RefiFastCalc tells you in seconds whether a refinance is worth it.
Pick your loan type (mortgage, auto, personal, credit card or business), enter your current loan and the new offer, and get a clear verdict: your monthly savings, your total cost over the life of the loan, and the Break-Even Clock, the exact month the new loan's costs pay for themselves.
Compare side by side. Your current and new loans line up in one table, so you see every difference at a glance.
Save your loans. Keep each loan in My Loans with a live verdict, and come back when your situation or the market changes.
Know when to look again. Refi Radar checks your saved loans against current rates each time you open the app, and optional reminders nudge you at the moments that matter.
