1. Side-by-side scenario comparison

All figures below come directly from the source spreadsheet. The two columns to compare most carefully are annual profit and annual margin, because those bake in the empty / non-paying months.

Biggest single insight: the jump from 3 → 5 clients increases monthly profit from €32,720 to €85,370 — a +161% increase for only +€78k more revenue, because staffing cost barely moves (you only add 1 extra coach). Margin scales hard with group size, not with tariff.

2. Build your own scenario

Drag the sliders to test any combination. The cost model uses the same logic as the spreadsheet:

1 coach + 1 nurse (day) + 1 coach or nurse (night) = 3 people covering 24/7
Cost: 2×€23,400 (coach + nurse, 12h each) + €14,400 night + €2,600 ZAG = 63,800/month
Standby coverage (sleep-over allowance) slaapstandby vergoeding — click to expand + €0/mo

A coach with next-day duty can sleep over and claim a flat standby allowance per night. If woken to help, those active hours are paid €65/hr. This is in addition to the regular night-shift staff above. Rule: at most two coaches per night can claim the allowance — a 3rd coach sleeping over without next-day duty cannot claim. The slider below is a global count, all coaches combined.

3. How the math works

Berekeningsmodel
FormulaValue used
Monthly revenue = clients × tariffDirect from sliders
Monthly staff cost = day-shift cost + night-shift cost + €2,600 ZAG.
Day-shift: up to 2 base people × €23,400 (12h × €65 × 30) + any extras × €25,350 (13h × €65 × 30).
Night-shift: people × €14,400 (2h active + 10h sleep).
Default coverage = 1 coach + 1 nurse (day) + 1 coach or nurse (night) = 3 people, €63,800/mo. Slide day-shift 1-4 and night-shift 1-2 to scale up or down. Recommended minimum is 3 day-shift at ≥4 clients.
Monthly fixed cost (active) = sum of all active line items (rent, groceries, psychiatrist, utilities, founder, insurance, …)Default total €20,480. Each item can be edited or toggled off on the fixed-cost panel above. The spreadsheet's €23,080 line includes €2,600 of ZAG team meetings already counted in staff.
Monthly cost (empty) = €15,280 × fixed-cost adjustmentSpreadsheet "Totale kosten lege maand" — rent, utilities, founder, insurance only
Annual profit = (active months × monthly profit) − (empty months × empty cost) − €15,250 startupOne-off startup costs from "Opstartkosten"
Break-even months = startup costs ÷ monthly profitHow many active months needed to recoup the €15,250 launch spend
