Charitable Lead Annuity Trust (CLAT) Optimizer
A Grantor CLAT pays a fixed annuity to charity for a set term, then passes remaining assets to heirs — potentially tax-free. This tool finds the inflection point where a CLAT outperforms keeping assets in a taxable brokerage account.

Backwards Design: $210k AGI Target
Uses a zeroed-out CLAT (120% escalating payout), a 0.5% AGI floor, and the annual AGI deduction cap based on asset type.

Strategic Architect README: Ask, Execution, Logic
The Ask: Determine the Optimization Inflection Point where a Grantor CLAT becomes more efficient than a standard brokerage path, while exposing the annual grantor tax drag and validating resilience under a Year 1 market crash.
The Execution: A single-page, state-driven simulation recomputes 20-year paths whenever any input changes. The model hardcodes OBBBA 2026 rules (0.5% AGI floor and 35% benefit cap) and treats the refund as a 25% down payment that powers the Path 3 real-estate node.
The Logic Layers:
- Input and Tax Recapture: Convert AGI into a post-tax Status Quo principal and compute the CLAT principal advantage plus OBBBA refund.
- Simulation Loop: Project Status Quo growth (after annual tax drag) versus CLAT growth (pre-tax, with grantor-paid taxes and fixed annuity payout).
- Path Comparison: Compare Status Quo, CLAT Core, and CLAT Multiplier with inflation-adjusted real values for year 20.
Strategic Formula Bank
2. Principal Advantage: principalAdv = Principal - sqStart
3. OBBBA Refund: refund = max(0, min(AGI * deductionLimit, Principal * 0.75) - (AGI * 0.5%)) * 0.35
4. Annual Payout (Annuity): annuity = P * [r / (1 - (1+r)^-n)] where r = 4.6% and n = 20
5. Grantor Tax Drag (annual): taxDrag = max(0, CLAT * appliedGrowth) * combinedTaxRate
6. RE Multiplier Value: reValue = (refund / 0.25) * (1 + reGrowth)^t
7. Wealth Advantage: advantage = (CLAT + RE) - StatusQuo
8. Inflation Deflator: realValue = nominal / (1 + inflationRate)^20

AGI Flip Analysis (Baseline)
Baseline-only sweep. Charity utility credit adds a % of total charity payout to the GO test. Example: a 50% credit treats $1 of charity as $0.50 of personal benefit in the flip decision. A “GO” requires both Core and Multiplier (plus charity credit) to beat Status Quo, and annual grantor tax drag ≤ 10% of AGI.

How to Read the Flip Summary (Plain English)
- Core+Charity beats Status Quo: the first AGI where the CLAT Core (plus charity credit) ends higher than the Status Quo path.
- Multiplier+Charity beats Status Quo: the first AGI where the CLAT Multiplier (plus charity credit) ends higher than the Status Quo path.
- GO (both + tax drag ≤ 10% AGI): the first AGI where both comparisons are positive and the annual grantor tax drag stays below 10% of AGI.
- Principal rule: only the AGI above the bracket cutoff is used to fund the CLAT in the sweep.
- Range and steps: the income values tested (from the start AGI to the end AGI, in $50k jumps).
- Payout rate: the annual CLAT payout as a % of the swept principal (based on your current inputs).
- Charity credit: how much personal benefit you assign to each $1 of charity (50% means $0.50 of benefit).
Plain-English Summary (Read Me)
- This tool compares a CLAT strategy against a standard taxable brokerage (Status Quo).
- In the AGI sweep, your income is tested from about $403k to $1.5M in $50k steps.
- The CLAT principal in the sweep is only the income above a chosen tax bracket cutoff.
- The CLAT Core path shows trust growth after payouts, without the real estate multiplier.
- The CLAT Multiplier path adds a real estate node funded by the tax refund.
- The flip decision checks if CLAT Core and CLAT Multiplier both beat Status Quo.
- Charity utility credit lets you value the charitable giving in the decision math.
- A 50% credit means every $1 to charity counts as $0.50 of personal benefit.
- A "GO" only shows if tax drag is 10% of AGI or less.
- Real values show inflation-adjusted purchasing power for year 20.
