Retirement Planner (VND)
A retirement plan answers two questions, not one: how much will you have on the day you stop working, and how long will that money last before it runs out. The calculator above simulates both phases month by month — an accumulation phase while you are still earning and contributing, then a drawdown phase where you stop contributing and start living off the portfolio — so it tells you whether the money survives to age 100 rather than just printing a single net-worth figure.
If you are a foreigner living and working in Vietnam, a few realities sharpen the problem. You likely have no full Vietnamese state pension to fall back on, your savings and expenses are denominated in VND, and your horizon may include a repatriation or a move elsewhere — all of which make a self-funded plan, modelled honestly, more important than for a local with social-insurance coverage. On top of that, inflation erodes both ends: at an illustrative 4%/year, the 20.000.000 VND/month you would want to spend today balloons to roughly 78.921.780 VND/month by the time you turn 65, simply because the cost of living climbs for 35 years.
The gap between nominal and real value is the part most people underestimate. In the default scenario, the portfolio reaches 9.295.116.656 VND at age 65 — an impressive headline — but in today's purchasing power that is only about 2.355.526.363 VND. Enter your current age, target retirement age, current savings, monthly contribution, desired retirement spending, and your return/inflation assumptions; the chart plots both the nominal balance and the real (inflation-adjusted) value year by year and flags whether the plan is secure to 100 or runs short. Every rate here is an illustrative assumption for transparency — markets move, so stress-test a lower return too.
How the simulation works
Two phases, stepped monthly
The model loops month by month from your current age to 100, using a monthly rate equal to the annual return divided by 12.
Accumulation (age < retirement age): each month the balance earns interest, then the contribution is added:
`` new balance = balance × (1 + r/12) + monthly contribution ``
Drawdown (age ≥ retirement age): no more contributions; each month the balance earns interest, then one-twelfth of the annual spend is withdrawn. The annual spend is inflated from your current age:
`` annual spend = monthly spend × 12 × (1 + i)^(years from today) ``
| Symbol | Meaning |
|---|---|
| PV | Current savings |
| PMT | Monthly contribution (accumulation phase only) |
| r | Nominal annual return (illustrative 7% = 0.07) |
| i | Annual inflation (illustrative 4% = 0.04) |
| n | Years to retirement (= retirement age − current age) |
Real value and the "will it last?" flag
Each year the calculator divides the nominal balance by (1 + i) raised to the years elapsed to get the real value — purchasing power in today's VND, shown as the dashed line on the chart. The plan is judged secure if the portfolio is still positive at age 100; if the balance hits zero before then, the tool reports a shortfall and the age at which the money runs out.
Cross-checking against withdrawal rules
This model computes the cash flows directly rather than imposing a fixed withdrawal rate. To sanity-check against the 4% rule (withdraw 4% of the portfolio in year one, then adjust for inflation) or to back into a target nest egg, pair this with FiMo's retirement withdrawal calculator and Coast FIRE tool.
What the model leaves out
It assumes a constant return and constant inflation for life, ignores taxes, fees and any social-insurance pension, and assumes you withdraw exactly as planned. In reality returns vary, and a run of poor returns early in retirement (sequence-of-returns risk) can change the outcome materially. Treat the output as a scenario, not a guarantee.
Worked example: retire at 65, starting at age 30
Illustrative assumptions: a constant 7%/year return and 4%/year inflation for life, level monthly contributions until retirement, then withdrawals at an inflation-adjusted spend.
| Input | Value |
|---|---|
| Current age → retirement age | 30 → 65 (35 years of accumulation) |
| Current savings | 50.000.000 VND |
| Monthly contribution | 5.000.000 VND |
| Desired spend (today's value) | 20.000.000 VND/month |
| Return / inflation (illustrative) | 7% / 4% per year |
Portfolio by age milestone:
| Age | Nominal balance | Real value (today's purchasing power) | Phase |
|---|---|---|---|
| 40 | 1.097.695.535 | 741.563.772 | Accumulating |
| 50 | 3.071.420.358 | 1.401.756.158 | Accumulating |
| 60 | 7.037.938.902 | 2.169.927.947 | Accumulating |
| 65 | 9.295.116.656 | 2.355.526.363 | Retire |
| 70 | 6.846.181.563 | 1.425.984.617 | Drawing down |
Over 35 years you pay in 2.150.000.000 VND (starting capital plus contributions), and the portfolio compounds to 9.295.116.656 VND by age 65 — most of it interest. But in today's purchasing power that is only 2.355.526.363 VND, which is the number that actually matters.
