How do we break down the running cost per cup for a coffee machine?

We split per-cup running costs into three parts: the electricity used to heat water and run the machine, water and wastewater charges, and consumables such as beans, pods or filters; the article shows those three make up the total figure for a single cup and explains how to calculate each component .

What are the typical per-cup cost ranges in South Africa for common brew types?

Typical South African ranges from the article are: filter drip or pour-over R0.30-R2.00 per cup, single-serve pod machines R4.00-R9.00 per cup, home espresso machines R3.50-R12.00 per cup, and stovetop moka pot or French press R0.25-R1.50 per cup .

How do we calculate the electricity cost per cup for our kitchen?

Use three numbers: the kWh used during brew and warm-up, your electricity price per kWh from your bill, and how many cups you get per brew; multiply kWh per cup by your R/kWh to get energy cost, then add water and consumable costs as shown in the worked example in the article .

Which factors change the per-cup total the most and why?

The article identifies three main levers: heating pattern (machines that stay on or use boilers raise standing energy cost), consumable choice (whole beans usually cheaper than capsules), and usage profile (single cups on an always-on machine raise per-cup energy versus batch brewing) .

Where can we look on Bash if we want machines that meet a specific running-cost target?

We recommend checking Bash’s Coffee Machines category to compare models by style and features and to match machines to a running-cost goal, as the article points readers there for model-level comparisons and our 2026 coffee machine comparison guide .

Coffee machine running costs per cup - typical R

How much does a single cup really cost?

When we talk about coffee machine running costs per cup, the total comes from three parts: energy to heat water and run the machine, water and wastewater charges, and the coffee consumables (beans, pods, filters). In South Africa today, a realistic per-cup range looks like this:

Filter drip or pour-over (household thermal-carafe): roughly R0.30-R2.00 per cup.
Single-serve pod machines (small capsules or K-cup style): roughly R4.00-R9.00 per cup.
Dedicated home espresso machine (steam boiler or heat-exchange): roughly R3.50-R12.00 per cup.
Stovetop moka pot or French press (no powered boiler): roughly R0.25-R1.50 per cup.

Those bands combine estimated energy and consumable costs. Energy is often the smallest line in the receipt for drip and manual methods, but it becomes the dominant factor for espresso where boiler warm-up matters. We explain the maths below so you can calculate a figure for your own kitchen.

Quick energy maths - how we calculate per-cup electricity

Start with three simple numbers: the kWh the machine uses while brewing and keeping warm, your local electricity price (cents or R per kWh), and how many cups you get per brew or reservoir fill. For example, a small drip brewer might use 0.10-0.20 kWh for a full carafe; a single espresso shot (pull) often uses under 0.01 kWh for the pump and an extra 0.1-0.3 kWh for boiler warm-up depending on design and whether the machine stays on.

Residential electricity prices in South Africa vary by supplier and tariff. Recent public schedules and municipal booklets show typical residential energy charges in the broad band of about R2.50-R4.50 per kWh depending on municipality and tariff class (estimates change with annual tariff decisions). Use your most recent electricity bill for the precise c/kWh to plug into calculations. For a quick local comparison, see Eskom’s tariff documentation and common municipal schedules.

Example calculation (simple):

Machine energy per cup: 0.05 kWh (a small drip or single-serve short cycle).
Electricity price: R3.00 per kWh.
Energy cost per cup = 0.05 × R3.00 = R0.15.

Add water (roughly R0.02-R0.10 per cup depending on municipal water tariffs), plus coffee grounds or a pod. A 250 g bag of beans that costs R80 and yields about 40 filter-strength cups adds ~R2.00 per cup (grind and strength dependent). Pods typically cost more per serving, hence the higher per-cup numbers above.

What changes the cost most?

From our experience, three levers move the per-cup total most:

Heating pattern: Machines that keep water hot (continuous warmers, always-on boilers) add a standing energy cost. Thermal-carafe brewers that heat once and stop keep hourly running costs near zero.
Consumable choice: Whole-bean grounds are almost always cheaper per cup than capsules; specialty single-origin shots push the consumable cost up quickly.
Usage profile: Making one cup here and there (especially on machines that stay on) raises per-cup energy; batch brewing for several cups spreads the warm-up cost over more servings.

If you want to compare machines by their real-world running cost (not just purchase price), our practical comparison work and testing approach help when choosing what to keep on your counter. See our Coffee machine comparison guide 2026 for a hands-on look across brew types and long-term running costs.

Single-serve pod machine	R0.05-R0.20	R0.02-R0.05	R3.50-R8.50	R3.57-R8.75

Practical steps to reduce your per-cup cost

We keep a short checklist for lowering costs without making coffee worse:

Turn appliances fully off after use (unless you make many cups per day).
Use a kettle to preheat water for manual brews rather than the machine’s boiler when possible.
Buy beans in sealed packs and grind to order - whole beans stay fresher longer and often cost less per cup than capsules.
Batch brew mornings when you need several cups; thermal carafes keep temperature without energy use.
Check local electricity and water tariffs so you know where savings will matter most.

Real South African scenarios

If you live in a metro with higher municipal energy rates, the energy line may push toward the upper end of ranges above. For low-consumption households (under ~200 kWh/month), fixed daily charges and minimum tariffs change how much each kWh effectively costs - that’s why we recommend using your actual bill numbers for the energy c/kWh input.

For people who value convenience and quick drinks on busy mornings - say a one-cup commuter routine - capsule machines trade a higher per-cup price for speed and less mess. If you mostly brew for two or more people at once, drip or French press spreads the energy warm-up across cups and nearly always lowers the total cost per cup.

How to run your own quick audit

We suggest this short audit you can do in a week:

Note how often you brew and whether the machine stays on between brews.
Find the kWh rate on your latest bill (R per kWh) and your water charge per litre or kL.
Weigh or estimate coffee used per cup (grams) and divide pack price by number of expected cups.
Calculate energy cost: estimated kWh per brew × R/kWh ÷ number of cups per brew.

If you’d like to compare models after you’ve run the audit, our Coffee & Tea Making category contains grinders, kettles and accessories that affect running cost and quality. Coffee & Tea Making We recommend pairing a sensible grinder and a thermal carafe or efficient kettle for the lowest ongoing cost without losing flavour.

We keep these figures practical and transparent so you can choose a coffee setup that fits both taste and household budgets. If you want help matching a model to a target per-cup cost, we can point you to specific categories and grinders on Bash to test next.
