How this calculator works

For each start year, we apply the year-by-year total return of the Bloomberg US Aggregate Bond to the entered starting amount, compounding annually with dividends reinvested at year-end. This mirrors what an actual buy-and-hold AGG holder would have experienced, before fees and taxes. Expense ratio is intentionally excluded from the historical result to keep the underlying series comparable across ETFs; for a full lifetime fee estimate at 0.03%, use the projection tab in our fund fee analyzer.
