Weight is one of the few things you buy by the pound — so cost per pound is the only honest way to compare two sets. Enter what you are looking at below and this tool works out the real price per pound of each option, including shipping, and tells you whether it is a good deal or not.
Shipping is included in the cost per pound because it is the hidden cost that decides most weight purchases. Benchmarks are typical US market ranges, not live prices — always check the current listing.
What counts as a good price per pound?
Different equipment has genuinely different economics. A bumper plate costs more per pound than cast iron because you are paying for rubber that survives being dropped, not just for mass. Here is what to expect in the current US market:
| Equipment type | What to expect | Cost per lb |
|---|---|---|
| Used cast iron plates | The cheapest weight there is. Check local marketplace listings. | $0.50 – $0.75 |
| New cast iron plates | Best value for pure loading if you do not drop the bar. | $1.00 – $1.50 |
| Bumper plates | Worth it if you deadlift or clean and need to drop weight safely. | $1.60 – $2.60 |
| Urethane / competition | Premium durability and tight weight tolerance. Rarely needed at home. | $3.00 – $5.00 |
| Fixed dumbbells | Costly per pound but no setup time between sets. | $1.40 – $3.00 |
| Adjustable dumbbells | Better value per pound and far better per square foot. | $1.20 – $3.00 |
| Kettlebells | The shape costs money; buy the few weights you will actually use. | $1.50 – $3.00 |
Shipping is the cost everyone forgets
Weights are heavy, and heavy things are expensive to move. A set that looks cheap can quietly become the priciest option once freight is added — and a “free shipping” set is often just carrying the cost inside the sticker price. That is why the calculator above has a shipping field: a $200 set of used plates with $60 of freight is $0.87/lb, not $0.67/lb, and that changes which option actually wins.
This is also why local pickup dominates on price. Used cast iron bought locally is almost always the cheapest weight you can own, because you are paying nothing to move it.
How to use cost per pound sensibly
- Compare like with like. Bumpers versus cast iron on price alone is the wrong comparison — decide first whether you need to drop the bar.
- Count the weights you will actually use. A cheap 300 lb set is poor value if 100 lb of it sits unused forever.
- Factor in space. Adjustable dumbbells cost more per pound than a fixed set but far less per square foot, which matters more in a garage or spare room.
- Buy change plates separately. Small plates (2.5s and 5s) are where sets are usually worst value — cheap cast iron covers them fine.
Frequently asked questions
What is a good price per pound for weight plates?
For new cast iron, roughly $1.00–$1.50 per pound is normal. Bumper plates typically run $1.60–$2.60. Used cast iron bought locally can be $0.50–$0.75, which is the best value available if you do not need to drop the bar.
Are bumper plates worth the extra cost?
Only if you deadlift heavy or do Olympic lifts and need to drop the bar safely. If you squat, bench and press from a rack, cast iron does the same job for around half the price per pound.
Should I include shipping in cost per pound?
Always. Freight on a few hundred pounds of iron can add $0.20–$0.30 per pound, which is often enough to flip which option is cheapest.
