Core Move: $25,000 Placed in SoFi on August 20, 2026
On August 20, 2026, the author transferred $25,000 into a SoFi Checking and Savings account. The app displayed a 3.80 % APY, indicating that the balance would generate $950 in interest over a full year, or $79.17 each month if the rate remained unchanged.
Account Terms and Conditional Yield
The advertised 3.80 % APY is a limited-time boost of 0.70 % that lasts for up to six months. After the promotional window, the rate reverts to a 3.10 % base APY.
To retain the 3.80 % rate, the account must receive either an eligible direct deposit or at least $5,000 in qualifying deposits every 31 days. Missing this requirement causes the APY to drop to the lower base tier. The account carries no minimum balance, no monthly service or maintenance fees, and funds remain same-day liquid. FDIC insurance is provided through SoFi Bank, N.A. up to standard limits.
Calculating the Expected Earnings
Because APY already incorporates compounding, the straightforward calculation is:
- $25,000 × 3.80 % = $950 annual interest, or $79.17 per month, if the promotional rate persisted for twelve months.
No additional compounding adjustment is required; the daily balance and monthly credit already align with the stated APY.
Blended Annual Yield After the Promo Period
The six-month promotional rate and the subsequent six-month base rate produce a blended yield:
- Six months at 3.80 % -> $475 interest
- Six months at 3.10 % -> $387.50 interest
Total twelve-month interest = $862.50, which corresponds to an effective blended APY of 3.45 %.
Comparison with National Savings Benchmarks
According to FDIC data as of August 1, 2026, the national average yield on a 12-month CD is 1.71 %, and the average passbook savings rate is considerably lower. Even after the promotional period ends, SoFi’s 3.10 % base APY (or the blended 3.45 % over a year) outperforms these averages by a wide margin, while offering the liquidity of a savings account rather than the fixed term of a CD.
Timeline of Key Dates
- August 20, 2026 – $25,000 deposited into SoFi account (3.80 % APY).
- August 1, 2026 – FDIC reports national average 12-month CD yield of 1.71 %.
What’s Next: Ongoing Rate Requirements
Maintaining the promotional 3.80 % APY requires meeting the $5,000 qualifying deposit threshold each 31-day cycle. Failure to do so will shift the account to the 3.10 % base rate for the remainder of the year. No further scheduled changes are disclosed.
