About This Compound Interest Calculator
This calculator supports different compounding frequencies and contribution frequencies (daily, weekly, monthly, quarterly, semi annually, or yearly). It computes how your initial balance, plus periodic contributions, grows with compound interest over the specified number of years.
Key Steps:
- 1. We find the least common multiple (LCM) of the compounding frequency and contribution frequency.
- 2. That number of “sub-periods” per year ensures we accurately handle cases where contributions and compounding occur on different schedules.
- 3. Each sub-period adds interest based on a portion of the annual rate, and adds a contribution at intervals aligned with the contribution frequency.
