A garden office is a large purchase, and the question most buyers cannot answer clearly is whether it makes financial sense compared with commuting, renting a coworking desk or sharing the kitchen table. The answer depends on your own numbers: what a day of commuting costs you, how many days a month you would otherwise travel, and how much your reclaimed time is worth.

This calculator turns those inputs into a monthly savings figure and a payback period in months. It shows two versions side by side: a strict cash-only payback that counts only money you stop spending, and a full payback that also credits the hours you get back at the hourly value you choose. Neither version assumes resale value, tax deductions or salary changes.

How to use this tool

  1. Enter the all-in cost of the studio and what a single day of commuting costs you in fuel, fares, parking and tolls.
  2. Add any coworking fee you would cancel, the number of days per month the studio replaces a trip, and the minutes you would save each day.
  3. Compare the cash-only payback with the payback that credits your reclaimed hours, and check the hours you would get back every year.

What the math assumes

  • Monthly cash savings equal commute cost per day multiplied by the days entered, plus the coworking fee; nothing else is counted as a saving.
  • Time value is minutes saved per day, converted to hours, multiplied by the days entered and by the hourly value you choose; this is an opinion about your time, not a cash flow.
  • Payback in months is the total cost divided by the monthly saving, with no interest, financing cost, inflation or maintenance included.
  • Resale value, home office tax treatment, energy bills for the studio and productivity gains are all excluded; add or subtract them yourself if they matter to your decision.
  • A payback of 0 months on screen means the savings you entered are zero, so there is nothing to divide by, not that the studio is free.

Frequently asked questions

Which payback number should I trust, cash-only or including time value?

The cash-only figure is the conservative one because it counts only money you stop spending. The full figure is useful if you bill by the hour or genuinely would use the reclaimed time for paid work.

Why does my payback come out at several years?

Premium studios cost 10,000 USD or more, and a short commute does not save much cash. That does not make the studio a bad purchase; it means the case rests on comfort, focus and property value rather than pure savings.

What if I already work from home at the kitchen table?

Set the commute cost and minutes saved to 0. The cash payback will show 0 because there is no travel to avoid, and the decision becomes about workspace quality rather than money.

Can I include a possible increase in home value?

Not directly, because that depends on your market and buyer. You can subtract an estimated value gain from the total cost before entering it if you want a rough sense of the net exposure.
