📐 Formula for Compound Interest Used
The calculator typically relies on the compound interest formula:
iniCopyEditA = P × (1 + r/n)^(n×t) + contributions compounded over time
Where:
- A = future account value
- P = principal (initial deposit)
- r = annual interest rate (decimal form)
- n = number of compounding periods per year (365 for daily)
- t = time in years
Contributions compound as each deposit earns interest from the time of deposit until the end of the period.
💵 Example Projection
Suppose:
- Initial Deposit: $5,000
- Monthly Contribution: $200
- Term: 5 years
- APY: 3.80%
Estimated Growth:
- Future Balance ≈ $18,000–$19,000
- Interest Earned ≈ $3,500–$4,000
If SoFi’s promotional 4.50% APY applies:
- Estimated Projection exceeds $19,000–$20,000, thanks to the higher rateSoFi.
