Rent vs Buy Calculator: Price-to-Rent Ratio & 10-Year Wealth Modeling
The choice between renting and purchasing residential real estate is frequently clouded by emotional platitudes rather than objective financial arithmetic. Evaluating total unrecoverable housing expenses, investment opportunity costs, and frictional transaction fees across your expected geographical tenure reveals whether buying or renting maximizes long-term net worth.
The 5% Rule of Unrecoverable Homeownership Costs
When comparing housing options, both renting and buying incur ‘unrecoverable’ costs—money spent that never builds equity:
- Unrecoverable Renting Cost: Your monthly rent check and modest renter’s insurance premium ($15/mo).
- Unrecoverable Buying Costs (The 5% Rule):
- Property Taxes (~1.0% to 1.5%): Mandatory municipal assessments that build zero personal equity.
- Maintenance & CapEx (~1.0%): Routine repairs, appliance replacements, roof patches, and HVAC upkeep.
- Cost of Capital (~3.0% to 4.5%): The interest paid to the mortgage lender plus the lost investment return (opportunity cost) of having down payment cash locked into home equity rather than compounding in equity markets.
10-Year Comprehensive Financial Comparison ($450,000 Home vs $2,400/mo Rent)
The table below models a 10-year horizon assuming a $450,000 home purchase (20% down, 6.75% mortgage) versus renting a comparable home starting at $2,400/month (3% rent inflation), with down payment savings invested at 8% CAGR.
| 10-Year Financial Category | Buying the $450,000 Home | Renting ($2,400/mo) & Investing | Financial Variance |
|---|---|---|---|
| Initial Cash Outlay | $90,000 (Down) + $12,000 (Closing) | $2,400 (Deposit) | Renter retains $99,600 liquid cash. |
| Cumulative Housing Payments (10 Yrs) | $279,720 (P&I payments) | $330,160 (Rent across 10 years) | Owner monthly cash out-of-pocket is lower. |
| Property Taxes & Insurance (10 Yrs) | $72,000 | $1,800 (Renter insurance) | Owner pays $70,200 more in tax/escrow. |
| Home Maintenance & Repairs (10 Yrs) | $45,000 (1% rule) | $0 (Landlord obligation) | Owner absorbs $45,000 in repair outlays. |
| Future Home Market Value (10 Yrs @ 3%) | $604,760 | — | Home appreciates by $154,760. |
| Remaining Mortgage Balance | −$292,300 | $0 | Owner built $67,700 in principal paydown. |
| Round-Trip Disposition Costs (Selling 7%) | −$42,333 | $0 | Owner pays sales commissions. |
| Renter Investment Portfolio Value | $0 | $248,500 | Down payment + savings grown @ 8% CAGR. |
| Net Net Worth Accumulated (10 Years) | $270,127 (Home Equity) | $248,500 (Liquid Stock Portfolio) | Owner ahead by $21,627 after 10 years. |

Strategic Guidelines: When to Rent vs When to Buy
- Buy If: You are confident you will remain in the exact same metropolitan area for at least 6 to 7 years, have a stable career, value remodeling freedom, and want forced monthly equity savings.
- Rent If: Your tenure horizon is under 5 years, your local Price-to-Rent ratio is above 20, you value geographic career mobility, or you prefer investing capital into diversified, liquid global equity markets without debt leverage.
How to Use This Calculator
Formula:
Price-to-Rent Ratio = Median Home Purchase Price ÷ Annual Gross Rent | 5% Rule: Annual Cost of Homeownership = 1% Property Tax + 1% Maintenance + 3% Cost of Capital | Net Wealth Comparison over 10 Years
- Input the purchase price of the home you are considering, along with the planned down payment percentage and mortgage interest rate.
- Specify ongoing ownership costs: annual property tax percentage, hazard insurance, HOA dues, and annual maintenance budget (typically 1% of home value).
- Enter the monthly rent for an equivalent comparable rental home, expected annual rent inflation (typically 3% to 4%), and monthly renters insurance.
- Set financial assumptions: investment return on down payment savings (e.g., 7% to 8% in index funds) and annual home appreciation rate (typically 3% to 4%).
- Inspect the crossover break-even year, total cumulative unrecoverable costs of buying versus renting, and net net worth projections over 5, 10, and 20-year horizons.
Frequently Asked Questions
The Price-to-Rent ratio is calculated by dividing the purchase price of a home by the total annual rent of a comparable property (Home Price ÷ Annual Rent). A ratio of 1 to 15 indicates that buying is significantly more favorable than renting; a ratio of 16 to 20 suggests renting and buying are roughly balanced; and a ratio of 21 or higher strongly favors renting, as home purchase prices are disconnected from rental yields.
Popularized by portfolio manager Ben Felix, the 5% Rule estimates the annual unrecoverable cost of homeownership as approximately 5% of the home's total value: 1% for municipal property taxes, 1% for routine maintenance and structural repairs, and 3% for the cost of capital (mortgage interest or the opportunity cost of equity). If monthly rent on an equivalent home is lower than 5% of the purchase price divided by 12, renting is mathematically cheaper.
No. Rent is the maximum amount you will pay for housing in any given month, whereas a mortgage payment is the absolute minimum you will pay. Homeownership incurs massive unrecoverable expenses that do not build equity: mortgage interest (which consumes ~70% of early payments), property taxes, homeowners insurance, private mortgage insurance (PMI), HOA fees, maintenance, and 8% to 10% round-trip transaction commissions upon buying and selling.
Because buying and selling residential real estate involves substantial frictional transaction costs (2% to 4% buyer closing costs and 6% to 8% seller commissions and transfer fees), the typical break-even timeline is approximately 4 to 6 years. If you move within 3 years of purchasing, high transaction fees and front-loaded mortgage interest almost always make buying more expensive than renting.
A renter does not tie up $80,000 to $100,000 in home equity or pay thousands in annual closing and maintenance fees. If the renter disciplinedly invests that initial down payment capital and any monthly cash savings into a low-cost, diversified equity index fund compounding at 8% to 10% per year, the resulting liquid stock portfolio frequently matches or surpasses the net home equity of a homeowner over 10 to 15 years.
Non-financial factors often drive the decision: buying offers complete control over remodeling, pet ownership, stability against landlord non-renewals, and pride of ownership. Renting provides unparalleled career flexibility to relocate, zero personal responsibility for expensive structural repairs, and immunity from local housing market downturns.
