How can I properly calculate the PV, EV, CV, SV, CPI, and SPI? I am getting incorrect values. See attached for the planned duration, actual duration, planned budget, and actual cost.

Planned Duration	Actual Duration	Difference	Budget	Actual	Difference	PV	EV	CV	SV	CPI	SPI
14	14	0	$2,100	$ 2,100.00	$0.00
15	18	3	$ 4,500.00	$ 5,400.00	$900.00
8	13	5	$ 2,400.00	$ 3,900.00	$1,500.00
5	20	15	$ 1,500.00	$ 6,000.00	$4,500.00
10	10	0	$2,000.00	$2,000.00	$0.00
9	15	6	$ 1,800.00	$ 3,000.00	$1,200.00
