BRS vs Legacy Retirement: Which One Pays More?
2026 Rates
The great military retirement debate: Does the Blended Retirement System (BRS) or the Legacy High-36 pay more? The answer depends on how much you contribute to TSP and how long you serve.
Legacy (High-36)
- Pension Multiplier2.5% per year
- At 20 Years50% of base pay
- At 30 Years75% of base pay
- TSP MatchNone
- Continuation PayNone
- VestingAll or nothing at 20
- Lump Sum OptionNo
Blended Retirement System
- Pension Multiplier2.0% per year
- At 20 Years40% of base pay
- At 30 Years60% of base pay
- TSP MatchUp to 5%
- Continuation Pay2.5-13x monthly pay
- VestingTSP vests at 2 years
- Lump Sum OptionYes (25% or 50%)
The Key Trade-off: Legacy gives 50% pension vs BRS's 40%, but BRS adds TSP matching that can close or exceed the gap if you invest it well.
Scenario: E-7 at 20 Years
High-36 average: $5,789/month | TSP contribution: 5%
Legacy
$2,895
Monthly pension (50%)
Annual: $34,734
TSP at 60: ~$152,000*
Total at 60: ~$846,000
BRS
$2,316
Monthly pension (40%)
Annual: $27,787
TSP at 60: ~$304,000*
Total at 60: ~$860,000
*Assumes 7% annual return, retirement at 38, withdrawing at 60. TSP match doubles BRS contributions.
How TSP Changes the Math
The winner depends heavily on your TSP contributions:
| TSP Contribution | Legacy TSP at 60 | BRS TSP at 60 | Difference | Winner |
|---|---|---|---|---|
| 0% | $0 | ~$152,000 | +$152k | BRS (but pension lower) |
| 5% (match) | ~$152,000 | ~$304,000 | +$152k | BRS |
| 10% | ~$304,000 | ~$456,000 | +$152k | BRS |
| 15% | ~$456,000 | ~$608,000 | +$152k | BRS |
The math is clear: At any TSP contribution level, the 5% match gives BRS members $152,000+ more in TSP by age 60 (assuming 7% returns). This often more than makes up for the 10% lower pension.
When Legacy Wins
Legacy can still be better in specific scenarios:
- You don't invest TSP wisely. If you leave TSP in the G Fund (2-3% returns), you miss out on growth that makes BRS worthwhile.
- You serve 30+ years. The gap widens: Legacy pays 75% vs BRS's 60%. The extra $700+/month for life adds up.
- You need guaranteed income. Pension is guaranteed; TSP depends on market performance.
- You live a very long time. Pension pays forever; TSP can run out.
When BRS Wins
- You contribute to TSP. At just 5%, you double your contributions with matching.
- You leave before 20 years. Legacy = $0. BRS keeps your vested TSP match.
- You invest in growth funds. C/S/I funds historically return 7-10% annually.
- You want flexibility. TSP is YOUR money; pension depends on the government.
- You got continuation pay. That 2.5-13x bonus at year 12 is extra compensation.
Lifetime Value Comparison (E-7 at 20)
| Metric | Legacy (High-36) | BRS |
|---|---|---|
| Monthly Pension | $2,895 | $2,316 |
| Annual Pension | $34,734 | $27,787 |
| Pension Age 38-85 (47 years) | $1,632,498 | $1,305,989 |
| TSP at 60 (5% contribution, 7% return) | ~$152,000 | ~$304,000 |
| Continuation Pay (year 12) | $0 | ~$14,500 |
| Total Lifetime Value | ~$1,784,500 | ~$1,624,500 |
Note: This comparison uses conservative 5% TSP contributions. At higher contribution levels, BRS catches up or wins.
