How Many Staff Do You Need? A Simple Cafe Staffing Calculator

Picture this: It’s a Saturday morning, the line at your cafe stretches out the door, and the espresso machine is wheezing from overuse. You glance at your schedule and panic sets in. You’re short-staffed. Again. The phone is ringing off the hook with to-go orders, and your customers are getting restless. Drinks are backed up, food is late, and the stress is palpable. Sound familiar? This is the daily reality for many cafe and restaurant owners and managers. One of the biggest challenges we face is getting the staff levels right, every single shift.

The Staffing Nightmare: A Common Cafe Problem

Running a cafe is a delicate balancing act. Too few staff, and your customers suffer from slow service and a poor experience. Too many, and you’re bleeding money on unnecessary labor costs. Finding the sweet spot – the perfect number of employees – is a constant struggle, and often a guessing game. It’s a problem that impacts everything, from customer satisfaction and team morale to your bottom line.

Consider Sarah, a cafe owner in Austin. She’s been using a spreadsheet to manage her team of 15 employees. She spends hours each week figuring out who’s available, who has requested time off, and who’s needed for each shift based on her gut feeling and past data. This method is time-consuming, prone to errors, and leaves her scrambling when unexpected situations arise, like a no-show employee. She’s constantly frustrated by overstaffing during slower periods and understaffing during peak times. Managing staff with a manual system can feel like trying to nail jelly to a tree.

The Crucial Factors in Cafe Staffing

Before you can even begin to think about numbers, you need to understand the variables at play. Several key factors impact how many employees you need on any given shift:

Customer Volume

This is the big one. How many customers do you typically serve during a specific time period? Track your sales by the hour, day, and week to identify peak hours and slow periods. This data is critical for accurate cafe staff planning. Software like Shifty can help you track these metrics in real-time.

Service Style

Are you a fast-casual cafe with counter service, or a sit-down restaurant with table service? The service style significantly impacts staffing needs. Table service requires more servers and potentially bussers, while counter service typically needs more baristas and food prep staff.

Menu Complexity

A simple menu with pre-made items requires fewer staff than a complex menu with made-to-order dishes. The more complicated the menu, the more time it takes to prepare each item, and the more staff you’ll need in the kitchen and on the service line.

The Season

Seasonal changes significantly affect your business. Summer months may see a surge in customers while winter can be slower. Adjust your how you schedule part-time employees to account for these fluctuations.

Building Your Simple Staffing Calculator

Let’s move from theory to action. Here’s a simple, actionable process you can use, step-by-step to get started.

Step 1: Determine Your Peak Customer Volume

Review your sales data to identify your busiest hours of the day and days of the week. For example, if you consistently serve 100 customers between 10 AM and 11 AM on Saturdays, that’s your peak hour. Write that number down.

Step 2: Calculate Staffing Needs Per Task

Break down the tasks performed during a shift. Consider these, and assign staff needs for your busy hour:

• Barista: How many espresso machines do you have? Figure one barista per machine, or per every 25-30 orders.
• Cashier: One cashier can handle about 15-20 transactions per hour, depending on your POS system and payment methods.
• Food Prep/Line Cook: Factor in menu complexity and ticket times. Plan for one prep cook and one or two cooks on the line during rush hours.
• Service Staff (Bussers, Runners): In a table-service environment, plan for one busser or runner for every 4-5 tables, or one per 30 customers.

Step 3: Estimate Employee Numbers

Calculate total employees based on these tasks. For example, if your peak hour requires 2 baristas, 1 cashier, and 1 food prep, you need at least 4 employees. This is your BASE. Add buffer for error.

Pro Tip: Always add a buffer. Life happens. Build in an extra staff member or two to handle unexpected rushes or employee absences. This prevents customer frustration and keeps your team from feeling overwhelmed. Remember to check out our article on handling no-show employees.

Step 4: Adapt for Non-Peak Hours

Reduce staffing levels during slower periods. You might only need one barista and a cashier between 2 PM and 4 PM on weekdays. This is where Morning vs Evening Shifts and your knowledge of customer traffic come into play.

The Challenges of Manual Scheduling

Imagine doing all this manually – on a spreadsheet, on a whiteboard, or worse, in your head. It’s a recipe for headaches and errors. Manual scheduling is labor-intensive, time-consuming, and leaves you vulnerable to understaffing or overstaffing. It’s also extremely difficult to adjust and communicate changes in real-time, leaving your staff constantly in the dark.

The Power of Data-Driven Scheduling

Tracking your labor costs is essential for profitability. Without it, you are basically flying blind. Using your point-of-sale (POS) system and/or a labor cost tracking tool to capture sales, hours worked, and labor costs. Use that data to identify inefficiencies, optimize your staffing, and make informed decisions.

Here’s a simplified look at the difference:

Using technology allows you to respond quickly to changing demands and make data-driven decisions that will help you cut labor costs, improve staff morale, and increase profitability. Consider reading about how better scheduling reduces employee turnover, too.

Embrace Flexible Scheduling

Flexible scheduling is the key to managing labor costs effectively. Here are some strategies:

Split Shifts

Use split shifts during peak hours when you need full staffing levels and reduce them during slower periods. Be mindful of fairness; rotation or equal distribution of split shifts is essential.

Part-Time Staffing

Utilize part-time employees to fill in the gaps during your busiest times. This is especially helpful during lunch rushes or weekend mornings. Use our free employee availability form template to find out when your employees are available.

Shift Swapping

Implement a shift-swapping policy so employees can trade shifts when necessary. This increases flexibility and can help you avoid last-minute call-outs and shift coverage gaps. Learn more about it with our shift-swap policy template.
