我正在尝试创建一个电子表格,告诉我何时还清我的贷款。可以说我的贷款是1,500欧元而且我不会支付利息。我每周付款,每周增加2欧元。例如第1周我贷款2欧元,第2周我支付4欧元,第3周我支付6欧元。
根据这个逻辑,我会在一年的第39周获得回报,但是我希望根据我一直保存到的那一周显示我还剩多少个星期。
我还每4周额外支付100欧元
答案 0 :(得分:1)
假设1500贷款,没有利息,每周还款2 x周数(2,4,6,......)和每4周100(所以当周数可以被4整除)。
Loan 1500
Loan repay per week 2
Loan repay per 4 weeks 100
Time Loan at start Regular repayment Adhoc repayment Loan at end
0 1500 1500
1 1500 2 0 1498
2 1498 4 0 1494
3 1494 6 0 1488
4 1488 8 100 1380
...
你被偿还了28周。

26 250 52 0 198
27 198 54 0 144
28 144 56 100 -12
Loan 1500(i.e. B2)
Loan repay per week 2(B4)
Loan repay per 4 weeks 100(b5)
Time Loan at start Regular repayment Adhoc repayment Loan at end
0 =B2 =B8-C8-D8
1 =E8 =$B$4*A9 =IF(MOD(A9,4)=0,$B$5,0) =B9-C9-D9
2 =E9 =$B$4*A10 =IF(MOD(A10,4)=0,$B$5,0) =B10-C10-D10
3 =E10 =$B$4*A11 =IF(MOD(A11,4)=0,$B$5,0) =B11-C11-D11
拖下公式。寻找它消极的地方。
