What does this calculator estimate?
The price-to-rent ratio compares a property's price to its annual rent, telling you whether buying beats renting in a given market. A lower ratio favors buying; a higher ratio favors continuing to rent. Enter the price and monthly rent to get yours.
- Price-to-rent = price ÷ (monthly rent × 12)
- Under ~15 tends to favor buying, over ~20 favors renting
- A market-level buy-vs-rent gauge
What the price-to-rent ratio says
The ratio compares the cost of buying to the cost of renting the same home. Lower ratios favor buying; higher ratios favor renting. Common guidance: under 15–20 buying is usually ahead; above that, renting and investing the difference often wins.
Limitations to watch for
The ratio is a market screen, not a personal decision — your horizon, rates, and mobility matter more. It ignores taxes, maintenance, appreciation, and investment returns on saved money. Compare the same home type in the same area.
How to use it in practice
Divide prices by annual rents for the area you're considering. Use it to sense-check the rent-vs-buy decision, then run the full rent-vs-buy calculator with your actual numbers.

What the price-to-rent ratio measures
Price-to-rent is the home price divided by annual rent for the same property: a $300,000 home renting for $2,000 monthly has a ratio of 12.5 (300,000 ÷ 24,000). It compares the cost of buying to the cost of renting the same home.
The buying-vs-renting decision
A ratio under 15 generally favors buying; above 20 favors renting; 15–20 is a judgment zone. The ratio is a screen, not a verdict — local appreciation, interest rates, and how long you will stay shift the real comparison.
How the ratio works
The ratio is roughly the number of years of rent equal to the purchase price. A ratio of 20 means 20 years of rent equals the price — buying only wins if you stay long enough for ownership costs and appreciation to beat renting.
A worked example
A home priced at $280,000 renting for $1,800 monthly: ratio = 280,000 ÷ 21,600 ≈ 13.0 — favors buying. The same home at $350,000: ratio ≈ 16.2 — the judgment zone. The calculator returns the ratio and its rough interpretation.
Limits of the ratio
The ratio ignores down payments, mortgage rates, taxes, maintenance, and rent growth — the inputs that decide the real comparison. Use it to screen markets, then run a full buy-vs-rent model with your numbers.
How this calculator works
Formula
Price-to-rent ratio = property price ÷ annual rent. It indicates whether buying or renting is financially favored in a market.
Worked example
$300,000 price with $24,000 annual rent: ratio = 12.5.
Assumptions to verify
- Price and rent are for comparable homes.
- Annual rent = monthly × 12.
- The ratio is a market-level signal.
Frequently asked questions
What is the price-to-rent ratio?
Home price ÷ annual rent: $300,000 ÷ $24,000 = 12.5.
What does a high ratio mean?
Renting is relatively attractive — prices are high compared to rents.
What's a good threshold?
Under 15–20 generally favors buying; above that, renting often wins after investing the difference.
Is it a personal decision?
No — it's a market screen. Your timeline, rates, and mobility matter more for the actual choice.
How is it different from GRM?
GRM is the investor's lens (same math); price-to-rent is the homeowner's buy-vs-rent signal.
What does 12.5 mean practically?
12.5 years of rent equals the purchase price — a moderately buy-friendly market.
How do I find the data?
Use median home prices and median rents in the city or neighborhood you're considering.
What is a good price-to-rent ratio?
Under 15 favors buying; above 20 favors renting; 15–20 is a judgment zone.
How do I calculate it?
Home price ÷ annual rent for the same property.
Is the ratio the full answer?
No — it screens; interest rates, taxes, maintenance, and time in home decide.
What does a ratio of 20 mean?
Twenty years of rent equals the price — buying pays off only over a long stay.
