Allocations as of October 25, 2026. Current models are published monthly. A new publication doesn't always mean the percentages have changed.
You can compare these percentages with your current TSP investments or use them as a reference when considering your own mix. If you decide to follow this model, you make the account changes yourself.
Consider whether the allocations fit your timeline, comfort with risk, and other retirement resources. A matching year alone doesn't tell you whether a model is right for you.
If you choose to follow the model, sign in through the official TSP website and use the published fund percentages. Check the current TSP instructions for the changes you want to make.
Before submitting, confirm that your percentages total 100% and that you're changing what you intend: your existing balance, future contributions, or both.
aVectors is designed for portfolio reviews at least quarterly. Current models are published monthly if you want to follow each update.
Compare the latest percentages with your current allocation and consider whether your needs have changed. Reviewing doesn’t automatically mean making a change.
Each portfolio uses a different methodology and glide path, which results in different allocations across the TSP funds. These differences can affect risk and return.
See the published year-to-date returns alongside a hypothetical growth of $10,000.
The hypothetical growth illustration is not an actual TSP account. Your results may differ because of contributions, withdrawals, and when you make changes. Past performance does not guarantee future results.
aVectors studies target date funds from established investment companies, including active and index-based approaches. Selected fund families help shape the model, which uses only TSP funds.
The models run twice weekly, results are reviewed regularly, and current allocations are published monthly.
