Many people are hesitant to use dishwashers because they worry about "high electricity, water, and tablet costs." In reality, the monthly cost is less than you think—let's break it down.
3 costs when using a dishwasher
Costs include: (1) chemicals (dishwashing tablets + salt + rinse aid), (2) electricity, (3) water. Chemical costs are the easiest to calculate.
Chemical cleaning costs
Calculated per wash for a full load of dishes:
| Product | Cost/wash |
|---|---|
| Largo Classic 60 tablets | ~3,817 VND |
| Largo All-in-one 40 tablets | ~5,475 VND |
For families washing 1 load/day, the tablet cost is only about 115,000–165,000 VND/month. Salt and rinse aid last a very long time (a 1L rinse aid bottle lasts 200+ washes), so the monthly cost is negligible.
Electricity and water
This cost depends on the machine and local electricity prices, but it's usually modest. Notably: newer dishwashers often use less water than washing by hand for the same amount of dishes, so the water consumption isn't as high as many people fear.
Monthly total
In total, the monthly operating cost for a family is usually only a few hundred thousand VND — in return, you save an hour of handwashing every day and your hands are no longer dry and rough.
How to optimize costs
Using Classic tablets + salt + rinse aid is the cheapest way for each wash. Buy a saving combo for the best price.
