Read the methodology01 The home improvement cost desk
Order the right amount of gravel.
Use this free, transparent tool to plan the material order before you buy or compare a quote.
02 Start with the scope
Know how much gravel to order.
Measure the area, choose a depth and get a cubic-yard estimate with a supplier-friendly weight check.

03 Trust the number, not the guess
Read the model card.
Every result carries the version, date and boundary of the assumptions behind it. That keeps a useful planning range from looking like a promise.
Area × depth gives cubic yards or metres; a reference density is used only as a weight check, with overage applied for settling and uneven ground.
Example: A 40 × 10 ft area at 4 in is about 4.9 yd³ before waste; with a 10% allowance, plan for about 5.4 yd³.

Why Renovation Range exists03 Read the result
Order gravel by volume
then check the weight.
Measure the area and depth first, then use the reference density to sanity-check a supplier quote in tons or tonnes.
Depth changes the order faster than length.
Multiply length × width × depth to find the base volume. Then add overage for settling, edges and uneven ground. Driveways, paths and drainage trenches often use different depths.
Rock type, moisture and compaction change the delivered weight. Use the tons or tonnes figure as a check, then ask the supplier which unit they sell.
04 Make the estimate legible
No black box.
Just better context.
A useful estimate does not pretend to be a bid. It gives you a sensible range, names the assumptions, and makes the next conversation less lopsided.
Three numbers beat one.
Low, expected, and high show uncertainty honestly — especially when labor and site conditions vary.
Show your work.
Materials, labor, gates, removal, and permits stay separate, so you can see what changed.
Local is a promise.
We only call a number local when the underlying data is local. Otherwise, we label it a baseline.
05 Before you sign anything
Turn a ballpark
into a better question.
Bring the breakdown with you. A good contractor will be able to tell you which line items are realistic for your property and why.
See the checklist01Is removal and haul-away included?+
Ask whether demolition, loading, disposal fees and final cleanup are included or priced separately. A low quote can move quickly when haul-away is missing.
02What does the labor line cover?+
Have the contractor spell out preparation, installation, equipment, cleanup and the crew’s scope. Compare the same work line by line, not just the final total.
03Are permits, gates, and site conditions scoped?+
Confirm permit responsibility, gate count and hardware, access, grading, drainage, excavation and any conditions that were not visible from the initial measurement.
04What could move this range after the site visit?+
Ask what the contractor still needs to verify: exact quantities, soil, utilities, access, material availability, taxes, disposal and code requirements. Those are the honest range movers.
07 Read the fine print
The short version.
Is this a contractor quote?
No. It is a reference estimate built from the assumptions shown on the page. A site visit and written scope are still the final word.
Why does location change the number?
Labor, material availability, permits, and site conditions vary by market. The model shows the factor and the assumptions so you can pressure-test a quote.