The catch: the desired spend of 20.000.000 VND/month (today's value) has been inflated to 947.061.359 VND for the first year of retirement alone. At that withdrawal rate the portfolio lasts only 12 years and runs dry at age 77 — short of 100. The tool shows a red "shortfall" warning.
Closing the gap
| Lever | Change | Result |
|---|---|---|
| Spend less | 8.000.000 VND/month (today's value) instead of 20.000.000 | Money lasts past age 100 ✓ |
| Save more | 10.000.000 VND/month instead of 5.000.000 | Age-65 portfolio reaches 18.951.381.576, lasts to age 96 |
Trimming the target spend to 8.000.000 VND/month (today's value) flips the plan from "runs dry at 77" to secure for life. That is the value of running scenarios: nudge each input and watch the safety line move before you commit to a number.
Frequently asked questions
How much do I need to retire in Vietnam?
There is no single number — it depends on the lifestyle you want, your retirement age and your life expectancy. In the calculator's default scenario (retire at 65, spend 20.000.000 VND/month in today's money, illustrative 7%/year return and 4%/year inflation), a 9.295.116.656 VND portfolio at age 65 still only lasts to age 77. The right approach is to enter your own target spend and let the tool tell you whether the plan is secure or runs short.
Why does my retirement balance look huge but its real value is small?
Inflation. A nominal balance of 9.295.116.656 VND at age 65 (default scenario), discounted to today's purchasing power at the illustrative 4%/year, is worth only about 2.355.526.363 VND. The dashed "real value" line on the chart is the figure to judge by, because it tells you how many of today's goods that money could actually buy.
As a foreigner in Vietnam, can I rely on a state pension for retirement?
Generally not a full one — which is why a self-funded plan modelled honestly matters more. This calculator assumes no pension income and projects purely from your own savings and contributions. If you do expect some social-insurance or home-country pension, treat it as a supplement that lowers the draw on your portfolio: enter only the shortfall you need the portfolio to cover, not your total spending.
How does the planner decide if my money lasts to 100?
It simulates every month from your current age to 100. While working, each month adds interest then your contribution. In retirement, each month adds interest then subtracts your spend (inflated from today). If the balance is still positive at age 100, the plan is flagged secure; if it hits zero first, the tool reports the age the money runs out — for example the default scenario runs dry at age 77.
Should I contribute more or spend less to fix a retirement shortfall?
Both work, differently. In the default scenario (runs dry at 77): spending less — 8.000.000 VND/month in today's money — makes the money last past 100; contributing more — 10.000.000 VND/month — lifts the age-65 portfolio to 18.951.381.576 VND and stretches it to age 96. Spending cuts hit the drawdown phase immediately, while extra contributions compound over many years before they pay off.
Are the 7% return and 4% inflation in the examples real figures?
No. The 7%/year return and 4%/year inflation are illustrative assumptions chosen to make the math easy to verify, not forecasts of Vietnamese markets or inflation. Real investment returns swing widely and inflation varies by period. Substitute your own assumptions — and always test a lower-return scenario to see whether the plan still holds.
What is the 4% rule and does this tool use it?
The 4% rule suggests withdrawing 4% of your portfolio in year one, then adjusting for inflation each year, with the aim of the money lasting roughly 30 years. This planner does not impose a fixed rate; it computes the drawdown directly from the spend you enter, which is more flexible but also more sensitive to assumptions. To cross-check against the 4% rule or to back into a target nest egg, use FiMo's retirement withdrawal calculator alongside this one.
