Stack military pension + VA disability against civilian, federal, MBA, or self-employment paths. See the lifetime wealth delta for each scenario.
Deciding whether to stay in the military for another 2, 5, or 10 years — or separate now — is the single most consequential financial choice most servicemembers will ever make, and most make it without numbers. Military total compensation is invisible: an E-7 at 12 years in San Diego earns roughly $52K in base pay but a total package worth ~$127K once you stack BAH, BAS, TRICARE, TSP matching, and the federal tax advantage. Staying to hit 20-year retirement adds a pension that pays $800K–$1.5M+ over a lifetime depending on rank and system (Final Pay, High-3, or BRS). But separating two years earlier means starting a civilian career two years sooner — at a salary premium that compounds. The right answer depends on your rank, years, post-separation path (private-sector career, federal GS job, MBA, or self-employment), VA disability rating (which interacts with retired pay through CRDP/CRSC), and education benefits remaining (GI Bill or VR&E). This calculator stacks all of it.

This calculator builds a lifetime cash-flow model for each scenario (stay to retirement vs. separate now into each of four post-separation paths) and projects total wealth to age 65 and age 85. The "stay" scenario uses 2026 DoD basic pay tables plus BAH (location-averaged), BAS, TRICARE valuation, TSP matching (BRS only), and the federal tax advantage, projecting forward through the years remaining until retirement eligibility and then layering the appropriate retired-pay system (Final Pay for pre-1980 entrants, High-3 for 1980–2018, BRS for 2018+, CSB/Redux where applicable).
Each "separate now" scenario uses the user's stated post-separation income (private-sector salary, federal GS pay including locality adjustment, post-MBA projected salary, or self-employment income net of healthcare swap) and stacks it with VA disability compensation, GI Bill or VR&E monthly subsistence where applicable, and (for the federal path) FERS pension accrual plus military service buyback. The model accounts for the CRDP/CRSC offset on retired pay for veterans rated 50%+ and surfaces the tax-free advantage of VA disability against taxable retired pay or civilian salary.
Lifetime totals assume 2.5% annual COLA on military and federal pensions, 3% annual civilian salary growth through age 65, 7% nominal TSP/401(k) returns, and a 4% safe withdrawal rate on retirement-age portfolio balances. The breakeven year is the point at which the cumulative wealth lines for "stay" and "separate" cross. This is an educational planning tool, not a financial advisory product — actual outcomes depend on promotions, duty stations, market returns, family events, and dozens of other variables this model cannot capture.
There is no universal answer — it depends on your years of service, rank trajectory, post-separation plans, and VA disability rating. Staying to hit 20-year retirement typically pays $800K–$1.5M+ in lifetime pension depending on system (Final Pay, High-3, or BRS), but the opportunity cost of staying 2 more years can range from $80K–$200K in lost civilian earnings. For most servicemembers with 18+ years in, staying is mathematically right unless you're separating for a specific high-paying civilian role or graduate program. For those at 8–14 years, the answer depends entirely on post-separation path.
Lifetime pension value depends on rank at retirement, years of service, and retirement system. An O-5 retiring at 20 years under High-3 receives roughly $5,500–6,500/month (2026 dollars), which over 30+ years of retirement equals $2.4M–$3.5M+ before COLA. An E-7 retiring under BRS at 20 years receives roughly $2,300–2,800/month, equating to $1M–$1.4M lifetime. The Military Retirement Pay Calculator models all four active-duty systems plus Reserve and Guard.
The cost of staying is the gap between projected civilian compensation and military total compensation over those 2 years. For an E-7 separating at 12 years to a $95K civilian job, staying 2 more years for retirement-eligibility tracking means trading ~$190K of higher civilian income for 2 more years of military pay (often roughly equivalent depending on duty station and BAH). For someone at 18 years going to 20, the opportunity cost is real ($150K–$200K in lost civilian salary differential), but the pension unlocked at 20 years pays back in 5–8 years.
Yes — under all four active duty retirement systems, you must complete 20 years of active service to receive immediate retired pay (narrow exceptions exist for medical retirement under Chapter 61). Servicemembers separated involuntarily before 20 years are not eligible for an immediate pension. Reserve and Guard members can build retirement points toward a deferred pension at age 60 (or earlier if mobilized post-January 2008 under Title 10). This calculator surfaces the lifetime cost of separating before retirement eligibility.
VA disability compensation is tax-free. Military retired pay is taxable. Veterans rated less than 50% who receive both must waive an equal amount of retired pay to receive VA disability (the "VA waiver"). Veterans rated 50%+ qualify for Concurrent Retirement & Disability Pay (CRDP), receiving both in full without the waiver. Combat-related disabilities may qualify for CRSC instead. The lifetime tax-advantage of having a high VA rating alongside military retirement can be $500K+ over 30 years.
Yes. The Post-9/11 GI Bill is available for up to 36 months and is valid for 15 years post-separation (extended to lifetime for veterans who separated on or after January 1, 2013, under the Forever GI Bill). VR&E (Chapter 31) is available to service-connected veterans rated 10%+ with an employment handicap; it covers full tuition with no cap plus monthly subsistence. The GI Bill vs. VR&E Optimizer models which benefit is right for your education path.
Federal employment typically pays $15K–$30K less in base salary than equivalent private-sector roles, but stacks unique value most veterans don't know about. Military service buyback under 5 USC § 8334(j) is the highest-leverage move: a one-time deposit of 3% of your military base pay (due within 3 years of federal hire to avoid interest) converts each military year into a 1% FERS multiplier × high-3 salary. For a mid-career enlisted veteran with 10 years of service landing a GS-12 role, that's typically a $15K–$20K deposit adding $10K–$15K/year to the FERS pension for life — roughly a 20–30× lifetime return. For an 18-YOS veteran, the buyback can be the difference between a $23K/yr and a $41K/yr FERS pension. About 80% of veterans entering federal service never make this deposit. Federal employment also includes TSP with up to 5% agency match, FEHB family healthcare carried into retirement, veterans' preference in hiring, and shorter days. The Federal Retirement & TSP Calculator models FERS + TSP + military buyback together.
