Down Payment Calculator (VND)
If you are living and working in Vietnam and thinking about buying property, the first number that matters is the down payment — the slice of the price you must put up in cash before a bank will finance the rest. Lenders here typically expect borrowers to cover 20–30% of the value themselves; the property secures the remaining loan. The bigger your down payment, the smaller the mortgage and the lighter the monthly repayment.
The arithmetic is straightforward: down payment = home price × down-payment percentage. For a 3.000.000.000 VND home at 30% down, that is 900.000.000 VND of cash you need ready. If you have already set aside 200.000.000 VND, the figure that actually governs your timeline is what is still to save: 700.000.000 VND.
From there the question is always how long. Putting away 15.000.000 VND a month into a savings vehicle at an illustrative 5%/year, this tool simulates the balance month by month and lands at roughly 41 months (~3.4 years). Two cautions for foreigners specifically: property-ownership rules and bank lending criteria for non-citizens differ from those for locals and change over time, so confirm your eligibility and required deposit with the bank directly — and treat every rate on this page as an illustrative assumption, not a quote.
How the calculator works
Three steps
- Down payment needed = home price × down-payment % ÷ 100. Example: 3.000.000.000 × 30% = 900.000.000 VND.
- Still to save = max(0, down payment − current savings). If you already hold more than the requirement, this is zero.
- Time to save = simulate the balance: each month add your contribution, then multiply by (1 + monthly rate) until you reach the target.
| Input | Meaning |
|---|---|
| Home price | The total price of the property you are targeting |
| Down-payment % | The share you fund yourself (the bank lends the rest) |
| Current savings | Cash/savings you already hold for this goal |
| Monthly saving | The amount you can set aside each month |
| Annual rate | Savings interest (illustrative), converted to a monthly rate |
Converting the annual rate
The tool turns the annual rate into an effective monthly rate: r_m = (1 + r_annual)^(1/12) − 1. At 5%/year, the balance grows about 0.407% each month. Each contribution is added at the start of the month and earns interest that same month — exactly the loop above, so you can reproduce every figure in the widget or a spreadsheet.
The no-interest case
If your savings sit somewhere that earns nothing, the time to save is simply the ceiling of (still to save ÷ monthly saving). In the main example that is 47 months; the illustrative 5%/year trims it to 41 months — about 6 months faster. Over a few years interest helps but is not decisive: consistent monthly saving moves the needle far more.
What the model leaves out
It assumes a constant savings rate, and ignores house-price inflation, taxes, notary and registration fees, and income changes. The required down-payment percentage is set by each bank based on your credit profile, and foreign-buyer rules add their own constraints. Treat the result as a planning scenario. To check whether your income can carry the remaining mortgage, pair this with FiMo's borrowing-power and DTI/LTI tools.
Worked example: a 3.000.000.000 VND home, 200.000.000 VND saved, 15.000.000 VND/month
Illustrative assumptions: a constant 5%/year savings rate, contributions at the start of every month. Comparing three common down-payment levels:
| Down payment | Down payment needed | Still to save | Bank loan | Time to save |
|---|---|---|---|---|
| 20% | 600.000.000 | 400.000.000 | 2.400.000.000 | 25 months (~2.1 yrs) |
| 30% | 900.000.000 | 700.000.000 | 2.100.000.000 | 41 months (~3.4 yrs) |
| 50% | 1.500.000.000 | 1.300.000.000 | 1.500.000.000 | 71 months (~5.9 yrs) |
Read the table as a trade-off. A 20% deposit gets you in soonest (just 25 months) but leaves the largest loan, 2.400.000.000 VND — more interest paid and a heavier monthly repayment. A 50% deposit stretches the saving phase to 71 months, but the loan shrinks to 1.500.000.000 VND, easing everything that follows.
The 30% level is the balance many buyers settle on: 900.000.000 VND of down payment, 700.000.000 VND still to save, about 41 months to get there. With savings earning nothing the same plan takes 47 months, so the illustrative 5%/year saves roughly 6 months. Once you have a loan figure, run FiMo's borrowing-power calculator to confirm your income can comfortably service the monthly repayment before you commit.
Frequently asked questions
How much down payment do I need to buy a home in Vietnam?
It depends on the bank and your profile, but Vietnamese lenders commonly expect you to fund 20–30% of the price yourself, financing the rest. For a 3.000.000.000 VND home: 20% is 600.000.000 VND, 30% is 900.000.000 VND, and 50% is 1.500.000.000 VND. A larger down payment means a smaller loan and a lighter monthly repayment.
How is the down payment calculated?
The formula is down payment = home price × down-payment % ÷ 100. Verifiable example: 3.000.000.000 × 30 ÷ 100 = 900.000.000 VND. The amount still to save is the down payment minus what you already hold — here 900.000.000 − 200.000.000 = 700.000.000 VND.
How long will it take to save the down payment?
For a 30% target (900.000.000 VND), with 200.000.000 VND already saved and 15.000.000 VND/month going in: at an illustrative 5%/year it takes about 41 months (~3.4 years). With savings earning nothing it is 47 months. Enter the rate you actually earn for a closer estimate.
Should I make a bigger down payment or borrow more?
It is a trade-off between waiting and debt load. A 20% deposit lets you buy soonest (about 25 months in the example) but leaves a 2.400.000.000 VND loan. A 50% deposit takes longer (71 months) but the loan is only 1.500.000.000 VND, with far less interest. The safe rule: put down enough that the monthly repayment fits your income — check that with FiMo's borrowing-power and DTI/LTI tools.
Can foreigners get a mortgage and buy property in Vietnam?
Property-ownership and lending rules for non-citizens differ from those for locals and change over time — some foreigners buy via specific ownership structures, and bank lending criteria for non-residents are stricter. This calculator handles the math of any down payment in VND, but you must confirm your eligibility, the required deposit and loan terms with the bank and a qualified advisor directly. Nothing here is legal or financial advice.
Are the interest rates here real bank rates?
No. The 5%/year used throughout is an illustrative assumption chosen to keep the math easy to verify. Actual VND savings and mortgage rates vary by bank, tenor and date. Check current posted rates and type your own number into the calculator — the formulas behave identically at any rate.
