The honest comparison, including the costs nobody mentions
The honest comparison, including the costs nobody mentions
The common version compares rent against a mortgage payment and concludes that buying wins whenever the payment is similar. That comparison is not close to complete, because a mortgage payment is only part of what owning costs.
Owning also means property tax, homeowners insurance, maintenance, and eventually major repairs. Together these commonly add 40–50% on top of principal and interest. Meanwhile, part of each mortgage payment builds equity, which renting does not. This calculator accounts for both sides.
Beyond principal and interest:
On the $400,000 example, a $2,022 mortgage payment becomes roughly $2,880 all in. That is the number to compare against rent — not the mortgage alone.
Buying costs 2–5% of the price in closing costs. Selling costs 6–10% once agent commission, transfer taxes, and preparation are included. Together that is commonly 8–15% of the home's value, paid within a single ownership cycle.
This is why time horizon dominates the answer. Over a short stay, those costs swamp any equity built or appreciation earned. The often-quoted five-year rule exists because that is roughly how long it takes for ownership benefits to outweigh transaction costs at typical rates and appreciation — though the real crossover varies from three years in cheap, fast-appreciating markets to a decade or more in expensive, flat ones.
Renting is often framed as throwing money away. It is more accurate to say you are buying something different: flexibility, a capped and predictable cost, and freedom from maintenance risk. When a boiler fails, a renter makes a phone call and an owner writes a cheque.
There is also an opportunity-cost argument that is frequently ignored. A $80,000 deposit invested rather than spent has an expected return of its own. If renting is meaningfully cheaper monthly and the difference is genuinely invested, renting can come out ahead financially over long periods. The critical condition is that the difference is actually invested rather than absorbed into spending — which is where the argument usually fails in practice.
The calculator compares total cash spent renting against total cash spent owning over your stated horizon, then credits ownership with the equity you have built. A positive figure favours buying; a negative one favours renting.
Treat the output as a directional guide rather than a verdict. It cannot predict appreciation, which is the single largest variable and the least knowable. It also cannot price the non-financial factors that often matter more: stability for children in school, the freedom to take a job in another city, or the value of being able to change your own kitchen. Run the numbers, then weigh them against those.
No. Buying tends to win over long horizons in markets with moderate prices relative to rents. Renting can win over short stays, in expensive markets, or when the monthly difference is genuinely invested. Time horizon is usually the deciding factor.
Around five years is the common rule of thumb, because that is roughly how long it takes for equity and appreciation to exceed the 8-15% of value lost to buying and selling costs. The real figure ranges from three years to over ten depending on the market.
Property tax, homeowners insurance, maintenance at roughly 1% of value per year, HOA fees where they apply, and major repairs that arrive without warning. Together these commonly add 40-50% on top of the mortgage payment.
No more than any purchased service. Rent buys housing, flexibility, a predictable cost, and freedom from maintenance risk. The relevant comparison is total cost of each option over your horizon, not whether one builds equity.
