Forecast April 1,240
Alpha 0.20
| Period | Actual [A(t)] | ||
| March | 1210 | ||
| April | 1280 | ||
| May | 1260 | ||
| June | 1275 | ||
| F(t) = | F(t-1) + α [A(t-1) - F(t-1)] | ||
| Period | Exponential Forecast | [F(t)] | |
| F(t-1) + α [A(t-1) - F(t-1)] | |||
| April | Given | = | 1240 |
| May | 1240 + 0.20 [1280 - 1240] | = | 1248 |
| June | 1248 + 0.20 [1260 - 1248] | = | 1250 |
| July | 1250 + 0.20 [1275 - 1250] | = | 1255 |
| Therefore, As per the Exponential Forecast, Sales for July is 1255 | |||
