When should I close my business for the day: A Comprehensive Guide

As a small business owner in Grand Rapids, MI, deciding whether to open your business on a particular day can significantly impact your bottom line. Factors such as marginal revenue, marginal cost, seasonal variations, and six-week averages should all be considered to make an informed decision. This blog post will guide you through these factors and provide a framework for evaluating whether staying open on specific days is beneficial for your business.

Understanding Marginal Revenue and Marginal Cost

Before diving into specific strategies, let's clarify the concepts of marginal revenue and marginal cost:

  • Marginal Revenue (MR): The additional revenue generated from selling one more unit of a product or service. In the context of deciding whether to open on a particular day, it’s the additional revenue generated by being open for that day.

  • Marginal Cost (MC): The additional cost incurred from producing one more unit of a product or service. For our purposes, it's the additional cost of operating your business for one extra day.

To make a profitable decision, your marginal revenue should exceed your marginal cost (MR > MC).

Evaluating Marginal Revenue and Marginal Cost

1. Calculate Marginal Revenue

To estimate the marginal revenue for opening on a specific day:

  • Historical Sales Data: Analyze your sales data for that particular day from previous periods. Look at daily sales figures and calculate an average.

  • Customer Trends: Consider customer behavior and trends. Are there specific days when customer footfall is higher due to local events or market conditions?

  • Promotions and Marketing: Assess if you have any ongoing promotions or marketing campaigns that could boost sales on that day.

For example, if you own a retail store, you might find that Saturdays generate higher sales compared to weekdays due to increased foot traffic.

2. Calculate Marginal Cost

To estimate the marginal cost of opening for one additional day:

  • Labor Costs: Calculate the cost of paying your employees for that day, including wages, benefits, and any overtime pay.

  • Utilities and Overheads: Consider the additional costs of utilities (electricity, water, heating) and other overheads such as rent and supplies.

  • Inventory Costs: Factor in the cost of any additional inventory needed to meet the day’s demand.

For instance, if running your café on a Sunday costs $300 in wages, $50 in utilities, and $150 in supplies, your total marginal cost is $500.

3. Compare Marginal Revenue and Marginal Cost

Once you have both figures, compare them:

  • If MR > MC: If the additional revenue from being open exceeds the additional cost, it’s generally a good idea to open your business on that day.

  • If MR < MC: If the additional cost outweighs the revenue, it might be more prudent to remain closed.

Considering Seasonal Variations

Seasonal variations can significantly impact your decision. Certain times of the year may bring higher foot traffic and sales, while others may be slower. Here’s how to factor in seasonal variations:

1. Identify Peak and Off-Peak Seasons

Determine your peak seasons when business is typically booming. This could be around holidays, local festivals, or specific times of the year relevant to your industry. Similarly, identify off-peak seasons when sales tend to dip.

For example, a toy store might see peak sales during the holiday season in December, while an ice cream shop might have higher sales in the summer months.

2. Adjust Marginal Revenue Estimates

During peak seasons, your marginal revenue estimates for specific days may be higher due to increased customer demand. Conversely, during off-peak seasons, these estimates might be lower.

3. Consider Seasonal Costs

Seasonal variations can also affect costs. For instance, heating costs may be higher in winter, or additional staff might be needed during busy holiday periods.

Using Six-Week Averages for Better Decision Making

Analyzing six-week averages can provide a more stable basis for your decision-making process. Here's how to incorporate six-week averages:

1. Collect Data

Gather sales and cost data for the last six weeks. This period is long enough to smooth out short-term fluctuations and provide a clearer picture of trends.

2. Calculate Averages

  • Average Daily Revenue: Calculate the average daily revenue over the six-week period.

  • Average Daily Cost: Calculate the average daily cost over the same period.

For instance, if your bakery has seen daily revenues of $400, $450, $500, $420, $480, and $470 over six weeks, the average daily revenue would be $453.33. Similarly, calculate the average daily costs.

3. Apply the Averages

Use these averages to make more informed decisions about whether to open on specific days. If the average marginal revenue consistently exceeds the average marginal cost, it’s a good indication that remaining open on those days is beneficial.

Practical Examples

Example 1: Retail Store

A retail store in Grand Rapids has the following data:

  • Average daily revenue on weekends: $1,200

  • Average daily revenue on weekdays: $800

  • Average daily cost: $700

During the holiday season, the weekend average revenue increases to $1,800.

Decision: The store should stay open on weekends and consider additional weekdays during the holiday season, as MR > MC.

Example 2: Café

A café analyzes six-week data:

  • Average daily revenue: $500

  • Average daily cost: $400

In the summer, average daily revenue increases to $700 due to higher foot traffic.

Decision: The café should stay open every day during the summer as MR > MC, but might consider closing on slower weekdays during the off-peak season if MR < MC.

Example 3: Service-Based Business

A service-based business (e.g., a salon) evaluates:

  • Peak season (summer) average daily revenue: $600

  • Off-peak season average daily revenue: $300

  • Average daily cost: $350

Decision: The salon should stay open during peak season as MR > MC but might reduce hours or close on certain days during the off-peak season when MR < MC.

Conclusion

Deciding whether to open your business on a particular day involves careful consideration of marginal revenue, marginal cost, seasonal variations, and six-week averages. By analyzing these factors, you can make informed decisions that maximize profitability and efficiency.
