A one-off amount, and a lot of opinions about it
A severance payment, an inheritance, a settlement or a sale arrives with pressure attached — from people with opinions, from your own sense that it should be doing something, and sometimes from whatever caused it. Parking it somewhere boring for a few weeks costs you almost nothing in interest and prevents the category of decision that gets regretted. Nothing about this money expires in a fortnight.
A balance at card rates costs you that much every year, guaranteed. Paying it off earns you exactly that, also guaranteed, with no risk. Nothing available to an ordinary person reliably beats it, and anything claiming to is taking risk it is not describing. Order by rate, highest first, and ignore the size of the balances — a small balance at 21% costs more each month than a large one at 4%.
Whatever else happens, some of it stays accessible. The purpose is not returns, it is that the next unexpected cost does not go back onto a card at the rate you just cleared. How much depends on your situation — how stable the income is, who depends on you — but committing all of it and leaving nothing is the most common and most expensive mistake with money like this.
After the expensive debt and the buffer, the remainder has genuinely different uses and no universally right answer. Lowering your monthly floor permanently — clearing a mortgage, buying somewhere outright — reduces what you need for the rest of your life. Producing income replaces a wage, if it clears its costs with somebody else running it. Holding it keeps every option open and loses ground to inflation. Which is right depends on whether you need certainty, freedom or time, and those are not the same thing.
Severance may be taxable in the year you receive it. An inheritance may have already been taxed at the estate, or may not. A settlement may be treated differently again. This varies by where you live and by the source, and it decides how much you actually have — which is worth one conversation with an accountant before anything is committed, though not a reason to delay working out what you want.
Money that arrives visibly tends to attract advice, some of it from people who are paid by what you choose. A fee-only adviser is paid for their time; a commission-based one is paid by the product. Both can be competent and only one has a reason to prefer certain answers. Asking how somebody is paid is a fair question and the answer tells you what to weigh.
It is one of the strongest options, especially if you want lower monthly costs rather than a bigger balance. Compare the mortgage rate to what you would realistically earn after tax, and count the certainty on the mortgage side — it is guaranteed, and it lowers what you need every month permanently.
A few weeks is usually enough to get past the initial pressure without drifting. Longer is fine. The only thing that should happen immediately is clearing debt at high rates, because that is costing you money every day it waits.
Fewer than you think. It is not secrecy so much as that unsolicited opinions about a lump sum are rarely about your situation. The people who need to know are the ones the decision affects.
If the amount is large or the tax position is unclear, one conversation with a fee-only planner or an accountant is money well spent. Ask how they are paid before you book, and be cautious of anyone who leads with a product rather than a question.
