Does the army match a certain percent with the TSP?

If you are enrolled in the Blended Retirement System, yes. If you're legacy retirement, no. But TSP is still a great retirement vehicle because it's almost free of maintenance fees and you can borrow from it without penalty

Yes and I would recommend pitching in the percentage from your paycheck the military will match. It’s free money. If you are in the reserves/guard then I would also recommend throwing in up to what your employer will match for your retirement. I would also suggest taking extra and putting it into a Roth IRA because it’s tax free when you pull it out. I always increase my retirement contributions to my Roth when I get a step raise in the VA or in the military when I get a promotion.

Compounding interest is one of the most powerful things in the world.

I will give you 3 good reasons to invest in TSP.
- You are investing for the future.
- The government will match some of your contributions. That is free money.
- It can reduce your taxable income.
