| Group | Base Year | Current Year | p1q0 | p0q0 | |
| p0 | q0 | p1 | |||
| Food | 132 | 10 | 170 | 1700 | 1320 |
| Clothing | 154 | 12 | 160 | 1920 | 1848 |
| Fuel and Lighting | 164 | 20 | 180 | 3600 | 3280 |
| House Rent | 175 | 18 | 195 | 3510 | 3150 |
| Miscellaneous | 128 | 5 | 120 | 600 | 640 |
| Total | – | – | – | 11330 | 10238 |
`sum"p"_1"q"_0` = 11330, `sum"p"_0"q"_0` = 10238
Now, by aggregate expenditure method,
CLI = `(sum"p"_1"q"_0)/(sum"p"_0"q"_0) xx 100`
= `11330/10238 xx 100`
= 110.67
