The long promise of supporting a parent

Supporting a parent is rarely one number; it is a monthly cost plus a care reserve, repeated over years, and shared between people. Seen a month at a time it looks small; seen as a whole it is a real commitment. Enter the monthly amount, the yearly care reserve, the split, and how many years to project; the tool shows the first-year total, each person’s share, the running total, and what a bad medical year would do.

Result

At 4,000 a month plus 20,000 set aside for care each year, the first-year support total is about 68,000. Splitting with Person A taking 60%, Person A carries 40,800 and Person B 27,200. Over 10 years (simplified, no growth), the running total is about 680,000. If care spikes to 60,000 in some year, that year's total jumps to 108,000.

First-year total: 68,000
Person A carries: 40,800
Person B carries: 27,200
10-year running total (simplified): 680,000
Stress year (care spike): 108,000

The first-year total split by the agreed share; the numbers only show the split, not who is fairer.

The running total follows the figures and growth rate you enter; it is a projection, not a fixed cost.

Assumptions & limits

A growth rate makes the real commitment larger than the simplified total. Agree an emergency ceiling in advance, and count the labour of caregiving too. The tool shows the split; it does not judge who is fairer.
