How to use this calculator
- Enter the exact funds requirement from your country's calculator — UK £1,529+fees, Canada C$22,895, Germany €11,904, and so on
- Pick a buffer based on how long the money will sit before your application date
- Pick your expected transfer cost honestly — bank wires with FX margin are the expensive default
- Read the recommended balance and build to that figure, not the bare minimum
- Re-check the live requirement figure before you convert — thresholds change
Every proof-of-funds number on this site is denominated in the destination country's currency, but most applicants earn and save in rupees, naira, rupiah or yuan. Between the day you convert and the day an officer reads your statement, the exchange rate moves — and it only has to move one way to turn a compliant balance into a shortfall of a few hundred pounds or euros.
The arithmetic is unforgiving because the requirement is a floor, not a target. A £20,000-style requirement met exactly, then hit by a 6% adverse move, is now £1,200 short — and top-up transfers take days and create exactly the 'large recent deposit' pattern that case officers question. The buffer is not extra money spent; it is the same money, converted with headroom.
Transfer costs compound the problem. Sending the equivalent of £20,000 through a bank that applies a 3% FX margin quietly consumes £600 before the money lands — and that cost is invisible until you compare the mid-market rate with what actually arrived. The fee difference between a bank wire and a specialist service on a typical student-sized transfer runs into hundreds of pounds per send, and most students transfer more than once.
A practical rule: convert early, convert once, and convert with 8-12% headroom. Funds that arrive early and sit still also solve the seasoning problem — every major visa regime (UK 28-day rule, Australia's deposit scrutiny, Canada's source-of-funds review) rewards money that has been quietly in place for months over money that appeared last week.
When the buffer matters most
Pairs with high volatility (many emerging-market currencies against GBP, EUR, AUD) routinely move 5-10% within a few months. If your home currency is volatile against your destination currency, treat the 12% buffer as the default, not the cautious option.
Keep the conversion record
The transfer receipt doubles as source-of-funds evidence: it shows where the money came from and when. Services that provide a clear statement of the converted amount and rate make the case officer's job easy — which is exactly what you want.
