Assumed annual return
Hypothetical illustration. Not a prediction. Actual returns vary and you can lose money.

Assumes a constant 10% annual return compounded weekly, with no fees, taxes, or missed contributions. VOO's trailing 10-year annualized total return was approximately 15.5% as of August 2026, a period of unusually strong market performance. The S&P 500's long-run historical average is closer to 10%. Past performance does not guarantee future results. Investing involves risk, including possible loss of principal. Reward estimates are approximations based on the inputs above and will differ from your actual rewards. GrowFi does not redeem or access your credit card rewards. The invested amount is debited from your linked checking account. This is not investment advice.
