The installation price is the beginning of the budget. Electricity, water, routine care and eventual repairs shape the cost of ownership. Here is how to estimate those items without relying on a promised annual figure.

Separate construction from ongoing costs
Use the price and package page for the advertised starting investment and scope. The budget here concerns what happens after construction. There is no single annual operating cost that reliably describes every natural pool: equipment, operating plan, optional features and how much work you do yourself all matter.
Ask for an ownership estimate alongside the proposal, with its assumptions written down. Keep electricity, water, care products, paid service and future repairs as separate lines. That makes it easier to see whether a low total leaves something out, and to replace an estimate with measured information after the first season.
Calculate electricity from input power and time
The Swedish Energy Agency explains the calculation: power in watts multiplied by operating hours gives watt-hours; divide by 1,000 for kilowatt-hours. For a cost estimate, multiply those kilowatt-hours by the relevant electricity cost per kilowatt-hour.
Use electrical input power, not a pump's water flow or a heater's heat output. A manufacturer's figure must correspond to the actual model and operating setting. For variable equipment, measurements over representative use are more helpful than assuming that the maximum rating applies all day. Ask the installer how consumption can be measured safely; do not introduce an unsuitable meter or extension lead around water.
A worked example with hypothetical assumptions
This example describes one imaginary electrical load. It is not a Faunapoolen package specification, a recommended operating schedule or a quoted electricity tariff. Assume a constant input of 100 watts, operation for 24 hours a day over 180 days, and a variable electricity cost of SEK 2.00 per kilowatt-hour excluding VAT.
Calculate this load's cost: 432 kWh × SEK 2.00/kWh = SEK 864 for the stated period.
At an assumed SEK 3.00 per kilowatt-hour, the same 432 kWh would cost SEK 1,296. Both figures exclude VAT and cover only that load and period. Add every actual component and any operation outside the example period. Lighting, additional circulation or heating, if part of the design, need their own entries.
Replace the example price with the relevant variable charges from your supply and network agreements, excluding VAT consistently. Fixed charges and any demand-based network charge are outside this simple multiplication. Check your provider's billing model before attributing a change in the household bill to the pool.
For warmer water and a longer season, our nature pool heating guide explains what affects the heating budget.
Budget for water using volume
Keep the initial filling separate from later top-ups and water used during maintenance. Ask how volume will be estimated or recorded, then use the applicable local water tariff, including any wastewater charging that actually applies. If water must be delivered, obtain a separate delivery price rather than using the municipal rate.
Do not assign an automatic full refill to every year, or assume that no further water will be needed. Follow the system's care plan and investigate unexplained losses. Our permissions and water-planning guide explains why filling and disposal arrangements need local confirmation.
Include your time and the work you will buy
Decide which routine tasks you want to do and which you would prefer to arrange with a service provider. Ask for a description of a visit, its price and what is excluded. Travel, consumables or replacement parts may be separate; a service price is only comparable when the scope is clear.
List care materials and tests specified for the actual installation, without assuming every system uses the same products. Our seasonal care guide helps organize the work. Reducing required circulation or postponing necessary care is not a reliable cost-saving plan.
Leave room for replacement and review
Ask about warranties, serviceable parts and replacement options for the proposed equipment. A repair reserve is a budgeting choice, not a claim that every pump fails after a fixed number of years. Keep it separate from routine operating costs so the annual comparison stays understandable.
