If I was in your shoes I would stick with the 1st choice. You dont know what might happen tomorrow. So again stick with the 1st bank but then Im not on your shoes.

Good luck whatever solution you choose

Case 1 - if I don't misread you, you pay 171.

Case 2 - you would have to pay 300.

However, in case 2, you keep more money, much longer. If you reinvest this money and get a good positive interset, case 2 is better, otherwise stick with case 1.

instinctivly i agee with the conclusions of Dorothy and Casuistik

but there is not enough information here ... how long have you been paying off loan 1 ?  

you have four months left at 2500 per month - that means you still have 10,000 chf to pay 

if you are only paying 171 interest - this means you have only been paying it for two months !  really ??   if so and you can afford to pay at this rate stick with it 

(there may be penalites for early exit ) 

if you have been paying for longer and you really do still owe 10k you totally misunderstood your contract

if you cant afford to continue at the rate of 2500 per month you may want to consider switching - but more to spread it longer than to save interest 

it is not as simple as cost - and i dont think you have (or have not given) enough information for anyone to be able to help you 

2500 (+ int.) x 2 = paid

2500 (+ int.) x 4 = to go

6 months = 3.99 % / 2 = 1.995 %

+ int. decreasing = roughly 1.15 % (of the total)

(15000 x 1.15% = 172.5)

Casuistik figured out correct - very smart! Thanks a lot! 

Case 1 - if I don't misread you, you pay 171.

Case 2 - you would have to pay 300.

However, in case 2, you keep more money, much longer. If you reinvest this money and get a good positive interset, case 2 is better, otherwise stick with case 1.

Accurate and smart! It is not for reinvesting, but to help a family member. Case 2 allows transfer from Case 1 only 6000, which should be paid back in total before March 2015. This will relieve my burden to pay back Case 1 in 4 months at bigger amount (over 2500/month). For Case 2, I will pay 500/month to pay off 6000 before March 2015? If I transfer from Case 1 to Case 2, I will save some interest because I will not have to pay for the remaining interest if I pay off the 4000 in total when I do the transfer? I was terrible with percentage learning in elementary school.    

You will have to pay 120.00 to transfer 6k form A to B. Intrests would be about 75.00.

The 18.99 must be outside of Switzerland, as that rate would be exortion here and illegal.

Another way of loking at it:

Case 1: You pay 4% interest for 1/3 year= 1.2% of currently outstanding sum. (In fact less, because the outstanding sum will decrease very rapidly, given that you're so near then end of your term.)

Case 2: You pay 2%

So clearly case 1 is best. (and less hassle.)

Thank you so much! I am quite amazed how knowledgeable and smart you are! Yes, it is outside Switzerland, in fact it is the US. It is credit card rate. The banks are not in Switzerland, either, both are in the US. That's why I can find deals like this. I am torturing myself trying to figure out how to save a little because I have given all my savings to help family members and just temporarily out of money. I make a good salary and expect to pay back soon. That is why I can even think of transferring to the credit card (Bank B) hoping I could pay it all back before the high interest rate starts to kick in. For the moment I still need money to pay several bills. Whatever I can save would help.

I understand the 120, I consider that as the total interest I have to pay for the whole amount to be transferred. But I do not understand the 75 interest - for which part?Tks!
