Refinance breakeven — current vs new mortgage

Compares the current mortgage payment against a refinance and reports the monthly saving, the months to recoup the closing costs (the breakeven), and the total-cost comparison over each loan's remaining life. Closing costs can be rolled into the new loan. Note a longer new term lowers the payment but can raise total interest. Deterministic; not lending advice.
