What calculators do advisors who specialize in federal employees need?

TL;DR. An advisor specializing in federal employees needs, at minimum: a FERS pension calculator (tiered contribution rates, high-3, age-62 multiplier boost), a TSP withdrawal planner, a FEHB/Medicare coordination tool, and a gap-analysis tool that ties them together. AdvisorCal bundles these plus a 6-step Federal Retirement Planner flagship into a single (pricing TBA) subscription designed for this niche.

The five-tool federal stack

Federal retirement planning has five moving parts. A specialist stack covers all five; a generic retirement tool covers none of them well.

1. FERS Pension Estimator. Handles the three contribution tiers (0.8%, 3.3%, 4.4%), the 1% or 1.1% multiplier, the high-3 average, and the FERS Supplement for pre-62 retirees.

2. TSP Withdrawal Planner. Models monthly payments, partial withdrawals, Roth TSP versus Traditional TSP tax treatment, and the G Fund floor that federal employees treat as an allocation anchor.

3. FEHB & Medicare Coordination. Answers the single most common federal-retirement question: "Do I keep FEHB, enroll in Medicare Part B, or both?" The coordination math includes the 2026 Part B standard premium of $206.90/month, IRMAA surcharges for higher incomes, and FEHB premium offsets.

4. Federal Benefits Gap Analysis. Compares the employee's current deductions (FERS, OASDI, Medicare, TSP, insurance) against projected retirement income to quantify the "retirement raise" and surface the income gap between retirement and Social Security claiming.

5. Federal Retirement Planner (the flagship). A 6-step meeting workflow — FERS → TSP → Healthcare → Gap Analysis → Full Report → Download — that produces a comprehensive branded PDF including bridge/sustainability income stages and 5-pillar advisor recommendations.

Why specialists use a purpose-built stack

A federal employee asking a generic tool "how much can I retire on?" gets a wrong answer for predictable reasons. The generic tool doesn't know about the FERS Supplement. It doesn't distinguish Roth TSP from Traditional. It doesn't handle the FEHB+Medicare decision tree. It doesn't know that the employee's current "paycheck" has 5–11% of deductions that stop the day they retire.

A purpose-built federal stack does.

Key facts

Common follow-ups

Can I use these tools with CSRS employees too? CSRS uses a different formula. A federal-specialist stack should indicate CSRS support explicitly. AdvisorCal's current stack is FERS-focused.

Does the stack handle military buy-back? Military service credit deposits (buy-back) affect the creditable-service calculation. The advisor enters post-deposit service years; the calculator uses what it's given.

Do I need a separate tool for Social Security? Social Security is part of the federal-retirement picture. AdvisorCal includes a standalone Social Security calculator alongside the federal stack so the advisor can model claiming strategies without leaving the platform.

When this doesn't apply

Uniformed-services retirement (military) uses separate rules from FERS. Advisors serving military retirees need a military retirement calculator in addition to — not instead of — a FERS stack.
