Set your target, enter what you can save each month, and see exactly when you'll hit your deposit goal. Then use the budget tool to find extra savings.
The benchmark is 20% of the purchase price. Hitting 20% usually unlocks better mortgage rates and avoids mortgage insurance (PMI in the US, LMI in Australia). Some schemes let first-time buyers in with 5–10% (UK Help to Buy, US FHA loans), but a bigger deposit always means a smaller loan and lower lifetime interest.
A simple framework: spend ~50% of net income on needs, ~30% on wants, and save at least 20%. The budget tool above shows whether you're hitting that 20% — and if not, exactly how much to trim. Redirecting even one "wants" category toward your deposit can shave months off your timeline.
