How the Mortgage Refinance Calculator template works

Break-even months for refinancing given new rate and closing costs. Open the spreadsheet, enter your own numbers, and let the formulas do the math.

When this template helps

01

You are deciding between two financial options and need a quick number.

02

You want to see how changing one input (rate, years, amount) shifts the result.

03

You want a calculation you can save and revisit, not a one-shot web form.

04

You want to tweak the math - this is a spreadsheet, not a black box.

Tips to get the most out of it

  • Keep the column labels simple - the formulas work best when categories are consistent month to month.
  • Compare to staying put regularly - once a week is a good rhythm for most people.

Common mistakes to avoid

  • Treating the result as a decision rather than an input. Calculators answer "what if" - the final call is yours.
  • Mixing up annual and monthly rates. If a formula uses a monthly rate, divide the annual by 12 before entering.
  • Ignoring taxes, fees, or assumptions. A result is only as good as the inputs you feed it.

Frequently Asked Questions

What is the difference between Free, Essentials, and Ultimate?

Free is a single-sheet starter template (sample data + How to Use guide). Essentials ($12) adds a dashboard, charts, expanded categories, and pre-filled subcategories. Ultimate (when available) adds multi-entity tracking, scenario analysis, and power-user reporting across 6-7 interconnected sheets.

Should I upgrade to Essentials?

Upgrade to Essentials if you want a dashboard with charts, more categories, larger capacity, and a more polished spreadsheet for ongoing use. The Free version is a good fit for one-off planning or trying out the layout.

Is Essentials worth $12?

Essentials is a one-time $12 purchase with no subscription. It typically adds a full dashboard, 30-50% more categories or rows than the Free version, and richer formulas. Most buyers upgrade after using the Free version for a few weeks and hitting its limits.

What is included in the free version?

The Essentials version ($12) adds a dashboard, larger capacity, and extended categories; Ultimate (when available) adds multi-entity tracking and ultimate-grade reporting.

Which inputs should I edit?

Only the cells marked as inputs at the top. The rest are formula-driven outputs that update automatically when inputs change.

Save multiple copies of the file for different scenarios, or upgrade to Essentials/Ultimate for side-by-side scenario comparison in one workbook.
