The problem

Monte Carlo is opaque, random, and unexplainable.

The tools most people rely on today create more confusion than confidence.

Black-box outputs

People don't trust black-box outputs.

Randomness

Engineers hate randomness.

Hard to explain

Probability-based results are hard to explain — and harder to act on.

The solution

RetireLogica is the deterministic truth model that shows the math behind the plan.

Transparent projections

Year-by-year projections with every number traceable — full tax breakdown, withdrawal ordering, and verification checks.

Full control

Full control over every assumption — growth rate, filing status, conversion amounts, ACA caps, cost basis, and more.

Built-in optimizers

Roth conversion and Social Security optimizers analyze strategies against the full tax model — IRMAA, NIIT, and capital gains included.

New in RetireLogica

Budget Planner, Security Controls & Publishing Tools

Build spending plans with line-item budgets and Schedule E rental cash flow, review year-by-year projection tables, protect your account with MFA and recovery codes, and read planning articles with verification-backed publishing.

Engine & Optimizer Tools

Deterministic Withdrawal Engine

Math-based withdrawals with no randomness — every number has a source.

4-Phase Retirement Model

Accumulation, ACA Shield, Roth Conversion, and Longevity — each phase with distinct tax-aware rules.

Full Federal Tax Model

Brackets, LTCG stacking, NIIT surtax, Social Security torpedo, IRMAA surcharges, and RMDs — all built in.

Account-Type Aware Withdrawals

Traditional IRA and 401(k)/employer-plan balances are modeled as distinct accounts from the first input, and each can be selected as its own withdrawal source in the spending plan — the engine applies the 10% penalty before age 59½ to IRA distributions and honors the Rule of 55 for employer plans.

Roth Conversion Optimizer

Compare your conversion strategy against bracket-optimized alternatives with full tax, IRMAA, and widow's penalty modeling.

Stress Testing & Execution Risk

Test plans against real market sequences — 1966 Stagflation, 2000 Lost Decade, 2008 Crisis — 1,000-scenario resilience grading, and discrete life-event shocks.

Social Security Optimizer

Compare claiming at 62, 65, 67, and 70 with spousal coordination, survivor benefits, and earnings test analysis.

ACA MAGI & Projection Tables

Use the ACA decade engine, tax assumptions guide, and detailed projection table to inspect MAGI, taxes, IRMAA, RMDs, and balances year by year.

Security & Recovery

MFA, recovery codes, password recovery, and purchase restoration keep paid access and planning content manageable across devices.

Why we built RetireLogica

We built RetireLogica because Monte Carlo tools confuse people and hide the logic. Everyone deserves a planning engine that shows the math — not a black box that outputs probabilities. You should be able to inspect the assumptions, follow the calculations, and understand your plan without handing the explanation to someone else.
