\(g = {444 \over 464} ≈ 0{,}957 \text{.}\)

Op 1 januari 2025 is de hoeveelheid \(416 ⋅ 0{,}957 ≈ 398 \text{.}\)

Op 1 januari 2023 is de hoeveelheid \({416 \over 0{,}957} ≈ 435 \text{.}\)

Bij de veranderingen horen de groeifactoren
\(g_{1} = (100\% + 2{,}9\%) : 100\% = 1{,}029\)
en
\(g_{2} = (100\% - 1{,}1\%) : 100\% = 0{,}989 \text{.}\)

De totale groeifactor is dan
\(g_{\text{totaal}} = g_{1} ⋅ g_{2} = 1{,}029 ⋅ 0{,}989 = 1{,}017...\)

De totale toename is
\((1{,}017... ⋅ 100\%) - 100\% = 1{,}8\% \text{.}\)

Bij de veranderingen horen de groeifactoren
\(g_{1} = (100\% - 3{,}9\%) : 100\% = 0{,}961\)
en
\(g_{2} = (100\% + 3{,}9\%) : 100\% = 1{,}039 \text{.}\)

De totale groeifactor is dan
\(g_{\text{totaal}} = 0{,}961^{4} ⋅ 1{,}039^{2} = 0{,}920...\)

De totale toename is
\((0{,}920... ⋅ 100\%) - 100\% = -7{,}9\% \text{,}\) ofwel een afname van \(7{,}9\% \text{.}\)

\(g = 8 \text{.}\)

De procentuele toename is
\(8 ⋅ 100\% - 100\% = 700\% \text{.}\)

Bij de verandering hoort de groeifactor
\(g = (100\% + 3{,}6\%) : 100\% = 1{,}036 \text{.}\)

De totale groeifactor is dan
\(g_{\text{totaal}} = 1{,}036^{3} = 1{,}111...\)

De totale toename is
\((1{,}111... ⋅ 100\%) - 100\% = 11{,}2\% \text{.}\)
