How this calculator works
- The tool compares the electricity used per drying cycle by the two appliances at the unit rate you enter.
- That per-cycle saving is multiplied by the number of loads you expect to dry each week.
- The extra purchase price is then divided by the annual energy saving to estimate simple payback.
What can change the result
- Loads dried each week
- Comparable energy use per cycle
- Electricity price
- The actual purchase-price premium
How to read the result
Frequent users usually recover an efficiency premium faster. If you dry only occasionally, purchase price, features and expected appliance life may matter more than the energy saving.
A useful way to stress-test the answer is to change the most uncertain input by 10 to 20% and see whether your decision still looks sensible.
Worked example
A household doing seven loads a week can recover the premium much faster than one doing two.
Frequently asked questions
