Model profit impact before you spend – from menu changes and labor shifts to marketing campaigns and new equipment. Turn daily sales data into clear ROI, payback, and budget guardrails.
Why it matters
Benefits
Model how menu mix, vendor price changes, and staffing levels affect food cost %, labor %, and prime cost by daypart. Set realistic weekly budgets that match forecasted covers and check averages.
Estimate incremental profit – not just incremental sales – after accounting for discount depth, third-party fees, packaging, and cannibalization of dine-in traffic.
Compare equipment (oven, fryer, refrigeration), POS upgrades, and kitchen automation using payback period, monthly cash impact, and maintenance assumptions – so you don’t tie up cash in low-return purchases.
Turn goals into numbers: covers, labor hours, prep waste, comps, and COGS. Share a single plan that connects daily actions on the floor to monthly profitability.
Use cases
Challenge
A restaurant wants to raise prices and adjust portion sizes but worries about guest pushback and whether higher prices will actually improve margin once mix shifts.
Solution
Use the calculator to model contribution margin per item, expected mix changes, and elasticity assumptions. The budget planner translates the new menu mix into weekly COGS and gross profit targets by daypart.
Challenge
Weekend service is chaotic, but adding staff could push labor % too high and erase the benefit of higher sales.
Solution
Run staffing scenarios using forecasted covers, average ticket, and labor hours by role (FOH, BOH, prep). See the break-even point where faster turns and higher throughput offset added labor cost.
Challenge
The team is spending on ads and discounts without a clear view of which campaigns drive profitable traffic versus low-margin orders.
Solution
Plan campaigns with expected CAC, redemption rate, and contribution margin by channel. The tool calculates ROI and sets spend caps so promotions stay within margin and cash flow constraints.

FAQ
A P&L is backward-looking – it tells you what happened after the month closes. An ROI calculator is forward-looking – it estimates the profit impact of a decision before you commit. For restaurants, it connects operational levers (covers, check average, menu mix, food cost %, labor hours, third-party fees, comps) to outcomes like contribution margin, prime cost, payback period, and cash flow. That makes it easier to choose between competing initiatives – for example, a new happy hour, a kitchen equipment purchase, or a delivery promo.
Start with sales by channel (dine-in, takeout, delivery), average check, covers or order count, and current food cost % and labor %. Add key assumptions like discount rate, third-party commission and delivery fees, packaging cost per order, and expected lift in traffic. For capex, include purchase price, financing terms if any, maintenance, and the operational benefit – for example, fewer labor hours, faster ticket times, reduced waste, or higher throughput.
Yes – it’s designed to separate revenue from profit by accounting for marketplace commissions, service fees, promo funding, refunds, and packaging. You can compare scenarios like increasing delivery radius, running a 20% off promo, or launching a virtual brand, and see the impact on contribution margin per order and overall weekly cash flow.
Build a weekly forecast by daypart and channel, then allocate targets for COGS, labor hours, and controllables (repairs, supplies, marketing). The planner turns those into measurable guardrails – such as max labor hours per shift, target food cost % by category, and acceptable comp limits. Managers can track performance daily and adjust scheduling, ordering, and prep before results hit the month-end P&L.
