The answer before the details
The useful countertop dishwasher cost is the complete setup plus ongoing supplies and utilities. Use the model’s documented consumption and your own rates, then weigh the repeated dishwashing work it would take over. We do not promise a universal payback period.

Start with the chore you are buying your way out of
A countertop dishwasher is easier to justify when it can take over a recurring load of washable plates, cups and bowls. If your daily washing is mostly oversized cookware, the purchase may leave your biggest frustration untouched.
Write down what is actually in the sink after a normal day. Compare that load with the rack dimensions, not just the appliance’s capacity label. Our HAVA and Danby comparison explains the known loading limits.
Take a one-day dish inventory.
- Count plates, cups and bowls.
- Set oversized cookware aside.
- Note what must be washed by hand.
That is the load your purchase needs to help with.

Would a countertop dishwasher handle your everyday dishes?
Keep a dish diary for one to seven ordinary days. Count the items you actually wash, then separate confirmed dishwasher-safe pieces from handwash-only and unresolved items. This is a shopping checklist—not a rack-capacity or cleaning-performance test.
- Record the total number used during your observation period, including repeat uses of the same plate.
- Use separate rows for items with different care rules. Count each fork or spoon as one item; do not compare item counts with place settings.
- Note the biggest dimensions and the chores you most want to stop doing. A pan and a teaspoon each count as one item, but do not take equal space or effort.
Use the plan before spending money
Approved does not mean it fits. Compare your likely mixed load with the plate-size evidence and loading checks. Then check the counter space and installation requirements. Keep unknown items out of the machine until their care is confirmed.
If your most troublesome pans remain in the handwash group, decide whether washing the smaller items would still help enough. Use the running-cost calculator below only after making your own cycle-frequency assumption; this planner cannot convert a dish count into loads, money saved or time saved.

Build a complete purchase budget
| Cost | What to check |
|---|---|
| Appliance | The exact model, seller, item condition, delivery and taxes shown at checkout. |
| Setup | Whether the supplied hoses and connection parts suit your kitchen. Do not buy adapters until compatibility is established. |
| Running supplies | Dishwasher detergent and any rinse aid specified in the manual. Follow the dose for the compact machine. |
| Utilities | Your water and electricity rates, cycle choice and frequency. Rated wattage alone does not establish energy used per wash. |
| Space | The preparation surface you give up, and whether cooking still works comfortably. |
Calculate monthly and annual running costs
Start with the Danby manual’s Normal-program example of 0.36 kWh and 10.8 liters per cycle, or enter documented consumption for your own model and program. Then enter your utility rates and detergent cost. The defaults are an illustration, not a household measurement or a forecast.
Use the variable rates on your bills. Enter 0 for a cost that does not apply. Change consumption, rates or cycle count, then calculate again to refresh the estimate. Use kWh per cycle, not the appliance’s rated wattage.
Where do I find the consumption and rates?
Use the energy and water figures for the exact program in your model’s manual. Rated watts describe power, not total energy for a wash. A tank’s capacity is not automatically the cycle’s total water use. For electricity, enter dollars per kWh. For water and sewer, combine the variable charges and convert them to dollars per 1,000 US gallons; exclude fixed monthly service fees.
For detergent, divide the pack price by the number of usable doses at the dose your dishwasher manual permits. This does not assume every pod fits every compact machine. The annual estimate simply repeats your entered monthly routine twelve times.
Excludes purchase, repairs, setup, fixed utility charges and any separately heated inlet water. No savings versus handwashing are assumed. Your inputs stay in this browser. Source: Danby manual dated September 28, 2021, printed page 9.
Why Danby’s water figures need a qualification
The Danby manual’s Normal-program table lists 10.8 liters and 0.36 kWh. Danby’s product page instead states 11.7 liters / 3.1 US gallons. We cannot establish the reason for that difference. These are published figures, not our household measurements.
Use the manual value as an explicit calculation assumption, not an exact forecast. The difference is 0.9 liter per wash: about 4.76 US gallons over 20 cycles. At $10 per 1,000 gallons, that changes the water-and-sewer example by roughly five cents a month. Electricity, detergent and the number of loads remain separate inputs.
Put a value on your own time
As a planning example—not a measured product claim—if you personally spent 15 fewer minutes washing by hand on 20 evenings each month, that would be 5 hours. Your result could be very different once loading, filling, unloading and leftover handwashing are counted.
That exercise makes the decision personal. A machine does not need a flashy feature list to be useful if it reliably takes the chore you dislike off your hands.
Choose the routine before choosing the offer
The HAVA tank option is worth exploring if you want to avoid a faucet supply connection. The shorter Danby is worth exploring if height is the constraint and its larger footprint works.

Choose the right detergent format
A pack’s purchase price is only one part of detergent cost. Our guide explains how to compare cost per usable wash without assuming every pod or dose suits every model. Read the detergent guide →
