Usage Notes

SYD Calculation
The SYD function calculates the depreciation as follows:

1) The asset begins with a value of $100,000 in Year 0 and ends up with a value of $15,000 in Year 5, producing a loss of $85,000 in value over the period.

2) Depreciation in Year 1 is calculated by 5/15 * 85,000 = 28,333; Year 2 is calculated by 4/15 * 85,000 = 22,667, etc.

3) Excel finds the denominator by summing the years as follows: =1+2+3+4+5 = 15.
