Depending on the size of your home, number of persons living and your food preferences, your needs in capacity of certain appliances may differ. A double door fridge will consume 30-40% more power than a single door fridge. The larger the volume of the fridge the more is its power consumption. Also, using a multi-cooker saves electricity, as it heats all around the pot, rather than just under as an electric stovetop does.
Investments will be lower, but you should consider your actual needs.
