Laundry Load Calculator
Estimate weekly and annual laundry loads, wash time, water consumption, and combined detergent and energy cost for your household.
Open toolEstimate per-load and annual laundry cost from supplied use and prices. Provide Electricity per load (kWh), Electricity price per kWh, Water per load (L) to compute results directly in your browser. Same currency; water converted from liters to cubic meters; 52 weeks/year. Excludes appliance purchase, labor and live tariffs. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur.
Enter the inputs, then select Calculate.

Review the input parameters, allowed value ranges, and worked reference cases for the Laundry Cost Calculator below before running your calculation.
| Parameter / Scenario | Default / Sample Value | Rule or Allowed Range | Output / Usage Note |
|---|---|---|---|
| Input: Electricity per load (kWh) | 1 | Range: 0 to 1000000000.0 | Required workspace parameter |
| Input: Electricity price per kWh | 0.2 | Range: 0 to 1000000000.0 | Required workspace parameter |
| Input: Water per load (L) | 50 | Range: 0 to 1000000000.0 | Required workspace parameter |
| Input: Water price per m3 | 2 | Range: 0 to 1000000000.0 | Required workspace parameter |
| Worked Case 1: Baseline run (Electricity per load (kWh) = 1) | Preloaded / test values | Estimate per-load and annual laundry cost from supplied use and prices | Electricity per load (kWh) = 1; Electricity price per kWh = 0.2; Water per load (L) = 50; Water price per m3 = 2; Detergent cost per load = 0.3; Loads per week = 4. The displayed output is Electricity per load: 0.2 Water per load: 0.1 Detergent per load: 0.3 Total per load: 0.6 Annual cost: 124.8. |
| Worked Case 2: Comparison scenario (laundry cost calculator uk) | Preloaded / test values | Estimate per-load and annual laundry cost from supplied use and prices | Electricity per load (kWh) = 0.5; Electricity price per kWh = 0.3; Water per load (L) = 40; Water price per m3 = 3; Detergent cost per load = 0.2; Loads per week = 3. The displayed output is Electricity per load: 0.15 Water per load: 0.12 Detergent per load: 0.2 Total per load: 0.47 Annual cost: 73.32. |
Follow these three steps to configure Electricity per load (kWh), Electricity price per kWh, Water per load (L), verify unit and boundary rules, and export your Laundry Cost Calculator output.
Enter electricity per load (kwh). Allowed range: 0 to 1000000000.0.
Set electricity price per kwh, water per load (l), water price per m3, detergent cost per load, loads per week. Same currency; water converted from liters to cubic meters; 52 weeks/year.
Select Calculate to see the per-load cost components and annual estimate. Copy result copies this text; Download saves it as a TXT file.
These concrete scenarios illustrate how the Laundry Cost Calculator processes baseline inputs, comparison checks, and boundary constraints.
Electricity per load (kWh) = 1; Electricity price per kWh = 0.2; Water per load (L) = 50; Water price per m3 = 2; Detergent cost per load = 0.3; Loads per week = 4. The displayed output is Electricity per load: 0.2 Water per load: 0.1 Detergent per load: 0.3 Total per load: 0.6 Annual cost: 124.8.

Electricity per load (kWh) = 0.5; Electricity price per kWh = 0.3; Water per load (L) = 40; Water price per m3 = 3; Detergent cost per load = 0.2; Loads per week = 3. The displayed output is Electricity per load: 0.15 Water per load: 0.12 Detergent per load: 0.2 Total per load: 0.47 Annual cost: 73.32.

When solving for 'laundry cost calculator', verify that Electricity per load (kWh), Electricity price per kWh, Water per load (L) use consistent units and stay within the documented scope: Same currency; water converted from liters to cubic meters; 52 weeks/year. Excludes appliance purchase, labor and live tariffs. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur.

The output panel reports the exact result derived from Electricity per load (kWh), Electricity price per kWh, Water per load (L) alongside any unit or formatting notes.
The result is the per-load cost components and annual estimate. Combine entered water, electricity and detergent costs.
The annual estimate assumes 52 weeks and your load count; live tariffs are not retrieved.
Numerical output shows up to 12 significant digits. Floating-point arithmetic and display rounding can affect the last digits.

Review these boundary constraints and validation rules before relying on the Laundry Cost Calculator output.
Operational scope: Same currency; water converted from liters to cubic meters; 52 weeks/year. Excludes appliance purchase, labor and live tariffs. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur. Inputs that violate minimum/maximum bounds or required format rules are rejected with a clear diagnostic prompt.
