Simple Interest vs Compound Interest

📈 Simple Interest

Interest is calculated only on the principal amount. Interest does not earn interest.

Formula: Interest = Principal × Rate × Time

Example: 10.000 TL, %15 interest, 12 months = 1.500 TL interest

📊 Compound Interest

Interest also earns interest. Provides higher returns.

Formula: Total = Principal × (1 + Rate)^Time

Example: 10.000 TL, %15 interest, 12 months = 1.608 TL interest
