When renting usually wins
Renting often compares well for short stays, uncertain plans, high mortgage rates, or when rent is low relative to purchase prices.

Rent vs Buy Calculator: Should I Rent or Buy a Home?
Estimate whether buying or renting is cheaper over the length of time you expect to stay. The comparison includes mortgage payments, rent growth, home equity, investment opportunity cost, ownership expenses, and inflation.
What you’ll get: a plain-English recommendation, estimated break-even year, monthly and total cost difference, opportunity-cost breakdown, chart, and a year-by-year comparison. Example: a short stay often favours renting because buying and selling costs have less time to be recovered.

How this rent vs buy comparison works
The calculator runs a month-by-month mortgage and renting comparison for up to 30 years. Buying includes the down payment, purchase costs, mortgage principal and interest, PMI, property tax, insurance, maintenance, HOA charges, appreciation, and selling costs. Renting includes the deposit, fees, insurance, utilities difference, and annual rent growth.
Opportunity cost is always visible: money committed to the down payment and buying costs, plus any monthly amount by which owning costs more, is assumed to earn the alternative investment return. The refundable rental deposit remains an asset. Future net costs are discounted by general inflation so amounts at different horizons are easier to compare.
How to use it:
- Enter your home price, down payment, loan rate, and loan term.
- Add your ongoing owner costs such as property tax, insurance, maintenance, and HOA.
- Fill in rent and expected annual rent increases.
- Set your time horizon, investment return, and advanced inflation assumptions.
- Click Compare to see the recommendation, breakdown, chart, and yearly table.
This comparison is useful for estimating a break-even point, understanding opportunity cost, and exploring “what if” scenarios like higher interest rates or faster home appreciation. For example, you can test whether a lower monthly rent invested at a modest return could compete with home equity growth, or how rising maintenance costs affect the ownership path. It is also a practical way to evaluate a potential relocation, a larger down payment, or changes in the housing market.
Assumptions & limits
- Income taxes, mortgage-interest deductions, capital-gains tax, moving costs, and financing fees are not automatically modeled.
- Use the manual purchase-cost field for stamp duty, land transfer tax, legal fees, or inspections.
- Investment returns, home appreciation, and inflation are smooth assumptions; real markets vary.
- Lower inflation-adjusted net cost is better, but affordability, risk, and flexibility still matter.
Practical rent-or-buy decision factors
When buying usually wins
Buying becomes more competitive with a long stay, manageable transaction costs, affordable financing, and sustained equity growth.
Long horizon
Hidden ownership costs
Property tax, insurance, PMI, maintenance, service charges, repairs, and selling fees do not build equity and can rival mortgage interest.
Beyond P&I
How long you plan to stay
Buying costs are front-loaded. A longer stay spreads them over more years, while selling costs make an early move particularly important to model.
Break-even
What this calculator excludes
It cannot price lifestyle preferences, job mobility, renovation surprises, market volatility, personal tax rules, or the value of housing stability.
Personal factors
Methodology and formulas
Monthly mortgage payment
M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]
P is loan principal, r is monthly APR, and n is the number of payments.
Balance and equity
Balanceₘ = Balanceₘ₋₁(1+r) − payment; Equityₘ = home valueₘ − Balanceₘ
Rent and investment growth
Rentᵧ = starting rent × (1 + rent growth)ʸ; Investmentₘ = Investmentₘ₋₁(1 + annual return/12) + ownership premiumₘ
Net cost and break-even
Buy cost = owner cash + opportunity cost − net sale proceeds; Rent cost = renter cash − refundable deposit. Real cost = nominal cost ÷ (1 + inflation)^(months/12). Break-even is the first month buy cost ≤ rent cost after renting was cheaper.

Rent vs buy questions
How long do I need to stay for buying to make sense?
There is no universal answer. Buying needs enough time for equity and avoided rent to overcome purchase, financing, upkeep, and selling costs. Use the first break-even month reported above.
Is rent wasted money?
No. Rent buys housing, flexibility, and freedom from many repair and property-price risks. Owners also pay unrecoverable interest, tax, insurance, upkeep, and fees.
How should I estimate maintenance?
A rough starting range is 1%–2% of home value annually, adjusted for age and condition. A property-specific inspection and repair plan is better.
How do property taxes affect the result?
They add recurring cost without creating equity. The calculator grows property taxes separately each year, so a higher rate usually delays break-even.
Are taxes and deductions included?
Property tax and a manual purchase-tax field are included. Personal income tax, capital gains, mortgage deductions, and reliefs are excluded.
How does down-payment opportunity cost work?
The calculator compounds the down payment and buying costs at your alternative return, then adds positive monthly ownership premiums.
What is PMI?
Private mortgage insurance protects the lender on many low-down-payment loans. Enter its monthly amount and the loan-to-value threshold at which it ends.
Why do selling costs matter?
Agent, legal, and transfer costs reduce sale proceeds and can erase several years of apparent buying advantage.
How does inflation change the comparison?
Expense-specific rates grow future costs, while general inflation discounts both paths into present-value terms.
