A single parent's term ladder, matched to each child's age
A step-by-step worksheet that sizes layered term policies for a single parent with children aged 3 and 9, with the arithmetic and the premium trade-off.
A single parent's need for life insurance is not flat. It is highest today, when both children are young and every year of support is still ahead, and it falls as each child nears independence. A term ladder matches that shape: several term policies with different lengths, so the total coverage steps down as the need does. This worksheet builds one for a hypothetical parent with children aged 3 and 9, shows each calculation, and leaves blanks for you to repeat it with your own numbers.
All names, dollar figures and premiums below are invented to show the method. They are not prices, and an insurer's real quotes will differ. For the general idea of laddering, see the laddering term life policies to match your needs guide; for the single-parent basics, see life insurance for single parents.
The household in the example
Say Jordan is 36, a single parent, and earns $55,000 a year. Jordan's children are Theo, 9, and Mia, 3. Jordan's sister has agreed to be their guardian if Jordan dies. Jordan has $15,000 in savings and a group life policy through work equal to one year's salary, $55,000. Jordan has no other coverage.
Jordan does not want to guess at a single big number. The plan is to size the need year by year, then cover it with layers.
The worksheet, step by step
Six steps take the household from raw costs to a set of policies.
Step 1: Decide what the money is for
A parent's death creates four kinds of cost for the household that takes over. Write down which apply.
- Annual support: the added cost of raising each child in the guardian's home, including child care while they are young.
- College or training: a share Jordan wants to cover.
- A cushion for the guardian: a one-time sum for a bigger car, a bedroom or time off work.
- Final expenses and debts: so they do not come out of the children's share.
Jordan fills in the numbers.
| Item | Jordan's estimate |
|---|---|
| Annual support per child | $15,000 |
| College help per child | $40,000 |
| Cushion for the guardian | $25,000 |
| Final expenses and debts | $20,000 |
The $15,000 a year is a judgement call: it covers food, clothing, activities, health costs and a share of housing, with extra for child care in the early years. Your figure depends on where you live and what the household will need. Child care prices in particular vary widely by state; the guardian funding post and the How much life insurance do I need? guide discuss how to estimate them.
Step 2: Count the years each child still needs support
Support runs until each child turns 18. College help is a separate lump sum, needed when each child reaches 18.
| Child | Age now | Years to 18 |
|---|---|---|
| Theo | 9 | 9 |
| Mia | 3 | 15 |
Add them to get total child-years: 9 + 15 = 24. If you have more children, add a row for each.
Step 3: Compute the need at the start
Now compute what would be needed if Jordan died today.
- Support: 24 child-years x $15,000 = $360,000
- College: 2 children x $40,000 = $80,000
- Cushion: $25,000
- Final expenses and debts: $20,000
Total: $360,000 + $80,000 + $25,000 + $20,000 = $485,000.
Subtract what is already available. Jordan's savings are $15,000 and the group life policy is $55,000, for $70,000 in offsets. Net need today: $485,000 - $70,000 = $415,000.
Two cautions about the offsets. Group life usually ends when the job does, and the conversion window is short, often about 31 days, so Jordan should not treat it as permanent. And the net need does not subtract any Social Security survivor benefits the children might receive. That is a margin of safety; the Social Security survivor benefits and the $255 death payment guide shows how to look up an estimate from your own Social Security statement. Savings are also finite and may be needed by the guardian right away.
Step 4: Build the need curve
The need is not the same in every year. As Jordan's children grow, years of remaining support shrink. Compute the net need at several points in time, as if Jordan died in that year. The fixed items (cushion and final expenses, $45,000 here) are kept for the whole period for simplicity. College sums stay until each child reaches 18.
| Years from now | Theo's years left | Mia's years left | Support left | College left | Fixed | Offsets | Net need |
|---|---|---|---|---|---|---|---|
| 0 | 9 | 15 | $360,000 | $80,000 | $45,000 | -$70,000 | $415,000 |
| 5 | 4 | 10 | $210,000 | $80,000 | $45,000 | -$70,000 | $265,000 |
| 8 | 1 | 7 | $120,000 | $80,000 | $45,000 | -$70,000 | $175,000 |
| 10 | 0 | 5 | $75,000 | $40,000 | $45,000 | -$70,000 | $90,000 |
| 12 | 0 | 3 | $45,000 | $40,000 | $45,000 | -$70,000 | $60,000 |
| 15 | 0 | 0 | $0 | $0 | $45,000 | -$70,000 | $0 |
How each row is calculated, using year 5 as the example: Theo has 9 - 5 = 4 years left and Mia has 15 - 5 = 10, so 14 child-years x $15,000 = $210,000. At year 5 Theo is 14 and Mia is 8, so both college sums are still ahead, $80,000. Add the fixed $45,000 and subtract the $70,000 offsets: $210,000 + $80,000 + $45,000 - $70,000 = $265,000.
