A proper burr grinder is the single biggest upgrade you can make to your coffee – bigger than the machine, bigger than the beans. The good news: you do not need to spend $200+ on a Baratza to get there. We tested the market under $100 and compared four burr grinders that actually deliver consistent grounds – the Capresso Infinity Plus, OXO Brew Compact, SHARDOR 2.0 and Hamilton Beach – on grind consistency, adjustment range, noise, static, cleanup and owner satisfaction across 11,000+ verified reviews.

The 4 Best Grinders Under $100
Capresso Infinity Plus (Black)
Best Overall Under $100
- Price
- $98.00
★ 4.4/5 from 1,684 verified Amazon reviews. The Capresso Infinity has been the default recommendation for budget burr grinders for over a decade, and the Infinity Plus improves it with commercial-grade steel burrs. Its 16 grind settings span espresso to French press, and its gear-reduction motor makes it noticeably quieter than other grinders in this class – a real quality-of-life win if you grind coffee before the household wakes up. Owners rate it 4.4 stars across 1,600+ reviews, praising consistent grounds and years of reliable service. It costs $98 – the top of this budget – but it is the grinder we would buy with our own money under $100.
- Pros
- Quiet gear-reduction motor
- Commercial-grade steel burrs
- 16 settings, espresso to French press
- Proven reliability over years
- Cons
- At the top of the under-$100 budget
- No timer for automatic dosing
- Hopper holds 8.8 oz, not huge
OXO Brew Compact Conical Burr
Best Compact Design
- Price
- $79.95
★ 4.3/5 from 568 verified Amazon reviews. OXO is the brand that thinks about the details other companies ignore, and the Compact Conical Burr shows it: a one-touch timer that stops automatically, an anti-static container that does not spray grounds everywhere, and a design that disassembles for cleaning without tools. It grinds consistently from fine to coarse for a 50g dose – enough for a full pot or several espresso shots. At $79.95 it undercuts the Capresso while delivering the same OXO quality guarantee. The trade-offs: a smaller 50g capacity and a younger review history (568 reviews at 4.3 stars) than the veterans on this list.
- Pros
- Thoughtful OXO design details
- Anti-static, easy-clean container
- One-touch auto stop
- $20 under the Capresso
- Cons
- 50g capacity is on the small side
- Fewer long-term reviews
- No grind-size labels on the dial
SHARDOR Electric Burr Grinder 2.0
Best Under $50
- Price
- $39.99
★ 4.1/5 from 6,795 verified Amazon reviews. The SHARDOR 2.0 is the most-bought burr grinder on Amazon under $50 – 6,700+ owners rate it 4.1 stars – and for $39.99 it is the honest answer for anyone who wants to leave blade grinders behind without spending real money. It offers 16 grind settings from fine espresso to coarse French press, an auto-off timer for consistent dosing, and conical burrs that produce noticeably more even grounds than any blade grinder. It is not as refined as the Capresso or OXO – expect more static and a louder motor – but at this price it beats every blade grinder on the shelf, full stop.
- Pros
- Best value on the list at $39.99
- 16 settings, espresso to French press
- 6,700+ reviews at 4.1 stars
- Auto-off timer
- Cons
- Louder motor
- More static than premium grinders
- Plastic body, lighter build
Hamilton Beach Electric Burr (16 oz)
Best for Big Pots of Drip
- Price
- $39.95
★ 4.0/5 from 2,158 verified Amazon reviews. If you grind for a full 12-cup pot every morning, the Hamilton Beach is the only grinder on this list with a genuinely large 16-ounce hopper. It serves up 18 grind settings, an easy slide dial and enough capacity for a whole bag of beans – no refilling mid-grind. Owners rate it 4.0 stars across 2,100+ reviews, and at $39.95 it costs less than half of the Capresso. The honest trade-offs: grind consistency is a step below the premium picks (fines at the coarse end), and the design feels utilitarian. For drip-coffee households on a budget, it is the right tool.
