Math For Delivery Gig Workers




As a DoorDash (or, any other delivery app) worker (Dasher), math is crucial for maximizing earnings, tracking expenses, and planning effectively. Here’s a breakdown of how math can help DoorDash workers in their daily operations:


1. Earnings Calculation

  • Gross Earnings Per Shift:
  • Calculate total income:
    [
    {Gross Earnings} = \sum {(Base Pay + Tips + Peak Pay)}
    ]

  • Hourly Earnings:

  • Find your average earnings per hour:
    [
    {Hourly Earnings} = \frac{{Gross Earnings}} / {{Total Hours Worked}}
    ]
    • Example: If you earn $150 in 5 hours:
      [
      {Hourly Earnings} = \frac{150}{5} = 30 \, {USD/hour}
      ]

2. Cost Management

  • Fuel Costs:
  • Calculate fuel expenses:
    [
    {Fuel Cost} = \frac{{Miles Driven}} / {{Miles Per Gallon (MPG)}} * {Fuel Price Per Gallon}
    ]

  • Maintenance Costs:

  • Estimate maintenance based on mileage:
    [
    {Maintenance Cost} = {Miles Driven} * {Maintenance Rate Per Mile}
    ]

  • Net Earnings:

  • Subtract expenses to find your profit:
    [
    {Net Earnings} = {Gross Earnings} - ({Fuel Cost} + {Maintenance Cost} + {Other Expenses})
    ]

3. Route Optimization

  • Miles Per Delivery:
  • Calculate the distance for each order:
    [
    {Miles Per Delivery} = {Delivery Miles} + {Return Miles to Starting Point}
    ]

  • Earnings Per Mile:

  • Assess if an order is worth it:
    [
    {Earnings Per Mile} = \frac{{Order Pay}} / {{Miles Driven}}
    ]

  • Time Efficiency:

  • Calculate delivery time:
    [
    {Delivery Time (min)} = {Travel Time} + {Wait Time at Restaurant}
    ]

4. Goal Tracking

  • Daily Income Goal:
  • Find how much you need to earn per hour to hit a daily target:
    [
    {Required Hourly Rate} = \frac{{Daily Goal}} / {{Hours Available}}
    ]

  • Order Acceptance Rate:

  • Monitor acceptance rate to avoid penalties:
    [
    {Acceptance Rate (\%)} = \frac{{Accepted Orders}} / {{Total Orders Offered}} * 100
    ]

5. Taxes

  • Self-Employment Tax:
  • Estimate quarterly taxes:
    [
    {Estimated Tax Payment} = {Net Earnings} * {Tax Rate (\%)}
    ]

  • Mileage Deduction:

  • Track deductible mileage for tax purposes:
    [
    {Mileage Deduction} = {Miles Driven} * {IRS Mileage Rate (e.g., $0.655/mile for 2023)}
    ]

6. Customer Metrics

  • Tip Percentage:
  • Calculate tip percentages:
    [
    {Tip Percentage (\%)} = \frac{{Tip Amount}} / {{Order Total}} * 100
    ]

  • Average Tip Per Order:

  • Monitor customer generosity:
    [
    {Average Tip} = \frac{{Total Tips}} / {{Number of Orders}}
    ]

7. Decision Making

  • Order Profitability:
  • Assess whether to accept an order:
    [
    {Profit Per Order} = {Order Pay} - ({Fuel Cost} + {Time Cost})
    ]
  • Only accept orders where the profit per order meets your desired threshold.

  • Peak Pay Analysis:

  • Evaluate shifts with bonuses:
    [
    {Shift Earnings} = ({Base Pay + Peak Pay}) * {Orders Delivered}
    ]

8. Multi-App Tracking (if applicable)

  • If you use multiple gig apps like Uber Eats or Grubhub:
  • Compare hourly rates:
    [
    {App Hourly Rate} = \frac{{Total App Earnings}} / {{Hours Worked on App}}
    ]

  • Maximize Active Time:

  • Track "active time" versus "idle time" to increase productivity.

9. Key Performance Metrics

  • Average Delivery Pay:
    [
    {Average Pay Per Delivery} = \frac{{Total Earnings}} / {{Total Deliveries}}
    ]

  • Acceptance and Completion Rates:
    [
    {Completion Rate (\%)} = \frac{{Completed Orders}} / {{Accepted Orders}} * 100
    ]


10. Long-Term Planning

  • Earnings Target for a Month:
  • Divide your target by working days:
    [
    {Daily Target} = \frac{{Monthly Target}} / {{Number of Working Days}}
    ]

  • Vehicle Replacement Savings:

  • Plan for long-term vehicle costs:
    [
    {Savings Per Month} = \frac{{Replacement Cost}} / {{Expected Lifespan in Months}}
    ]

Tools to Simplify Math:

  • Mileage Trackers: Apps like MileIQ for tracking miles.
  • Expense Apps: QuickBooks or Everlance for tracking income and expenses.
  • Earnings Calculators: Spreadsheets or apps for logging daily shifts.

By leveraging these calculations, DoorDash workers can make informed decisions, optimize earnings, and plan for sustainable growth in their gig work.?
