Our verdict

Ratio suits readers who want a quiet, straightforward drip or pour-over setup rather than a bean-to-cup espresso routine, and it earns that through a 5 years warranty and a spare parts shop. The trade-off is narrow machine types and a $299 starting point that sits well above the cheapest coffee makers.

Pros and cons

Pros

  • A 5 years warranty is longer cover than the routine buyer usually plans around, and it comes with a spare parts shop.
  • Reference models Ratio Four, Ratio Six, Ratio Eight Series 2 give you a named starting point instead of a bare product code.
  • Support runs on email, chat and phone, so you can reach a person on phone or chat as well as in the help centre.
  • Machine types stay focused on drip and pour over, which means the range is easy to understand rather than sprawling.

Cons

  • Machine types cover drip and pour over, so a reader who wants espresso from a bean-to-cup unit like Philips has nothing to compare here.
  • Milk handling is none, which rules out anyone making a flat white on the machine.
  • Prices start at $299 and climb to $699, well above the cheapest machines in this category.
  • The grinder built in is no, so GASTROBACK, which includes a grinder in its machine types, is the closer fit if you grind at home.

Who it suits

  • Drinkers who want drip or pour-over and would rather not manage beans and a grinder
  • Households that value a 5 years warranty and easy replacement parts over the lowest sticker price
  • Readers shopping in the US, where the range is listed as running

Who should look elsewhere

  • Anyone chasing espresso: Philips covers bean to cup and espresso, which this range does not.
  • Buyers who want a built-in grinder, since GASTROBACK lists espresso, drip and grinder.
  • Milk-drinkers, because milk handling here is none and neither Daewoo Electricals nor GASTROBACK gives a frother either, so check a frother separately.

Core features

Ratio builds a narrow kind of machine: drip and pour-over, and nothing that pretends to be an espresso machine. That focus is the first thing to weigh, because it tells you what the brand is for. The grinder built in is no. You grind outside the machine, which suits people who already own a grinder or buy pre-ground coffee, and it suits nobody who wants a single button to do everything. Capacity is 1.25 litres on the current Ratio brewer, a carafe size worth checking against how many people drink at once in your kitchen. Two things stand out on the ownership side. The warranty runs 5 years, which is longer than most people expect on a coffee maker. And there is a spare parts shop, so a worn part is a purchase rather than a reason to replace the whole machine.

Plans and prices

Pricing here is a purchase price, not a subscription. There is no introductory rate and no renewal cycle to compare, so the number you see is the number you pay. Entry pricing starts at $299, which is the cheapest machine in the range. That is the figure to check against the cheapest drip machines elsewhere, because it lands high in what coffee makers usually cost. The flagship sits at $699, and that is the top of the range rather than a bundle or a package. Keep both numbers beside the model names Ratio Four, Ratio Six, Ratio Eight Series 2. Buyers often assume the entry machine has the same features as the flagship, and here the grinder built in is no across the range, so the higher price buys a better machine rather than a different category of drink.

How it compares on our data

Read this section as a placement, not a verdict on taste. On entry pricing, the range ranks 44 among 65 brands, so it is toward the pricier end of the coffee makers we track. Buyers on a tight budget will find cheaper drip options in the same list. On flagship pricing, the rank is 38 out of 63. The position moves less than the entry figure, which reflects a range that stays in a consistent price band instead of jumping from a cheap model to a costly one.

The company behind it

Ratio is a US company, headquartered in the United States, and it has been building since 2012, so there is real trading history behind the machines rather than a new name on a new range. Support runs on email, chat and phone. Having a help centre alongside email, chat and phone means you can self-serve the easy questions and still reach a person when a part or a fault needs one, which pairs well with the spare parts shop.

Frequently asked questions

How much does a Ratio coffee machine cost?+

Machines start at $299 and the flagship costs $699. These are purchase prices on the machines listed, with no introductory rate and no renewal cycle, so the amount you see at the start is the amount you pay.

Which Ratio models should I compare?+

The named reference models are Ratio Four, Ratio Six, Ratio Eight Series 2. Start with the one that fits your budget, since entry pricing is $299 and the flagship is $699. Neither price changes what the range does, as the grinder built in is no throughout.

Does Ratio make espresso or froth milk?+

No. The machine types are drip and pour over, and milk handling is none, so this range does not pull espresso shots or steam milk. If a cappuccino at the press of a button matters to you, Philips with bean to cup and espresso is the closer fit.

How long is the warranty and can I get spare parts?+

The warranty runs 5 years, and there is a spare parts shop for replacements. Those two together mean a worn component is usually a part you order rather than a whole machine you replace, which matters most if you keep a machine for a long stretch.

Where can I buy a Ratio machine?+

The range runs in the US, which is also where the company is based in the United States. If you are shopping outside the US, check local availability first, since the range is listed for that market alone.

How do I get help if something goes wrong?+

Support runs on email, chat and phone. You can browse the help centre for quick answers, or reach the team by email, chat or phone when the question needs a person, which is the route to take for a fault or a replacement part.

Is Ratio expensive against other coffee makers?+

On entry pricing the range ranks 44 of 65 brands we track, which is toward the pricier end. The flagship rank is 38 of 63, so the whole range stays in a fairly tight band rather than jumping price tiers.

How large is the carafe?+

Capacity is 1.25 litres on the current Ratio brewer. Match that to how many cups you want ready at once, since a bigger pot means more coffee sitting on the warmer between rounds.
