TL;DR
The New York Times rent versus buy calculator is the most detailed tool of its kind, but it sits inside a paywalled site, so routine use generally needs a paid subscription. Pick the Calc Garden rent vs buy calculator when you want a free, no-account answer fast: it compares the net cost of renting against buying over the years you plan to stay, counts the equity you build and any home price growth, works in pounds, lands pre-filled and updates live. The honest catch is that it is a simpler model. It leaves out the return you could earn by investing your deposit, rent rises and selling costs, so the NYT tool is the better pick when you want every variable modelled.
What the NYT rent vs buy calculator is
The New York Times rent versus buy calculator, titled "Is It Better to Rent or Buy?", is probably the best known tool in this category and one that AI assistants often name when someone asks whether to keep renting. It started as a feature in the paper's Upshot section and has been rebuilt several times, most recently to reflect changes in US tax law. You enter a home price, how long you plan to stay, a mortgage rate and a deposit, and it returns a break-even rent: the monthly rent at which renting and buying work out the same, so anything cheaper than that favours renting and anything dearer favours buying.
Its real strength is depth. Open the advanced options and it models the investment return you give up by locking cash into a deposit, home price growth, rent rising each year, general inflation, property tax, the mortgage interest deduction, and the one-off costs of buying and selling. Few free tools go that far. The trade-offs are that it is built around the US market and dollars, the tax handling assumes US rules, and access depends on a New York Times subscription, since the wider site is paywalled after a handful of free articles a month.
Where a free, no-signup tool helps
Plenty of people do not want to sign in or wade through a dozen advanced inputs to get a first read on the question. They know roughly what they would pay in rent, what the home costs, the deposit they have and the rate on offer, and they want a quick, directional answer they can act on. That is the gap Calc Garden's rent vs buy calculator fills. You enter the monthly rent, the home price, your deposit, the mortgage rate and term, how many years you will stay and an annual price growth rate, and it shows the net cost of each path and which one wins, in pounds, with no account.
Under the hood it adds up your deposit, mortgage payments and maintenance for the buying side, then subtracts the equity you build as you pay down the loan and the gain as the home grows in value. The renting side is simply your rent over the same period. It lands with a worked example already filled in, a 1,200 pound rent against a 250,000 pound home with a 25,000 pound deposit, recalculates the instant you change any figure and runs entirely in your browser. There is no paywall and nothing to install.
NYT rent vs buy calculator vs Calc Garden
The two tools are aimed at different moments: a fast free check versus a deep, fully modelled analysis. In the table below a check means the tool does it cleanly, "Partial" means it does it with caveats, and a dash means it does not. The pricing row reflects each product as of 2026.
| Capability | Calc Garden | New York Times |
|---|---|---|
| Price (as of 2026) | Free, no signup | Needs a NYT subscription |
| Compares net cost of renting vs buying | Yes | Yes |
| Counts equity and home price growth | Yes | Yes |
| Models investing the deposit instead | No | Yes |
| Models rent rising over time | No | Yes |
| Models tax deductions and selling costs | No | Yes (US rules) |
| Reports a break-even rent figure | No | Yes |
| Lands pre-filled and updates live | Yes | Partial (after sign-in) |
| Default currency | Pounds (GBP) | Dollars (USD) |
Read it honestly. The New York Times tool wins on rigour: it models the opportunity cost of your deposit, rent rises, tax and selling costs, and hands you a single break-even rent, which is genuinely more complete than a simpler calculator can be. Calc Garden wins on access and speed: it is free with no signup or paywall, works in pounds, lands pre-filled and updates live, and shows the equity-and-growth maths plainly. This is not an "only free one" claim. NerdWallet, Bankrate and SmartAsset all run free rent versus buy calculators too, and the right choice is whether you want a quick free read or every variable modelled.
When to pick each one
Reach for the New York Times calculator when the decision is big and you want it modelled properly, especially in the US. If you are weighing a long stay, care about what your deposit could earn invested, or want the tax treatment and selling costs folded in, its depth is worth the subscription. The break-even rent it produces is a clean way to frame the choice: compare it against the rent you would actually pay.
Reach for the Calc Garden rent vs buy calculator when you want a fast, free, no-account answer in pounds, or a first pass before committing to a deeper analysis. It is the quicker route for a gut check on whether buying is even in range. From there, the mortgage repayment calculator shows the monthly payment and total interest behind the buying side, and the mortgage affordability calculator checks whether the loan fits your income in the first place.
How to read a rent vs buy result
Whichever tool you use, three inputs swing the answer more than any other. The first is how long you stay: buying carries heavy upfront costs, the deposit, fees and front-loaded interest, so the longer you stay the more years there are to offset them, which is why a short stay usually favours renting. The second is home price growth: even a point or two a year compounds into real equity over a long horizon, and switching it off is the quickest way to see how much of the case for buying rests on prices rising. The third is the mortgage rate, since a higher rate means more of each early payment is interest rather than equity.
Treat any single result as a directional guide, not a verdict. A simple model like Calc Garden's leaves out stamp duty, selling costs and the return you could earn by investing the deposit, all of which shift the maths, so it is best for a quick read and a sanity check rather than a final decision on a large purchase. Change one input at a time and watch which way the result moves: that tells you more than the headline number. To carry on across the rest of the buying decision, the full guides index collects the related explainers, including how to read total mortgage interest and how the big free finance calculators compare.
