How many cups of coffee do you get from 1 kg of coffee beans?

Having a kilo of coffee beans at home sounds like a lot, but how long does it actually last? That mainly depends on how much coffee you use per cup and how you prefer to drink your coffee. Still, there is a simple way to make a good estimate of the number of cups you get from 1 kg of coffee beans.

By knowing how many grams of coffee you use on average per cup, you can easily calculate how many cups of coffee you get from a kilo of beans. Handy if you want to figure out how often you need new coffee beans or if you’re just curious about your coffee consumption.

The quick answer in short

From 1 kg of coffee beans you get on average between 100 and 140 cups of coffee. The exact number mainly depends on how many grams of coffee you use per cup. Use less coffee per cup, and you get more cups from the same kilo.

Since most people use somewhere between 7 and 10 grams of coffee per cup, the number of cups usually falls within this range. It’s not a fixed number, but a practical guideline you can easily adjust to your coffee routine.

How many grams of coffee do you use per cup?

The amount of coffee you use per cup is usually between 7 and 10 grams. That difference seems small but has a big impact on how many cups of coffee you ultimately get from 1 kg of coffee beans.

If you use around 7 grams per cup, your beans will last longer and the coffee will be a bit milder. If you go towards 9 or 10 grams, the flavour becomes fuller and stronger, but the number of cups per kilo naturally decreases. What works best for you mainly depends on your personal taste and how strong you like your coffee.

How to calculate how many cups you get from 1 kilo

One kilo of coffee beans equals 1000 grams. You divide that by the number of grams of coffee you use per cup.

For example, if you use 8 grams of coffee per cup, you divide 1000 by 8. You then get about 125 cups of coffee. Use a bit more coffee per cup, and that number decreases. Use your beans a bit more sparingly, and you get more cups from the same kilo.

With this simple calculation, you can easily adjust to your own taste and coffee routine.

Examples: how many cups with different amounts?

The number of cups you get from 1 kg of coffee beans directly depends on how much coffee you use per cup. Below you see some common examples.

  • 7 grams of coffee per cup
    You get about 140 cups from 1 kilo of coffee beans.
  • 8 grams of coffee per cup
    You get around 125 cups per kilo.
  • 9 grams of coffee per cup
    This yields about 110 cups of coffee.
  • 10 grams of coffee per cup
    Then you get around 100 cups from 1 kg of beans.

These examples show that a small difference per cup over a whole kilo quickly makes a difference of dozens of cups.

Why the number of cups per kilo can vary

The number of cups of coffee you get from 1 kg of coffee beans is not a fixed figure. That’s because several factors influence how much coffee is used per cup and how efficiently that coffee is used.

For example, the setting of your coffee machine plays a big role. Some machines dose a bit more coffee per cup by default. Also, the grind size matters: finer ground coffee releases flavour faster, so sometimes you can get away with slightly fewer grams. Additionally, your personal taste counts. If you like your coffee stronger, you automatically use more coffee per cup and get fewer cups from the same kilo.

How long does 1 kg of coffee beans last?

How long 1 kg of coffee beans lasts depends on how many cups of coffee you drink per day. Assuming an average of 8 grams of coffee per cup, you get about 125 cups per kilo.

In practice, that means:

  • 1 cup per day → about 4 months
  • 2 cups per day → about 2 months
  • 3 cups per day → about 6 weeks

This way you can see at a glance how quickly you go through a kilo of coffee beans and when it’s handy to order new beans.

Tips to use your coffee beans wisely

With a few simple adjustments, you can get more out of your coffee beans without compromising on flavour.

  • Weigh your coffee instead of dosing by feel. A few grams difference per cup adds up significantly over a whole kilo.
  • Store your coffee beans airtight, in a cool and dry place. This keeps them fresher and full of flavour for longer.
  • Grind your beans fresh, right before brewing. Fresh grinding gives more flavour, so sometimes you can use a bit less coffee.
  • Check your coffee machine’s settings. If it’s set to a strong default, you can test whether using a bit less coffee still tastes good.

By being mindful of these, you get the most out of every kilo of coffee beans.

Frequently asked questions about coffee beans and consumption
Are you losing coffee when grinding beans?
When grinding, a small amount of coffee always remains in the grinder. This loss is usually minimal, but adds up with frequent use.
Does the size of the cup affect consumption?
Larger cups often encourage a higher dose. As a result, you end up using more coffee per brew more quickly.
Does the roast affect how much coffee you use?
Dark-roasted coffee often tastes more intense, which means some people use slightly less coffee per cup. Lighter roasts, on the other hand, may call for a higher dose.
Is it cheaper to buy coffee beans per kilo?
In most cases, yes. Larger packs are often cheaper per kilo than smaller quantities.
Does your coffee consumption change due to varying settings on your machine?
Automatic programmes can use different amounts of coffee depending on the setting. You’ll notice this especially if you regularly switch between settings.
Does water quality affect how much coffee you need?
Bad water can make the flavour flat, making you inclined to use more coffee. Good water helps you get more flavour with the same amount.
Can you freeze coffee beans to make a kilo last longer?
Yes, provided you pack them airtight and freeze them in small portions. That way they stay fresh for longer without any loss of quality.