For year 10, Theo is 19, so his support and college sums have dropped out. Mia has 5 years left, 5 x $15,000 = $75,000, plus her college $40,000, plus $45,000 fixed, minus $70,000 = $90,000.
By year 15, Mia is 18 and the net need is zero, because the savings and group coverage offsets are larger than the $45,000 left.
The shape is a line sloping down from $415,000 to near zero over 15 years. A single level policy that pays $415,000 for 15 or 20 years covers the early peak but is far more coverage than Jordan needs later.
Step 5: Choose layers
A ladder cuts the line into steps using policies of different lengths. A common method:
- Pick the longest term. Size it to the need at the end of the next shorter term.
- Pick the next term. Size it to cover the need at the end of the one shorter than that.
- Make the shortest layer cover the rest of the peak.
Jordan's choices:
| Layer | Term | Face amount | Covers |
|---|---|---|---|
| A | 20 years | $50,000 | Final expenses and a margin until Mia is 23 |
| B | 15 years | $50,000 | The tail to Mia's 18th birthday |
| C | 10 years | $315,000 | The early peak, to Theo's 19th birthday |
Total at the start: $50,000 + $50,000 + $315,000 = $415,000, matching the net need.
Check each stage against the curve:
- Years 0 to 10: all three layers, $415,000. The need is $415,000 at the start and falls to $90,000, so the coverage is at or above it throughout.
- Years 10 to 15: layers A and B, $100,000. The need over this period runs from $90,000 down to $0. Covered.
- Years 15 to 20: layer A, $50,000. The need is final expenses and a margin.
The 10-year layer drops off in year 10, when Theo has been an adult for a year and Mia is 13. The 15-year layer drops off when Mia turns 18.
Step 6: Compare the cost with one level policy
Premiums are where the ladder pays off, and also where an illustration can mislead. These monthly rates per $100,000 are invented round numbers for a healthy 36-year-old, and real prices do not scale evenly with the amount.
- 10-year term: $9 a month per $100,000
- 15-year term: $11 a month per $100,000
- 20-year term: $13 a month per $100,000
One level policy: $415,000 for 20 years = 4.15 x $13 = $53.95 a month. Over 20 years: $53.95 x 12 x 20 = $12,948.
The ladder:
- Layer A: 0.5 x $13 = $6.50 a month
- Layer B: 0.5 x $11 = $5.50 a month
- Layer C: 3.15 x $9 = $28.35 a month
- Total in years 1 to 10: $6.50 + $5.50 + $28.35 = $40.35 a month, or $40.35 x 12 x 10 = $4,842
- Years 11 to 15: $6.50 + $5.50 = $12.00 a month, or $12.00 x 12 x 5 = $720
- Years 16 to 20: $6.50 a month, or $6.50 x 12 x 5 = $390
Total over 20 years: $4,842 + $720 + $390 = $5,952.
The difference is $12,948 - $5,952 = $6,996 in premiums over 20 years, and the monthly bill is $13.60 lower in the first decade. That gap exists because the ladder pays for coverage only while it is needed.
Real quotes will move these numbers. Many insurers set a policy fee, charge more per dollar for smaller policies, or have minimum face amounts. Three small policies may each carry a fee. Ask the agent or use the term life ladder builder to test real quotes. A very small layer might cost more per dollar than the table suggests, so the savings may be smaller than shown.
What the ladder gives up
A ladder is not free of risk, and a fair worksheet has a column for it.
- Coverage ends on schedule. If Jordan has another child, remarries or adopts, the need can go up. A single large policy would still be there, but a ladder has already stepped down.
- Three policies mean three sets of paperwork. Some insurers will underwrite several applications together; ask. All three need the same beneficiary plan, and the contingent beneficiary on each should be checked.
