Why This Matters

The average household spends over €2,400 per year on energy bills — and most of that money is literally going out the window. Poor insulation, inefficient appliances, and outdated heating systems waste 30-50% of the energy your home consumes.

Energy upgrades are some of the best investments you can make. Unlike home renovations where ROI is uncertain, energy savings are predictable and compound over time. A €500 insulation upgrade that saves €150 per year pays for itself in just over 3 years, then keeps saving you money for decades.

The key is knowing which upgrades give you the best return for your specific situation. A well-insulated home benefits less from more insulation but might benefit greatly from solar panels. This calculator helps you prioritize based on your current bills and home characteristics.

Frequently Asked Questions

How accurate are the savings estimates?

Estimates are based on industry averages and may vary by 20-30% depending on your climate, energy prices, home construction, and usage patterns. Use them as a guide for comparing options rather than exact predictions.

Which upgrade has the best payback?

LED lighting and smart thermostats typically have the fastest payback (under 2 years). Insulation upgrades pay back in 3-5 years. Solar panels take 7-12 years but offer the largest long-term savings. Heat pumps vary widely by climate.

Does the calculator account for energy price increases?

Yes. The projections assume annual energy price increases of 3-5%, which means savings grow over time as the cost of energy you're avoiding increases each year.

Can I combine multiple upgrades?

Yes! Select multiple upgrades and the calculator shows combined savings. Note that some upgrades interact — insulation reduces the savings from a heating upgrade since you're already using less energy.
