Contract arithmetic, not a finding that a penalty is lawful or applies. No statutory limits are inferred. A full payoff may not permit annual privileges. Excludes accrued regular interest, escrow credits, yield maintenance and defeasance. Payment savings can reflect a longer term; simple break-even is not an economic recommendation.
One assumption changes; everything else stays the same. This is a stress scenario, not a forecast.
READ THE RESULT
What the numbers are telling you.
Choose the actual charge method and its applicable window. No universal penalty is assumed.
An allowance must be confirmed usable for this specific payoff.
Break-even compares fees with payment savings, which can hide a longer repayment term.
A GOOD QUESTION
Does this determine whether a penalty is legal?
No. This is contract-based arithmetic. Ask the lender to identify the clause and provide a dated payoff statement; seek qualified advice for applicability.

Understand what the number means.
The calculation
Chargeable principal = prepayment less a confirmed applicable allowance, floored at zero. Before the entered contract window ends, apply the selected percentage or simple interest-month method. Add administration charges. Simple break-even includes new-loan costs.
