Model overview
Understand the model at a glance
What this model does
- Compares current and refinance monthly payments side by side.
- Estimates the breakeven point on refinance costs.
- Shows whether the refinance improves cash flow, lifetime interest, or both.
Key assumptions
- The refinance costs are treated as upfront cash outflows.
- Both current and new loans are modeled as fixed-rate principal-and-interest loans.
- The analysis does not include tax effects or cash-out refinancing.
Example scenario
A lower rate can reduce monthly payment, but if the term resets too long or the costs are high, the refinance may not be as compelling as it first appears.

How the math works
Open to review the formulas and planning logic behind this model.
- The calculator computes a standard monthly payment for the current loan and the proposed refinance loan.
- It estimates breakeven by dividing the upfront costs by monthly payment savings where that comparison is meaningful.

Questions
FAQ
Are these outputs guarantees?
No. They are planning estimates based on your assumptions and should be updated as markets, taxes, and spending change.
Do these calculators replace professional advice?
No. They are a strong planning starting point, but tax, legal, and investment decisions should be reviewed with a qualified professional when appropriate.
How often should I revisit my inputs?
A good rule is to revisit assumptions after major income, spending, family, tax, or market changes and at least a few times per year.
Why do the optimistic and conservative scenarios matter?
They help you see how sensitive the result is to assumptions instead of anchoring on one exact output.
Should I include inflation separately?
Yes when the calculator allows it. Separating inflation from returns usually makes the planning logic easier to understand.
What if my real life differs from the model?
That is normal. Use the output as a planning range and update the scenario as new information arrives.
Which metric should I pay attention to first?
Start with the headline summary and the first two or three result cards. Those usually hold the most decision-useful information.
Can I share these results with someone else?
Yes. Major calculators support shareable URL state so you can copy the scenario link and send it directly.