- Health can change. If Jordan develops a condition, buying a new policy later at the same price may not be possible. The conversion privilege on a term policy lets you change it to permanent coverage without new medical questions, but it usually has a deadline tied to the policy's age. Read the conversion clause on the longest layer first.
- The need may not be the same as the guess. The $15,000 per child per year is an estimate. If the guardian's household has higher costs, all layers rise.
- The end of the term is the end of coverage. Jordan will be 56 when layer A ends, at an age when new coverage is expensive. If Jordan wants coverage to last, a permanent policy or a conversion is a separate decision; see the choosing a term length around your child's college date post for a related length calculation.
An alternative is decreasing term insurance insurance, where the death benefit falls each year. It tracks a loan balance well and a child-raising need poorly, since its death benefit is the lowest when the children's college bills arrive. The level term vs decreasing term life insurance guide compares them.
Stress test: what if the group coverage goes away
Jordan's plan leans on a $55,000 group policy that belongs to the employer. A layoff, a job change or a plan change would remove it, and the conversion price for group coverage is often high. A sound worksheet runs the numbers without it.
Without the group policy, the offsets fall from $70,000 to $15,000 (the savings only). The net need at the start rises by $55,000: $485,000 - $15,000 = $470,000. At year 10 the need becomes $90,000 + $55,000 = $145,000, and at year 15 it becomes $45,000 - $15,000 = $30,000 rather than zero.
Jordan can respond in two ways. One is to enlarge the layers now: raise layer C from $315,000 to $370,000, and layers A and B to cover the $145,000 at year 10 and the $30,000 at year 15. The other is to keep the smaller ladder and promise to re-run the worksheet the day the job changes. The first costs more every month; the second costs less but depends on Jordan being healthy enough to buy new coverage on that day. Neither is wrong. They are different bets, and writing both down helps a parent choose with the cost in front of them.
Other things that change the answer
The example is deliberately plain. Real households add complications, and each one moves a number in the worksheet.
- Children close in age. With ages 9 and 11, the peak is lower and the two sets of years nearly overlap, so one or two layers may do. Ages 3 and 9 are far enough apart that the tail from the younger child is long.
- A child with ongoing needs. If either child will need support past 18, the ladder's end date is wrong, and the choice moves toward longer or permanent coverage and a different kind of beneficiary arrangement. The plan for a child with a disability is its own subject.
- A guardian who earns little. If the sister would have to cut her hours to take in two children, the cushion line should be much larger than $25,000. The cushion is the cheapest line to underestimate.
- A second adult. If Jordan remarries, the other adult's income changes the support line, and the beneficiary choices change too. Re-run the sheet after any such event.
- Inflation. The $15,000 a year is at current prices. Costs rise, so a 15-year layer sized to today's prices buys less at the end. The ladder's shape leaves some room, because the early layers are the largest, but a parent can add a percentage to the support figure to cover it.
Review dates
A ladder is not a permanent decision. Put three dates on the calendar.
- Each birthday of the older child, or each year on the policy anniversary: compare the remaining layers with the need curve for the next five years.
- After any life event: a new child, a marriage, a new job, a move, a change in the guardian.
- Two years before the longest layer ends: decide whether to let it expire, convert it or replace it. Conversion rights often end before the term does.
The How long a term do I need? and the term life ladder builder both let you try different layer lengths against your own figures.
Who receives the money
A ladder answers how much and for how long. It does not answer who holds the money for two minors. An insurer will not pay a minor directly, and a court may supervise an arrangement that Jordan did not choose. Name a trust or a custodian for the children's benefit, with Jordan's sister or another adult as trustee; see naming a minor child as life insurance beneficiary for how this works. That choice is separate from naming a guardian, which belongs in a will.

If you have a different number of children, add rows. If your children's ages are closer, the peak is lower and the ladder is shorter. If you are comparing a ladder with one policy, get real quotes for both on the same day.
Key takeaways
- A single parent's net need is highest today and falls as each child nears 18; a ladder of terms of different lengths follows that slope.
- Total the years of support, college, a guardian cushion and final expenses, then subtract savings and existing coverage; in the example that gave $415,000.
- Cutting the need into 20-, 15- and 10-year layers covered the same peak at lower illustrative cost, $5,952 against $12,948 over 20 years, but real prices rarely scale that evenly.
- A ladder steps down on schedule, so it carries the risks of a new child, a changed health picture and a conversion deadline.
- Name a trust or custodian for minor children and a guardian in a will; the policy alone answers neither.
