Chapter 281 Learning from the Goblin

"It'll be easier if you know." Rogge smiled and said, "Gringotts' loan interest rate is 10% to 15%, and it's compound interest."

Somehow, Filch couldn't help but appear in his mind. That poor administrator actually signed up for some unknown magic crash course last year and borrowed 10 Galleons from the goblin.

It's so ridiculous that even Dumbledore couldn't make the Squib learn magic. How can a low-level magic class solve it? If they really had the ability to turn Squibs into wizards, they wouldn't just hold a training class, but directly apply for the Order of Merlin.

The goblins in Gringotts are even more of a group of cold-blooded moneylenders. They never care what the borrower does with the money. As long as the other party signs the loan agreement, everything will be fine.

The monthly interest rate was 15%, compounded, and Filch signed the offer without hesitation. Six months later, however, he gave up on the correspondence course.

So, he found Rogge and wanted to ask him to help calculate the debt he owed. When he heard that the interest alone reached 13 Galleons, Filch almost fainted on the spot.

Rogge curled his lips, even if the magic crash course was real, it could turn Filch from a squib into a wizard. He does not have the magic power to turn stone into gold, and it is impossible for him to turn gold into gold out of thin air to repay his debts.

Of course, as Filch's friend, Rogge was happy to give generously. Provide him with some trivial help, such as a few dozen galleons.

He looked at George and Fred with a huge smile on his face. Just like the goblins of Gringotts seeing high-quality customers, they are full of affinity.

"8% monthly interest, compound interest calculation." Roger laid out his conditions and stared at George and Fred to observe their reactions.

"8%..." The two brothers looked at each other. They were not sure whether the interest rate was high or low.

After all, for most wizards, their knowledge of mathematics is limited to arithmetic classes. For complex calculations involving decimal points and compound interest, you can only turn to the goblins of Gringotts.

"In other words, the daily interest rate is less than three thousandths." Rogge played a word game and bullied the wizards for their poor math.

If the limited time is divided into infinite subdivisions, even if you leave nine times and return home thirteen times, it will still look very conscientious and reasonable.

"Is this interest rate too low?" Malfoy frowned and quickly advised Rogge: "Gringotts' loan interest is at least 10%! Rogge, how can you give them 8%? Don't forget, they are Weasley, or Gryffindor."

Seeing Malfoy so excited, the twins, who were already a little undecided, immediately understood that the interest rate offered by Rogge was not high.

George and Fred looked at each other and immediately agreed to Roger's condition: "8% is 8%, we will definitely pay it back."

"Monthly interest is still compound interest, don't forget this." Rogge asked Gower to find parchment and quills, and the two brothers must sign the agreement on the spot.

He couldn't help but cheer Malfoy's anger inwardly. Calculated based on compound interest, the interest in the first year was 48 galleons, which far exceeded the principal. Two years later, the interest was as high as 171 Galleons.

They want to pay back the money within the next two years, unless they can get funding or charity from others. The longer it goes on, the more money they owe.

Seeing George and Fred happily signing the repayment agreement, even with Roger's always calm expression, he couldn't help but smile.

He secretly lamented that the goblins in Gringotts were really ruthless. They can actually offer 15% monthly compound interest, and they are not afraid that borrowers will be unable to repay, causing them to lose everything.

Of course, the monsters do not agree with Rogge's ideas. They have their own logic. In their view, wizards in the magical world are not high-quality customers, so they need to hedge their risks through high interest rates.

As long as one account is recovered, the loopholes caused by other bad debts can be eliminated. Besides, not every bad debt goes to waste.

Roger took the quill from George's hand and signed his full name in cursive script. Finally, he stamped the ring on the agreement, leaving a clear family emblem. With it, the validity of the agreement can be proven.

"So formal? As for it?" Fred muttered softly.

Before the two left, they shouted at Rogge and others: "We will definitely pay back the money!"

Rogge smiled but said nothing, looking forward to the Weasley twins continuing their efforts.

Working people, working souls, working people are all superior to others. If you don't work hard, how can you make money for me?

Rogge looked at the backs of Gemini and silently cheered for them in his heart: "You must work hard and pay back double the money."

"Goyle, aren't you going to Hogsmeade at the end of October?" Rogge said, throwing the Gemini money bag to him, "Help me invite the whole school to Honeydukes to eat candy."

