Drop in a paystub, bank statement or screenshot — the AI reads it and fills these fields for you.
Portfolio Tracker is where this stops being a one-off number: keep your real balances there and the projection updates itself.

APR and APY often describe the same product from different angles. The FDIC Truth in Savings overview treats APY as the disclosure rate that reflects interest and compounding for deposit accounts.
Use the same compounding frequency stated in the product terms. A daily APY and monthly APY are not interchangeable.
When comparing accounts or protocols, compare APY to APY. APR can understate the effective return when rewards compound.
If the underlying rate changes, the projected APY changes too. Treat high APYs as a snapshot, not a promise.
APY is the cleaner comparison metric because it includes compounding. APR is useful, but only tells part of the story.
