Separate jobs · one supplier rule
Mulch Batch Order Calculator
See how separate job minimums and increments change the total mulch to buy. Compare money only when you have complete quotes for the same scope and the supplier confirms one combined order.
Order comparison
Enter two or more job quantities
Blank volumes and quotes stay unknown. Enter the supplier’s minimum and increment; use 0 only when the supplier has no such rule.
Arithmetic only. This does not confirm stock, multiple stops, truck capacity, route timing, price, or supplier approval.
Worked example · no prices
Three small orders can round differently
Needs of 1.2, 1.3, and 1.4 yd³ with a 1.5-yd³ minimum and 0.5-yd³ steps round to 4.5 yd³ when bought separately. Combined need is 3.9 yd³, which rounds once to 4.0 yd³ under the same rule.
The 0.5-yd³ difference is quantity arithmetic—not a promised discount or proof the supplier will combine jobs.
How the arithmetic works
Round once per order being compared
For separate buying, each job is raised to the entered minimum, then rounded up to the next entered increment. For a combined buying option, the measured volumes are added first and that total is rounded once. The worksheet then compares the two order quantities.
Need to calculate the mulch volume for each job? Measure its beds in the main mulch calculator or organize several areas for one project in the mulch project planner. Those tools calculate beds within a project; this page compares independent work orders under a shared order rule.
Different addresses, dates, products, or supplier rules may require separate orders. Ask the supplier whether a combined quote is valid before using the optional price comparison. A lower quantity does not establish a lower bill.
Before you place an order
Multiple-job order questions
Does this calculator confirm that a supplier will combine the jobs?
No. Ask the supplier to confirm the material, quantity, addresses, delivery timing, stops, and fees. The calculator applies only the minimum and increment that you enter.
How does it compare separate orders with one batch order?
It rounds each work order to the entered minimum and increment, adds those rounded quantities, then rounds the combined required volume once under the same rule. The result is a quantity comparison, not a delivery or route plan.
When can I compare the quote totals?
Enter every separate delivered quote and the combined quote, use the same currency and tax basis, then check that the supplier-confirmed combined quote covers the same material, job scope, stops, timing, and fees. Blank prices stay unknown.
Does a lower batch volume mean guaranteed savings?
No. A smaller rounded order quantity does not prove a lower price. Compare complete current quotes and supplier terms; this worksheet does not fetch prices or predict savings.