Gore quickly took the money bag and said in disbelief: "Roger, is it true?"

Feeling the heavy weight of the gold galleons, he imagined how many candies he could buy. Lemon sorbet, licorice wand, cockroach pile, ice mouse...

Foodie Gao Er couldn't help but swallow his saliva when he thought of this. He said: "But more than 30 Galleons is too much, I can't use it all~"

"If you can't use it all at once, please ask for it a few more times." Rogge patted Gower on the shoulder and asked him to figure it out.

Anyway, with the Weasley twins as working-class workers, they will soon earn back the money for Rogge.

"Oh, I want to go to Hogsmeade too!" Malfoy looked at Goyle unwillingly, hugged his neck and shook him, sighing: "You must bring me some candies from Honeydukes' house. I want bloody lollipops and pepper naughty boys..."

Malfoy said a lot of things, but Goyle didn't remember the last one. He could only use a stupid method to buy all the candies from Honeydukes family and bring them all to Malfoy.

There is still some time before the end of October, and the third grade students can only look forward to that day.

According to previous years' practice, everyone needs to submit the consent form to their respective dean before Halloween. Without the signature of a parent or guardian, these students can only stay in school and cannot go out.

Harry should thank Malfoy and the Weasley twins. If they hadn't fought, he would have been the only one forced to stay at school at the end of October. Of course, it is also possible to go with the team to other schools to participate in secondary leagues.

Now, players from Slytherin and Gryffindor have been suspended, including Wood, who graduates next year.

Rogge learned from Draco that Dumbledore had spoken to their parents. Privately, Draco also received praise from his father Lucius. If he can not fall behind in one versus two, it means he has won.

The students at Hogwarts were discussing the recent events, and more people were speculating whether they would win or lose tomorrow's first game.

Harry was taken back to his office by Lupine, and it took a lot of effort to break the petrification spell. Wiping the sweat off his head, Lu Ping began to wonder if his strength had deteriorated, as he could not even lift the petrification spell.

Harry sat on the steps and stared at Lupine with burning eyes: "Professor, are you really a friend of my parents?"

Lupine nodded, then sat next to him and began to talk about his relationship with James, Lily and others. Harry finally smiled when he heard about the prank they had played on Snape.

Lupine recalled: "We were still students at that time, and Snape always liked to show off his potions skills, which made us think he was annoying."

"We tied him to the stadium flagpole and poured a whole bottle of soapy water into him. No matter whether he was breathing or talking, bubbles would come out of his mouth and nose. At that moment, we were all laughing."

Snape's dark history seemed to be an antidote for Harry to temporarily forget about Sirius and the wand. He couldn't wait to ask Lupine, wanting to know what else they had done to the annoying Snape.

When he heard about James hanging Snape upside down after the OWLs exam, Harry even held his stomach and laughed.

He vividly imagined Snape's embarrassment at that time, being hung upside down in the air by his father's magic, and his greasy hair had to hang down.

Snape struggled, trying to free himself from the magic, but to no avail. He couldn't even take out his wand to fight back, so he could only let everyone laugh at him and become the laughing stock of the campus.

Lupine continued to tell some interesting school anecdotes about Snape, including some things like taking off his pants in public. The two of them burst into laughter, and these relaxing memories made Harry cherish the professor in front of him who had spent his youth with his parents even more, and felt more cordial in his heart.

Now, Harry understood what happened to him in Potions class. It turned out to be Snape's revenge for the prank he suffered back then. Lu Ping also agreed with this point.

The man called Bat by the students was a Death Eater who betrayed the wizarding world and joined Voldemort. If it weren't for Dumbledore's bail, he should have stayed in Azkaban instead of being a professor here.

During the conversation, the two felt more and more in tune with each other. Harry even talked about his various experiences since entering school. As the topic deepened, it eventually returned to the sensitive topic of Sirius Black.

"Professor, can you help me?" Harry looked at Lupin, his eyes full of hope.

Lupine pondered for a moment and then said: "I can't help you get your wand back."

Harry lowered his head in disappointment, he had thought of all options. In the end, he was kicked off the flying broom because he didn't have a wand. He is really unwilling!

"However, I can teach you to cast spells without a wand."

"Wandless casting?" Harry jumped up suddenly and stared at Lupin with burning eyes.
