Bagged vs Bulk Mulch, Soil and Gravel: Finding the Break-Even Point

Every landscape material comes two ways. You can buy it in bags from a garden center and carry it home, or you can have it delivered loose from a landscape supply yard and dumped on the driveway. People tend to have a fixed habit one way or the other. The cheaper choice actually depends on how much you need, and the tipping point is different for mulch, soil and stone.

Why the answer changes with quantity

A bag has packaging, shelf space and handling built into its price. Loose material has none of that, so it costs far less per cubic yard. But loose material has to get to you, and the delivery charge is the same whether the truck carries one yard or five.

So the comparison looks like this:

• Bags: the cost rises in a straight line with quantity, and it rises steeply.
• Bulk: the cost starts high, at the delivery fee, and then rises gently.

The two lines cross. Below the crossing point, bags are cheaper. Above it, bulk is.

The break-even formula

First turn the bag price into a price per cubic yard, so that you are comparing like with like.

A cubic yard is 27 cubic feet, so the number of bags in a yard is 27 divided by the bag size:

Then the break-even quantity is:

If you need more than that, order bulk. If you need less, buy bags.

Three worked examples

The prices below are examples to show the method. Yours will differ, and you should put your own local prices into the formula.

Mulch

Mulch in 2 cubic foot bags at $4.50. Bulk mulch at $38 a yard. Delivery $60.

• Bag price per yard: 4.50 × 13.5 = $60.75
• Saving per yard in bulk: 60.75 − 38 = $22.75
• Break-even: 60 ÷ 22.75 = 2.6 cubic yards

Mulch is the closest contest of the three. Bagged mulch is often sold at a low price in spring to get people into the store, which pushes the break-even up. For one or two beds, bags usually win. For a whole yard’s worth of beds, bulk does.

Topsoil

Topsoil in 0.75 cubic foot bags at $3. Bulk topsoil at $35 a yard. Delivery $75.

• Bag price per yard: 3 × 36 = $108
• Saving per yard in bulk: 108 − 35 = $73
• Break-even: 75 ÷ 73 = 1.0 cubic yard

Soil bags are small and heavy, so the price per yard is high. Anything more than about a yard is cheaper delivered, and a yard of soil is not much. It is one 4 × 8 raised bed.

Gravel

Pea gravel in 50 pound bags at $5.50. Bulk at $45 a ton, which is about $58 a yard. Delivery $75.

• Bag price per yard: 5.50 × 54 = $297
• Saving per yard in bulk: 297 − 58 = $239
• Break-even: 75 ÷ 239 = 0.3 cubic yards

A third of a yard is about 17 bags. Past that, bulk wins by a wide margin. Bagged stone is for patching a corner, not for laying a path.

What the formula leaves out

Price is only part of the decision. Each option has costs that do not appear on a receipt.

The hidden costs of bags

• Your time and your back. Forty bags of mulch means lifting each one four times: off the pallet, into the car, out of the car, and to the bed. That is 160 lifts.
• Several trips. A car holds perhaps 10 to 15 bags of mulch, and fewer bags of soil or stone because of the weight.
• Plastic. Every bag is a piece of plastic film to dispose of.
• Rounding. You buy whole bags, so you always buy a little more than you need. On a small job that surplus can be 10% or more.

The hidden costs of bulk

• The pile has to go somewhere. It usually lands on the driveway. You need a tarp underneath if you care about stains, and you need to move the whole pile by wheelbarrow, often the same day.
• Minimum orders. Many suppliers will not deliver less than one or two yards. Check before you plan around a half-yard delivery.
• Rounding up. Suppliers sell in half or whole yards. If you need 2.2 yards you are buying 2.5.
• Weather. A pile of soil in the rain becomes mud that weighs twice as much and will not spread. Mulch is more forgiving.
• Access. A dump truck needs a firm surface, room to tip, and no low wires or branches overhead.

The middle options

There are ways to get near-bulk prices without a full delivery.

Haul it yourself. Most supply yards will load a pickup or a trailer with a front loader. You pay the bulk price and no delivery. The limit is weight, not volume. A half-ton pickup can carry about a yard of mulch, but only about half a yard of soil and a third of a yard of gravel. Our guide to material weights and hauling has the figures.

Bulk bags. Some suppliers deliver in large woven sacks that hold about a cubic yard, lifted off the truck with a crane arm. They cost more than loose material and less than small bags, they keep the driveway clean, and they can be set down in places a dump truck cannot reach.

Split a load. If a neighbor is also mulching, one delivery fee across two households moves the break-even point down for both of you.

A quick way to decide

If you do not want to do the arithmetic, these rules of thumb hold up at typical prices:

And three situations where bags make sense whatever the numbers say:

1. You have nowhere to put a pile. No driveway, a shared entrance, or no way to get a wheelbarrow from the street to the bed.
2. You are working in stages. Bags stack in a garage and keep for months. A pile needs to be moved now.
3. You need a specific product. Specialty mixes, particular colors of mulch and some soil blends only come bagged.

Let the calculator do it

The mulch, topsoil and compost and gravel calculators each have optional boxes for the price per bag, the bulk price and the delivery fee. Fill them in and the result shows both totals for your exact quantity, including the rounding to whole bags and half yards, and says which is cheaper. That takes care of the arithmetic. The pile on the driveway is still up to you.
