Understand the quick screening rule before you apply
A visa application can feel complicated because official requirements are rarely captured by a single number. Consulates may ask about your purpose of travel, how long you plan to stay, whether you can support yourself financially, and whether you meet the rules for an adult applicant or a minor. This page does not try to replace those official requirements. Instead, it gives you a fast first-pass screening rule so you can answer one practical question before you start gathering documents: based on age and available money, do your basic inputs look strong enough for a very simple visa-style funding check?
That is why the calculator focuses on only three facts: your age, the amount of money you can document in US dollars, and the number of days you expect to stay. Those are easy to estimate early in the planning process, and together they produce a useful rough answer. If the result is favorable, you know your travel plan clears this page's simplified threshold. If the result is unfavorable, you immediately know where the pressure point is. Usually the fix is obvious: shorten the trip, increase documented funds, or confirm whether a different visa category or guardian-based application process applies.
This framing matters because many online tools are vague. They tell you to enter values, click a button, and trust the result without explaining what the numbers mean or what the output actually says. A better calculator should do more than compute. It should explain the rule in ordinary language, show how the numbers connect, and make it easy to test realistic scenarios. That is the goal of this page.
What this checker actually measures
The rule here is intentionally narrow. The calculator marks a case as eligible only when both of the following are true: the traveler is at least 18 years old, and the traveler has at least $100 for every planned day of travel. In other words, the tool assumes that an adult visitor should be able to show a minimum daily budget for the entire stay. It is a simple screen, not a full legal determination.
That distinction is important. Real visa systems often consider many more details: nationality, destination country, passport validity, onward travel, accommodation, sponsorship, travel purpose, interview responses, previous immigration history, criminal background, medical documentation, family ties, and local embassy policy. None of that appears in this quick model. So an eligible result here means only that your entered age and funds pass this page's basic rule. It does not mean that a specific embassy will approve your application.
Even with that limitation, the calculator can still be genuinely useful. Travelers often use a quick screen like this at the planning stage. You may be deciding whether a two-week trip is financially realistic, whether a bank balance is likely to look thin, or whether extending the stay by another week would push you below a comfortable documentation threshold. In those situations, a transparent preliminary rule is often more helpful than a vague checklist.
What each input means in practice
Your Age is entered in full years. In this calculator, age is used only as a simplified adult-screen threshold. If you are 18 or older, you pass the age portion of the check. If you are younger than 18, the tool marks the case as not eligible under this model because it assumes an independent adult traveler. That does not mean minors can never travel. It simply means they often need additional documentation such as parental consent, guardian information, or a different application structure that this calculator does not model.
Funds Available (USD) should be the amount of money you can reasonably document for the trip in US dollars. Think in terms of bank balances, readily available cash equivalents, or other proof a visa officer might actually accept in principle. This is not the place to count highly uncertain future income or informal promises of support unless those are documented and recognized in the process you are following. If your records are in another currency, convert them carefully before entering the value so the result is meaningful.
Trip Duration (days) is the planned length of stay. Enter the total number of calendar days for the visit that the funds are meant to cover. The calculator treats every day the same, which keeps the math simple. In reality, some travelers spend more in the first few days, others have prepaid accommodation, and some have local sponsors. Those details may matter in real applications, but this tool uses one flat daily funding rule so you can see the effect of duration immediately.
Notice how these inputs work together. Age is a gate. Funds and trip length form a budget relationship. If the trip gets longer while funds stay the same, the case becomes harder to support because the required amount rises one day at a time. If funds increase while the trip length stays fixed, the case becomes easier because your documented financial cushion improves. That cause-and-effect pattern is exactly what makes the calculator useful for scenario testing.
How the math works
The funding requirement is straightforward: multiply the planned number of days by $100. That gives the minimum funds required by this model. Then compare your available funds against that number, while also checking whether the traveler is at least 18 years old.
So if you plan to stay for 14 days, the model expects at least $1,400. If you plan to stay for 30 days, it expects at least $3,000. The relationship is linear, which makes the result easy to interpret. Every extra day adds another $100 to the requirement. If your funds are already close to the threshold, even a short extension can change the outcome.
