Question 1

Is renting really 'throwing money away'?

Accepted Answer

No. Rent buys shelter, flexibility, and the freedom to invest your capital elsewhere. A renter who invests the down payment and the monthly cost savings in a diversified portfolio can build comparable or greater net worth — especially over short to medium time horizons. The calculator models this directly using the opportunity cost framework.

Question 2

How is 'break-even year' calculated?

Accepted Answer

Break-even year is the first year where the buyer's net worth (home value minus remaining loan balance minus estimated selling costs) surpasses the renter's net worth (the invested portfolio). Before the break-even year, renting builds more wealth. After it, buying does.

Question 3

What investment return rate should I use?

Accepted Answer

A broadly diversified equity index fund has historically returned approximately 7–10% annually over long periods (before inflation). Conservative investors might use 5–6%; aggressive investors might use 9–10%. Use the Moderate preset (7%) as a reasonable baseline, then test the Conservative (8% — acknowledging that high stock returns favour the renter) and Aggressive (5.5% — acknowledging that high appreciation can overwhelm investment returns) scenarios.

Question 4

What appreciation rate is realistic?

Accepted Answer

US national average home appreciation has been roughly 3–4% per year historically. However, this varies enormously: some markets average 6–8% annually; others have seen flat or negative real returns for decades. Check local price data for the specific market you are considering. Use the scenario presets to bracket your estimate.

Question 5

Why does this calculator subtract selling costs from buyer net worth?

Accepted Answer

Because equity only has value when you realise it — and realising it requires a sale. Agent commissions, transfer taxes, and legal fees typically total 5–8% of the home value. A buyer who claims $200,000 in equity but would net only $160,000 after selling costs does not actually have $200,000 in realisable wealth. The calculator deducts this so comparisons are honest.

Question 6

Does the calculator include taxes on investment gains?

Accepted Answer

No — capital gains tax on the renter's portfolio is not modelled (it varies significantly by country, account type, and holding period). Similarly, mortgage interest deductibility (where applicable) is not modelled. Both omissions modestly favour the renter. Consult a tax advisor for your jurisdiction.

Question 7

How long should my time horizon be?

Accepted Answer

Use your realistic expected holding period — how long you actually plan to stay in the property before selling or moving. Short horizons (under 5 years) almost always favour renting due to the upfront dead weight of buying and selling closing costs. The break-even year shown by the calculator is the minimum holding period that makes buying financially rational under your assumptions.
