Find the right calculator

Search by a decision, such as “pay mortgage earlier” or “Roth tax.”

Estimate a lower required payment and compare recasting with keeping your current payment.

Compare payment relief, cash required today, transaction fees, interest, and payoff timing under the same assumptions.

See what a one-time principal payment could save—and whether keeping your payment or estimating a recast better matches your goal.

Model recurring and one-time principal payments together, then compare the full payoff schedule.

Estimate the incremental 2026 federal tax from a fully taxable conversion and explore a simplified long-term comparison.

Compare no-fee growth with your fund and advisor costs, including the compounding that fees can no longer earn.

Deterministic formulas, official sources, and clear limitations.

Salary, balance, and tax assumptions are calculated locally and never attached to analytics.

Calculation logic and tax-year rules have separate review dates and automated tests.