The two MathML blocks below express the same idea in a more general modeling language. They were already part of this page and are preserved because they show how a calculator can be viewed abstractly as a function of several inputs, or as a sum of weighted contributions in more complex screening systems.
For this specific tool, though, you do not need a complicated weighted model. The logic is just a threshold check. That simplicity is a strength. It makes the result easy to audit in your head. You should always be able to look at your trip length, multiply by 100, and see whether your funds are above or below the line.
Worked examples you can follow without guessing
Suppose you enter an age of 25, available funds of $5,000, and a trip duration of 14 days. First compute the required funds: 14 × 100 = 1,400. Next compare your actual funds: $5,000 is greater than $1,400. Because the traveler is also at least 18, this scenario is marked eligible. The result is not subtle. The traveler clears both conditions with a comfortable margin.
Now change only one input. Keep the same age of 25 and the same 14-day trip, but reduce available funds to $900. The required amount is still $1,400, because the duration did not change. This time $900 is below the threshold, so the result becomes not eligible. That shift is useful because it shows exactly what the calculator is sensitive to. The traveler did not suddenly become ineligible for every possible visa in the real world; rather, the entered funds do not satisfy this page's simplified funding rule for that trip length.
A third example shows why the age field matters. Imagine a traveler who is 16 years old, has $4,000 available, and plans to stay for 7 days. The funding check passes because 7 × 100 = 700 and $4,000 is above that amount. However, the age condition fails because the traveler is under 18. The calculator therefore returns not eligible under this model. That is a prompt to review guardian consent and minor-traveler rules, not a statement that travel is impossible.

These examples are more than illustrations. They are a practical self-check. If the calculator gives you an answer that does not match the logic in a simple example, the first thing to inspect is usually your input meaning. Did you enter the total trip days or only hotel nights? Did you convert funds into US dollars? Are you testing an adult application or a minor's case? Good interpretation is just as important as correct arithmetic.
How to read the result panel
The result message is deliberately short. If the checker returns Eligible, it summarizes the age, the entered funds, and the funding requirement calculated from the trip length. That message is meant to be easy to copy into travel notes or a planning email. If the checker returns Not eligible, the message tells you the minimum amount needed for the trip duration you entered. In other words, the result is not just a pass-fail signal; it also tells you the threshold you missed.
When interpreting the output, ask two practical questions. First, does the threshold itself make sense? A 10-day trip should require $1,000. A 40-day trip should require $4,000. If the funding requirement surprises you, it may simply be reminding you how quickly trip length changes the budget. Second, is your entered funds number realistic as a documented amount? A rough idea in your head is not the same as a balance you can actually support with records. The calculator is only as useful as the credibility of the number you enter.
The optional Copy Result button appears after a successful calculation. That is handy if you are comparing versions of the same plan. For example, you can run a 10-day scenario, copy it, then run a 14-day scenario and compare the required funds side by side. Small workflow features like that make the calculator easier to use for planning rather than as a one-off novelty.
Assumptions, limits, and the safest next step
This page makes several simplifying assumptions. It uses a flat daily funding rate of $100. It assumes all funds are measured in US dollars. It does not distinguish between prepaid accommodation and unspent cash, and it does not recognize sponsorship letters, invitation letters, or family support. It also treats age 18 as the adult threshold for the whole model. Those assumptions are not universal legal rules. They are design choices for a quick estimator.
Because of those limits, the safest way to use the calculator is as a planning tool rather than an authority. If you are near the threshold, test two or three scenarios instead of trusting a single run. Try the shortest realistic trip, the most likely trip, and a slightly longer trip. If you are converting from another currency, round conservatively so you do not overstate your resources. If a minor traveler is involved, treat the result as a prompt to research child-specific documentation requirements immediately.
The most helpful habit is simple: use the calculator to reveal the structure of the decision. The structure here is clear. Age must meet the adult threshold, and funds must scale with days at $100 per day. Once you see that relationship, you can make better travel plans, spot weak assumptions early, and prepare sharper questions for the official visa source you ultimately rely on.

Tip: if you are planning around a tight budget, try one shorter stay and one longer stay. Because the rule is $100 per day, even a small change in duration can move the result.
