow to caterers, florists, venues, and rental companies. Cash flow and profit are different numbers.

Markup compensates for vendor sourcing, contract negotiation, payment coordination, and liability exposure when you sign vendor agreements on the client's behalf. Typical markups range 10% to 20% on vendor spend for established planners, but luxury weddings and corporate events may use flat planning fees with zero markup, or markup only on certain vendor categories like rentals and florals. Contract templates should spell out which model you use.

Day rate should reflect prep time beyond on-site event days — site visits, vendor emails, run-of-show drafting, rehearsal attendance, and weekend crisis calls. Some planners bill hourly for pre-event work and flat day rates for event week; this calculator uses one day-rate field. Inflate planning days to include heavy prep if you bundle rather than itemize hourly pre-production separately.

Vendor costs should match what appears on the client-facing budget — usually pre-tax quotes unless your contract states otherwise. Gratuity and service charges for catering staff are often separate line items; include them in vendor costs if the client pays through you. Sales tax on event services and taxable rentals varies by state and vendor type — this calculator does not compute tax.

Commission versus markup is a business model distinction planners must understand. Some planners earn undisclosed vendor commissions separately from client-visible markup. This calculator treats markup as an explicit percent on pass-through costs shown to the client. Adjust your model if you also receive backend commissions that change total compensation.

Assistant planner, design subcontractor, and software costs come out of your fee income in real life. This calculator shows gross planner fees before those expenses. Subtract assistant day rates, Aisle Planner or HoneyBook subscriptions, and liability insurance mentally — or reduce day rate to a net figure that already reflects subcontractor pay. Wedding season concentration means you may earn most annual fees in six months — cash reserves matter even when individual event quotes look strong.

Worked example with defaults: $25,000 vendor spend, 15% markup ($3,750), 3 planning days × $600/day ($1,800). Client pays $30,550 total. Your fee income ≈ $5,550 before assistant costs, software, and insurance — not $30,550. If vendor checks total $25,000 and you retain $5,550, your effective fee rate on vendor spend is about 22.2% including planning days. Re-run with your actual vendor total and day count for each proposal.

Business quoting estimate — not tax or legal advice. Sales tax on event services varies by state and vendor type. Planner income is generally taxable; vendor pass-through amounts may flow through your books depending on entity and contract structure.
