1. Is the cash genuinely available?
Subtract upcoming bills, debt payments, planned transfers and protected goal contributions. Look far enough ahead to include irregular costs such as insurance, school fees and annual subscriptions.
2. What happens before the next income arrives?
Map the purchase onto a calendar. A decision can look affordable today but create a shortfall two weeks later. Variable or delayed income deserves a conservative assumption.
3. What happens to your emergency runway?
Calculate essential monthly expenses and see how many months remain after the purchase. Decide whether that result matches the stability of your income and responsibilities.
4. What is the total ownership cost?
The sticker price may be the beginning. Add finance costs, subscriptions, insurance, maintenance, delivery, setup, accessories and eventual disposal costs. For financed purchases, compare the total paid—not just the monthly instalment.
5. Which future goal moves?
Translate the purchase into time. Will the house deposit move by two months? Does retirement saving pause? Does a project lose its contingency? A purchase can be affordable and still be out of alignment with your priorities.
A useful answer is more than yes or no
The clearest outcomes are: safe, safe with conditions, high risk or not enough information. If the purchase is unsafe now, identify what would change the answer: a lower price, a later date, a larger buffer or a different payment method.
And when the numbers work, say so. Financial planning should create guilt-free permission to enjoy money—not only reasons to avoid spending.
