This works out what you actually need for a given price and percentage, then how many months of saving it takes at your rate — including what the savings themselves earn while you wait.
It deliberately shows the deposit separately from the other cash a purchase demands. Transfer tax, legal fees and moving costs are real and cannot usually be borrowed, so they are worth planning as their own number rather than discovering at completion.
The formula
The deposit is simply price × percentage. The saving time is the compound-growth formula rearranged: months = ln(1 + (deposit × i) ÷ monthly) ÷ ln(1 + i), where i is the monthly return.
Worked example
A 300,000 property at 20% needs 60,000. Saving 1,500 a month at 4% a year, i is 0.00333, so months = ln(1 + 60,000 × 0.00333 ÷ 1,500) ÷ ln(1.00333) = 37.6, rounded up to 38 months. You contribute 57,000 of that and interest supplies the remaining 3,000.
What else you need in cash
Transfer or stamp taxes, legal and search fees, a survey, and moving costs. In most markets these add several percent of the price on top of the deposit, and lenders will not fund them.

How much deposit should I aim for?
Twenty percent is the usual benchmark because it removes mortgage insurance in most markets and gives a cushion if prices fall. Smaller deposits are widely available but increase both the loan and the total cost over the term.
Where should I keep money I am saving for a deposit?
Match the instrument to the timeline. Under three years, capital safety matters more than return — a savings account or short-duration bond fund. Longer horizons can justify some equity, moving to safety in the final year.
Does the interest really make much difference?
Over two or three years it is modest; over eight or ten it becomes significant. The calculator separates what you contributed from what the return added so you can see which is doing the work.
