= 53.846.154 + 47.337.579 + 40.973.657 + 35.016.835 + 29.620.422−200.000.000 

= 206.794.647−200.000.000

NPV2 =6.794.647 

Langkah 2: Menginterpolasi untuk Mendekati IRR

IRR berada di antara 20% dan 30%.

IRR ≈ r1+(NPV1/NPV1−NPV2) × (r2−r1) 

Di mana:

• r1=20%
• r2=30%
• NPV1=58,411,902
• NPV2=6,794,647

Menghitung IRR:

IRR ≈ 20% + (58.411.902/58.411.902−6.794.647) × (30%−20%)

IRR ≈ 20%+ (58.411.902/51.617.255) × 10%
