The Power of Compounding in Nigeria
Starting early is the single most powerful action you can take. Investing ₦50,000/month from age 25 to 65 at 15% p.a. builds roughly ₦4.8 billion. Starting at 35 with the same amount builds only ₦980 million — a difference of over ₦3.8 billion for just 10 years of delay.
Rule of 72: Divide 72 by your annual rate to estimate years to double. At 15%, your money doubles every ~4.8 years. At 20%, every ~3.6 years.
Remember: Nigerian inflation (currently ~22%) erodes purchasing power. Always target returns above inflation for real wealth growth.
