FAQ
How Accurate Are the Calculator Results?
Our calculator uses precise mathematical formulas for compound interest calculations. However, actual investment returns may vary due to market conditions, fees, and other factors not accounted for in this simplified model.
What's the Difference Between Beginning and End-of-period Deposits?
Beginning-of-period deposits are made at the start of each period and earn interest for the entire period. End-of-period deposits are made at the end and don't earn interest until the next period. Beginning-of-period deposits will require slightly lower amounts to reach the same goal.
Should I Choose Monthly or Other Deposit Frequencies?
Monthly deposits are often most practical for budgeting purposes and align well with salary payments. However, the calculator allows you to explore different frequencies to find what works best for your situation.
How Do Annual Deposit Increases Work?
Annual increases allow you to account for inflation or growing income. For example, a 3% annual increase means your deposits will grow by 3% each year, helping maintain purchasing power over time.
