18,000 transaction costs swapping properties, saving 3,000/year (better rate or lower running costs): 6 years to break even. Below holding period, swap wins. Above, costs outweigh savings.

Property swap analysis.

Quick example

With transaction costs of 18,000 and annual saving of 3,000, the result is 6.0 years. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Transaction Costs and Annual Saving. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

Using this well

Treat the output as one point on a wider map. Run it three times — a pessimistic case, a central case, and a stretch case — and plan against the pessimistic one. That habit alone separates people who stick with an investment plan from those who bail at the first wobble.

What this doesn't capture

Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. Treat the number as one scenario, not a forecast.

Where to go next

This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the home buying costs calculator, the downsizing financial impact calculator, and the barista effect simulator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.

Frequently Asked Questions

Typical transaction costs?
5-7% of property values combined (property transfer tax, agent, legal, moving). Adds up fast.
What counts as saving?
Lower mortgage cost, smaller property running costs, area-specific savings (commute), tax advantages.
Holding period matters?
If you'll move again within break-even period, don't swap. Long-term residents win swap benefits.
Lifestyle gains not counted?
Correct — financial only. Proximity to family, better schools, or amenities have real but non-financial value.
