What are your estimated closing costs?
All-in: origination, appraisal, title, recording, etc. If you have a Loan Estimate, use that number. No quote yet? $5,500 is a fair national average on a $285k refi.
Current vs new monthly payment
Use principal and interest only -- not escrow. Find your current P+I on your statement. Your lender's Loan Estimate lists the new one.
How long do you plan to keep this loan?
Pick your most likely hold. If you're unsure, go shorter -- it's the more conservative assumption.

How the break-even math works
Break-even = costs divided by savings
The formula is simple: take your total closing costs and divide by monthly savings (old payment minus new payment). The result is how many months until the refi fully pays for itself.
Hold horizon is everything
A refi with a 36-month break-even is great if you plan to stay 10 years. It is a loss if you sell in 2 years. The break-even number is only useful in context of how long you keep the loan.
Net gain accounts for the cost
Cumulative savings at your horizon minus closing costs gives you the true net. A refi can look good monthly but still net negative if the term is short or costs are high.
