Overview

The Variable Rate feature in One Crew provides a flexible and powerful way to manage costs that change based on quantity or usage. This allows for more precise estimating and job costing, ensuring that your pricing accurately reflects volume discounts, overtime labor rates, or other tiered pricing structures.

Purpose: To define cost rates that automatically adjust based on predefined tiers or blending rules. Scope: Applicable to both material and labor costs within your Cost Settings. These variable rates will then be automatically applied when these costs are used in estimates. Benefits:

  • Accurate Estimating: Reflect true costs by accounting for bulk discounts on materials or tiered rates for labor (e.g., overtime).

  • Increased Efficiency: Automate complex rate calculations, reducing manual effort and potential errors.

  • Improved Profitability: Ensure that your pricing strategy effectively captures cost variations, protecting your margins.

  • Transparency: Clearly see how rates are applied within estimates, aiding in review and client communication.

Use Cases

Variable Rates are ideal for situations where the unit cost of an item or labor isn't fixed. There are two primary types of variable rates, each suited for different scenarios:

  • Blended Rates:

    • When to Use: Use Blended Rates when different portions of the total quantity are charged at different rates. The final effective rate is a blend of these tiered rates.

    • Why to Use: Perfect for scenarios like:

      • Overtime Labor: The first 8 hours are at a standard rate, the next 4 hours at time-and-a-half, and anything beyond that at double-time.

      • Tiered Service Charges: A service might have a base rate for the first 'X' units, and a different rate for subsequent units.

  • Bulk Rates:

    • When to Use: Use Bulk Rates when the entire quantity purchased qualifies for a single, discounted rate once a certain threshold is met.

    • Why to Use: Commonly used for:

      • Material Volume Discounts: If you buy 0-10 tons of asphalt, it's $X/ton. If you buy 10-50 tons, all tons are $Y/ton (where Y < X).

      • Supplier Tiered Pricing: Suppliers may offer progressively lower unit prices for larger total orders.

Insight: Variable Rates bridge the gap between simple unit costing and complex, real-world pricing structures. By automating these calculations, you ensure your estimates are both accurate and efficient to produce.

Configuration

Configuring Variable Rates is done within the Cost Settings for an individual material or labor item.

  1. Navigate to Settings > Costs.

  2. Select an existing cost item or create a new one.

  3. Locate the Variable Rate section and toggle it on.

  4. Once enabled, you'll see options to define the Rate Type:

    • Blended Rate

    • Bulk Rate

Configuring Rate Tiers

Regardless of whether you choose Blended or Bulk, you'll define rate tiers. Click + New Line to add a tier. For each tier, you'll specify:

  • Minimum: The minimum quantity (e.g., units, hours) for this rate tier to apply. The first tier typically starts at 0.

  • Maximum: The maximum quantity for this rate tier. For the last tier, you can leave this as "Max" if the rate applies to all quantities above the minimum.

  • % of Base Rate: The percentage of the cost item's base Rate that should be applied for this tier. For example, 100% for standard rate, 150% for time-and-a-half, or 90% for a 10% discount.

  • Effective Rate: This field automatically calculates the actual monetary rate for this tier based on the % of Base Rate and the cost item's base Rate. You can also directly enter an Effective Rate, and the system will calculate the corresponding % of Base Rate.

Example Box: Below the rate tiers, an Example box allows you to test your configuration. Enter a quantity in the Units field, and it will show you:

  • For Bulk Rates: The single effective rate applied to all units and the total cost.

  • For Blended Rates: A breakdown of how many units fall into each tier, the rate applied to each portion, and the total blended cost.

Pro Tip: Use the Example box extensively during configuration. It provides immediate feedback on how your rate tiers will be calculated for different quantities, helping you catch any errors before saving.

Examples

Variable Rates can be applied to both material and labor costs, adapting to various pricing models.

Example 1: Bulk Rate for Materials (Asphalt)

Let's say you're configuring a cost for "Asphalt (3/4" Intermediate)" which has a base rate of $79.38 per ton. You receive volume discounts from your supplier.

Configuration (Bulk Rate):

  1. Enable Variable Rate and select Rate Type: Bulk Rate.

  2. Set up the following tiers:

    • Tier 1: Minimum 0 tn, Maximum 10 tn, % of Base Rate 100% (Effective Rate: $79.38)

    • Tier 2: Minimum 10 tn, Maximum 50 tn, % of Base Rate 90% (Effective Rate: $71.44)

    • Tier 3: Minimum 50 tn, Maximum 200 tn, % of Base Rate 80% (Effective Rate: $63.50)

    • Tier 4: Minimum 200 tn, Maximum Max, % of Base Rate 75% (Effective Rate: $59.54)

How it Works:

  • If an estimate requires 8 tons of asphalt, all 8 tons are charged at $79.38/ton.

  • If an estimate requires 30 tons, all 30 tons are charged at $71.44/ton.

  • If an estimate requires 250 tons, all 250 tons are charged at $59.54/ton.

On an estimate, if this asphalt item is used, the Rate field will be highlighted. Hovering over this rate will display a pop-up showing the bulk rate tiers and which tier is currently active based on the quantity entered in the estimate.

Example 2: Blended Rate for Labor (Driver Overtime)

Consider a "Driver" labor cost with a base rate of $50.00 per hour. Overtime rules apply.

Configuration (Blended Rate):

  1. Enable Variable Rate and select Rate Type: Blended Rate.

  2. Set up the following tiers:

    • Tier 1: Minimum 0 hrs, Maximum 8 hrs, % of Base Rate 100% (Effective Rate: $50.00)

    • Tier 2: Minimum 8 hrs, Maximum 12 hrs, % of Base Rate 150% (Effective Rate: $75.00) - Time and a half

    • Tier 3: Minimum 12 hrs, Maximum Max, % of Base Rate 200% (Effective Rate: $100.00) - Double time

How it Works:

  • If a driver works 7 hours, all 7 hours are charged at $50.00/hr.

  • If a driver works 10 hours:

    • The first 8 hours are at $50.00/hr.

    • The next 2 hours (from 8 to 10) are at $75.00/hr.

  • If a driver works 16 hours:

    • The first 8 hours are at $50.00/hr.

    • The next 4 hours (from 8 to 12) are at $75.00/hr.

    • The final 4 hours (from 12 to 16) are at $100.00/hr.

On an estimate, the driver's Rate will be a calculated blended rate. Hovering over this rate will display a pop-up detailing how the total hours are distributed across the different pay tiers.

Interacting with Variable Rates on Estimates

When a cost item with a Variable Rate is added to an estimate:

  • The Rate field will automatically populate based on the quantity and the configured variable rate rules. This field will often be highlighted (e.g., in blue) to indicate it's a calculated rate.

  • You can hover over the calculated Rate to see a breakdown of how it was derived (either the active bulk tier or the blended rate calculation).

  • If needed, you can manually override the calculated rate on the estimate.

  • To revert to the system-calculated variable rate after an override, click the three-dot menu next to the line item and select Reset Rate.

By understanding and utilizing Blended and Bulk Variable Rates, you can significantly enhance the accuracy and efficiency of your costing and estimation processes. For more information on general cost setup, please refer to [add link to relevant article on Cost Settings].
