Home & Mortgage
Rent vs Buy Calculator
Compare the long-term financial tradeoff between renting and buying based on your timeline, mortgage terms, and home appreciation assumptions.
Projection outlook
Track the projected balance against the target line so you can see whether the current plan fully closes the gap.
The projection reaches the target with roughly $280,283 of modeled cushion by year 7.
Buy vs rent wealth path
Compare home value growth and invested renter value over your expected time horizon.
Principal vs interest breakdown
Review how much of the payoff goes toward reducing balance versus servicing interest.
Owner equity is the largest component at about 61.0% of the total modeled amount.
Scenario comparison
Use the spread between scenarios to see how sensitive this outcome is to the assumptions you change first.
Optimistic currently leads conservative by about $55,000, which shows the approximate range across the modeled cases.

How to use this output
Start with the main result at the top. Then review the key numbers, look at how the chart changes over time, and compare the Base, Optimistic, and Conservative scenarios before making a decision.
Saved scenarios
Save multiple scenarios to compare optimistic, conservative, and custom planning paths later.
What this tool does
- Compares approximate owner equity with an invested renter alternative over the same time horizon.
- Helps you think in terms of net position rather than just monthly payment.
- Frames the decision as a time-horizon tradeoff rather than a purely emotional choice.
Example scenario
If you may move again in five to seven years, the outcome can look very different from a twenty-year ownership plan even with the same home price and mortgage rate.
Key assumptions
- This model simplifies taxes, maintenance, insurance, and transaction costs to keep the comparison directional.
- Buying assumes a fixed-rate mortgage and home appreciation at the modeled rate.
- Renting assumes the down payment difference can be invested at the chosen return.

How the math works
Open to review the formulas and planning logic behind this tool.
- 1.The buy side estimates mortgage amortization and home appreciation over the chosen years in home.
- 2.The rent side assumes the down payment stays invested and compounds at the chosen investment return.
Common mistakes
- Comparing rent to a full housing payment without considering ownership equity.
- Ignoring mobility and transaction costs.
- Assuming home appreciation will always outpace alternative investments.

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.
