Assumptions and conventions
- Pure arithmetic — no interest-rate convention applies to this tool.
- Closing costs are your estimate; local taxes and duties are not calculated automatically.
- Percentage presets are common conventions for the selected country, not eligibility rules.
- No mortgage-insurance thresholds or exemptions are applied.
- Values are calculated at full precision and rounded for display; columns may differ from totals by a small rounding amount.
Two ways to plan
Mode A starts from a property price: enter the price and a down payment (as an amount or percentage) and see the deposit, the resulting mortgage, the loan-to-value ratio, and the total upfront cash once closing costs are added. If you enter your available savings, it also shows what remains after the purchase and your reserve — or the shortfall.
Mode B starts from your cash: enter savings, the emergency reserve you refuse to touch, and estimated closing costs. What remains is your usable deposit, and with your target down-payment percentage the calculator works backwards to the maximum property price that deposit supports.
Why the reserve matters
Spending every unit of savings on the purchase leaves nothing for repairs, moving costs or emergencies in the very months they are most likely. Planning the reserve first — and only then sizing the deposit — is the discipline this tool encodes.
Formula
Mode A: deposit = price × percent (or the amount entered); mortgage = price − deposit; LTV = mortgage ÷ price; upfront cash = deposit + closing costs; remaining savings = savings − upfront cash − reserve.
Mode B: usable deposit = savings − reserve − closing costs; maximum price = usable deposit ÷ target down-payment fraction; mortgage = price − deposit.
Assumptions
- Closing costs are your estimate; taxes and duties vary by country and are not calculated automatically.
- Percentage presets are common conventions for the selected country, not eligibility rules.
- No mortgage-insurance thresholds or exemptions are applied — these vary by country and lender.
- Mode B assumes the whole usable deposit is used at the target percentage.

Worked example
Mode B: savings of 100,000, a 20,000 reserve, and 10,000 of estimated closing costs leave 70,000 usable. At a 20% target down payment that supports a price of 350,000 with a 280,000 mortgage at 80% LTV.
Mode A with a 400,000 price at 20% down needs an 80,000 deposit plus 12,000 closing costs = 92,000 upfront; with 100,000 of savings and a 15,000 reserve, the plan is 7,000 short — the calculator says so plainly instead of rounding it away.
Frequently asked questions
How much down payment do I need?
Conventions vary by country — the presets reflect common figures (for example 20% in many markets, less under various first-buyer schemes). Larger deposits mean smaller loans, lower LTV, and often better rates; the minimum you personally need is set by your lender and local rules, which this tool does not adjudicate.
Does a bigger down payment avoid mortgage insurance?
In several countries lenders require mortgage insurance above a certain LTV, so a bigger deposit can avoid it. Thresholds and schemes differ by country and lender, so this calculator reports your LTV without claiming eligibility either way.
What counts as closing costs?
Transaction taxes or duties, legal and valuation fees, lender fees, and registration charges — anything paid once at purchase. Enter your best estimate; local taxes are not calculated automatically.
How large should the emergency reserve be?
A common planning habit is three to six months of essential expenses, kept out of the purchase entirely. Mode B treats the reserve as untouchable and sizes the deposit from what remains.
What is loan-to-value and why does it matter?
LTV = mortgage ÷ property price. It is the lender's main risk measure: lower LTV usually unlocks better rates and, in some markets, avoids mortgage insurance.
