The fundamental equation of
finance: |

ROW/COL |

F |
G |

I |

|
The compound amount
equation is: |
|
8 |
|
V = P *(1+ i)^t |
|
9 |
|
|
10 |
|
|
11 |
|
|
12 |
|
13 |
This equation can also be
stated as follows. |
|
14 |
|
ln(V )=
ln(P)+t*ln(1+ i) |
|

|
|

|
I = |

|

|
P = |
$100.00 |
|
22 |
|
t = |

|
23 |
|
24 |
|
ln(v)= |
5.558272 |
<=LN(D21)+D22*(LN(1+D20)) |
|
25 |
|
26 |
|
V = |
$259.37 |
<=EXP(D24) |
|
27 |
|
28 |
|
Using the FV function |
$259.37 |
<=FV(D20,D22,0,D21)*-1 |
|
29 |
|
30 |
|
An alternative would be: |
|
31 |
|
32 |
|
33 |
|
ln($1.00
)=t*ln(1+ i) |
|
34 |
|

P = |

|
t = |

|
42 |
|

|
ln(1)= |
0.9531018 |
<=D41*(LN(1+D39)) |
|

|
FV Factor |
2.5937425 |
<=EXP(D43) |
|

|
For |
$100 |
|
|
47 |
|
V= |
$259.37 |
<=+D44*100 |
|
48 |
|
49 |
|
50 |
|
Another
alternative for annual compounding would be: |
|
51 |
|
52 |
|
53 |
|
V=P*exp(t*ln(1+
i)) |
|
54 |
|
|
55 |
|
|
56 |
|
|
57 |
|
58 |
|
I = |
10.00% |
|
59 |
|
P = |
$100.00 |
|
60 |
|
t = |
10 |
|
61 |
|
62 |
|
V= |
$259.37 |
<=+D59*EXP(D60*(LN(1+D58))) |
|
63 |
|
64 |
|
For continuous
compounding the formula would be: |
|
65 |
|
66 |
|
V=P*exp(t*i) |
|
67 |
|
|
68 |
|
|

|
|

|
|
|
|

|
I
(continuously) = |
10.00% |
|
72 |
|
P = |
$100.00 |
|
73 |
|
t = |
10 |
|
74 |
|
75 |
|
V= |
$271.83 |
<=+D72*EXP(D73*D71) |
|
76 |
|
77 |
|
78 |
|
Note the difference of |
$12.45 |
<=+D75-D62 |
|
79 |
|
is caused by the
frequency of compounding |
