Deferral months

Carrying cost/month

Net benefit

$150,000

Tax savings

Carrying cost

How the math works

Tax savings = gain × (current − next rate). Carrying = monthly × months. Net = savings − carry.

$5M × (37% − 32%) = $250k tax savings − $25k × 4 = $100k carry = $150k net benefit from deferral.

Frequently Asked Questions

Timing considerations?

Current vs next year rates. Tax bracket changes (personal). Lower income year (retirement, sabbatical). State tax changes. Federal legislation (election year). Each can shift tax bracket materially.

Installment sale?

Seller receives payments over 2+ years. Recognizes gain proportionally. Can spread large gain across multiple years to reduce top-bracket. Interest charged on installment. Useful for estate planning.

1031 exchange?

Complete tax deferral through like-kind exchange. 180-day completion. Must invest net proceeds in replacement property. Ideal for long-term real estate investors. Converts to step-up basis at death.

How often should I rerun this?

Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
