One in three UK adults has done nothing to prepare for what happens to their money when they’re gone. And among those who have taken some steps, most haven’t finished the job. Thirty-eight per cent have written a will. According to Aegon, only 18% had organised the documents their family will actually need: pensions information, insurance details, account records.
Estate planning is easy to put off. It feels remote, complicated, a little morbid. But starting early creates options. You can make gifts during your lifetime. You can make tax-efficient decisions. You can know what you’re leaving behind, and why.
A cashflow model helps you do all of this with open eyes.
What cashflow modelling actually does
A cashflow model takes what you have today and projects how it might change over time. You put in your assets, your expected outgoings, your plans for when to draw on your pension. It uses assumptions to show you a range of possible futures.
It isn’t a guarantee. No model is. But it turns abstract questions into something you can see and work with. That’s when decisions get easier.
Here are five ways it can support your estate plan.
1. Understand what you can afford to give away now
Many people want to help family during their lifetime: a deposit for a first home, school fees for a grandchild, a boost to an adult child’s income. The worry is whether generosity today will leave a gap tomorrow.
A cashflow model shows you the likely impact of a gift on your long-term security. It moves the decision from gut feeling to informed choice.
2. Decide how to divide your estate
Knowing the projected value of what you’ll leave behind makes the conversation about inheritance more grounded. It gives you something concrete to work with, and gives your beneficiaries a clearer picture of what to expect.
3. Spot whether Inheritance Tax is something you need to plan for
Inheritance Tax applies to estates above certain thresholds. As your assets grow and change, it isn’t always obvious whether you’ll be affected. A cashflow model can flag this early, giving you time to explore ways to reduce a potential bill rather than leaving it to your beneficiaries to deal with.
4. Plan for care costs
The number of people in the UK who will need support with daily activities is expected to rise from 1.7 million in 2015 to 3 million by 2040. Care costs are a real and growing part of later life planning. A cashflow model helps you understand whether your plan can absorb them, and what adjustments might be needed.
5. Test “what if” before you commit
What happens to your estate if you increase your annual spending? What if you gift £25,000 to each of your children? What if you leave a percentage to charity?
A cashflow model lets you ask these questions before you act. You see the likely knock-on effects. You find the gaps. You move forward with confidence rather than hope.
