The deposit is the wall almost every buyer hits first. Treat it like a disciplined investor treats any funding target: a fixed monthly transfer, automated, non-negotiable — not whatever happens to be left over at month-end.
A rough monthly target and timeline — for the exact country-adjusted version with currency switching, use the full Down Payment Planner.
A widely used baseline: 50% of net income to needs (rent, food, utilities, minimum debt payments), 30% to wants, 20% to savings and extra debt repayment. If you're actively saving for a deposit, most people need to push savings well past 20% for a few years — the estimator above shows what 10%, 20% and 30% actually mean in months, not just percentages.
Some buyers consider a short-term personal loan or bridging loan to top up a deposit that's close but not quite there. It is possible in some markets — but weigh it carefully:
Your deposit isn't the only cash you need on completion day. Two more calculators most buyers underestimate:
Notary, agent commission and transfer taxes — 2% to 15% on top of the price depending on country.
Property tax and maintenance you'll pay every year after you move in — budget for it before you buy, not after.
Country-adjusted, currency-switching, with a real month-by-month countdown.
