The honest answer to “should I rent or buy in Bangkok?” isn't a slogan — it's a break-even. Set the price, the rent, how long you'll stay and what your cash could earn elsewhere, and see exactly when buying pulls ahead of renting. Unbiased, no paid placement.
Compare renting an equivalent unit against buying it for cash, over a holding period you choose. Every figure below is yours to set — drag a slider or tap Type to enter an exact number. Nothing here is a market quote.
Both paths start with the same cash — the ฿5,200,000 it takes to buy (price + your transaction costs). The buyer turns it into a home that appreciates and later sells for ฿5,964,888 after selling costs; the renter keeps that cash invested at your opportunity rate. Each side's housing spend (ownership costs vs rent) is carried forward at the same opportunity rate so they compare like-for-like. Below roughly 4 years, renting tends to win because upfront and exit costs haven't been outrun yet; hold longer and buying pulls ahead. Short holds, soft appreciation and high opportunity returns favour renting; long holds and steady appreciation favour buying.

Buying carries one-off costs that renting doesn't — transfer fees and taxes at the Land Office, legal work, sometimes agent commission, and the cost of selling again at the other end. Those have to be earned back before ownership is even level with renting. If your stay is short, you simply don't hold the unit long enough to outrun them, which is why a one- or two-year horizon almost always points to renting. Flexibility is the other half of the story: a lease ends when you want it to, while selling a condo runs on the market's timeline, not yours.
Hold for many years and the maths flips. The transaction costs are now spread thin, the property has had time to appreciate, and your housing cost is no longer a rent cheque that climbs every year. The calculator captures this by comparing two parallel worlds with the same starting cash: in one you buy the home, in the other you keep that cash invested and pay rent from it. Whichever ends with more wealth wins — and the year the two cross is your break-even.
It won't pretend to know Bangkok's future. It asserts no market appreciation, no “typical” rent and no guaranteed return — those are all yours to set, because honest assumptions beat confident-sounding defaults. It models a cash purchase, since that's the usual route for foreign condo buyers under Thailand's foreign-currency remittance rule, and it isn't tax advice. Treat the output as a clear, transparent comparison of your assumptions — then pressure-test it by changing them.
Model the true buy-side cost next, then sanity-check the yield if you'd rent it out.