- Pros
- 16 oz hopper – grind a full bag
- 18 grind settings
- Cheap at $39.95
- 2,100+ reviews at 4.0 stars
- Cons
- Less consistent at coarse settings
- Utilitarian build
- No timer
Why burr beats blade – especially under $100
Blade grinders chop beans into uneven shards: fine dust over-extracts and turns bitter, while coarse chunks under-extract and taste sour. Burr grinders crush beans between two surfaces to a uniform size. Even the cheapest burr grinder on this list produces more even grounds than an expensive blade grinder. If you currently own a blade grinder, this is the upgrade that will improve your coffee more than any machine purchase.
What $40 vs $100 actually buys you
The SHARDOR and Hamilton Beach ($40) deliver real burr grinding at a blade-grinder price. The Capresso and OXO ($80–100) buy you three things: quieter motors, more consistent grind at the coarse end, and better build quality that lasts years longer. If you drink espresso, spend the extra $40–60 on the Capresso – consistency matters most for espresso. If you drink drip coffee and budget matters, the $40 grinders are genuinely fine.
What about the Baratza Encore?
The Baratza Encore is the gold standard of entry grinders – the machine every coffee forum recommends first. It now costs $149.95, which puts it 50% over this list's budget. If your budget stretches, it is still the best first grinder you can buy, mainly because Baratza sells every spare part and the grinder is built to be repaired for a decade. Under $100, the Capresso Infinity Plus is the closest in spirit.
Grind settings: you need more than you think
All four grinders here offer 16–18 settings, which is enough range for espresso through French press. What matters is not the number of clicks but whether each setting actually changes the grind size meaningfully and repeats consistently. The Capresso and OXO adjust most reliably; the budget pair is acceptable but coarser settings drift more. For espresso, buy the grinder with the steadiest adjustment – that is the Capresso.
FAQ
What is the best coffee grinder under $100?
The Capresso Infinity Plus ($98) is the best coffee grinder under $100: quiet gear-reduction motor, commercial-grade steel conical burrs, 16 settings from espresso to French press, and 1,600+ owners rating it 4.4 stars. For less money, the OXO Brew Compact ($79.95) is the best-designed option, and the SHARDOR 2.0 ($39.99) is the best value.
Is a $40 burr grinder worth it vs a blade grinder?
Yes – even a $40 burr grinder produces significantly more even grounds than any blade grinder, which directly improves the taste of your coffee. The SHARDOR 2.0 and Hamilton Beach both use conical burrs and offer 16–18 grind settings for under $40. The main sacrifices versus $100 grinders are noise, static and long-term build quality.
What is the best budget espresso grinder under $100?
For espresso, grind consistency is everything, so the Capresso Infinity Plus is the best budget espresso grinder under $100 – its steel conical burrs and reliable adjustment produce the most even fine grounds in this class. Note that true espresso grinding usually starts around $150–200 (Baratza Encore ESP, Fellow Opus); under $100 you get drinkable espresso, not dialed-in third-wave shots.
How many grind settings do I need?
16–18 settings, which all four grinders here offer, covers everything from espresso to French press. The number matters less than the consistency of each step and the reliability of the burrs. If you mostly brew drip or pour-over, any of these grinders gives you enough range; if you switch between espresso and French press daily, choose the Capresso for its steadier adjustment.
Bottom Line
Under $100, the Capresso Infinity Plus is the grinder to beat: quiet, consistent and proven, it is the closest thing to a Baratza Encore at half the price. The OXO Brew Compact is the best-designed alternative for smaller kitchens, the SHARDOR 2.0 is the best value at $39.99, and the Hamilton Beach is the pick for big drip pots. Whichever you choose, the jump from blade to burr will improve your coffee more than any other single purchase – and if your budget ever stretches to $150, the Baratza Encore remains the gold standard to grow into.
