No, it's not to you, it's to banks.
You will still get the same interest you did on your savings account.
By offering negative interest rates to bank you are encouraging banks to offer loans at low rates.
So when I, the ECB, give you, the bank, a loan at NO INTEREST, I'm giving you a chance to make money on my terms. So I'll give you 10mil euros with no interest means that 10 years from now, you'll still have to pay me back just the 10mil euros. You can do nothing with that money and you'd lose or win nothing over those 10 years. Ofc, I, the ECB, tell you to loan those 10mil euros at low interest to people who wanna... I don't know, buy cars. It's basically a stimulus to the car industry. So I tell you to loan all that 10mil euros at 1% interest to people who wanna buy cars. At the end of the day, you make money and when you have to pay me back, you'll have earned something. Better than earning nothing because when you try and give loans to people who wanna buy cars are 5% interest, they don't take them. In reality, it's a stimulus to the car industry, a subsidy basically and a way to make some of my banker friends richer.
But when I give you negative interests, I, the ECB, will tell you : take 10mil euros, loan it the way I tell you to loan it (say, for start-up businesses and the interest at 0.5%) and I'll pay you a 0.1% of the value of the loan for 5 years. So you'll be making money from the 0.5% interest that you get from people who wanna do start-ups and the 0.1% from me and 10 years from now when you give me back the 10mil euros, you'll have made a bunch of money.
Now ofc, I, the ECB, in order to give you the 0.1% of the total value in negative interest, I have to print out money. Which means deflation. which means the euro goes down in value. Because the euro is a strong currency and has just 0.5% inflation as opposed to say, the dollar which has a 2% inflation rate .

I will effectively make the euro less valuable in contrast to other currencies. Which is both good and very, very bad. It's going to be a kick in the nuts to heavily indebted countries that owe debt to non-EU countries. Why non-EU countries? Because as it's been seen, with countries like Greece and Portugal, it's been something called "restructuring of debt" in the EU which basically was an adjusting of the debt levels of the EU to not be ****ed by rate of the euro.
So what the ECB is trying to do get the euro at a 0.7% inflation rate. Which again, it's good and bad. Most countries agree on a 1.5-2.5% inflation rate to be optimal.
