Prepay a Funeral, Pay Down a 7% Mortgage, or Hold Stocks? The 10-Year Math for Burial, Cremation, Green Burial and Aquamation

It's Wednesday, September 30, 2026. You have $12,800 in savings that you think of as "my burial fund." You could hand it to a funeral home today for a price-locked plan. You could put it toward a mortgage, leave it in a CD, or keep it in the market.

Short version: a price-guaranteed prepaid plan earns, in effect, the funeral inflation rate. It beats a taxable CD. It loses to any debt that costs more than funeral inflation. It's a coin-flip against stocks that depends on when you need the money. And the disposition method you pick moves more dollars than any of those choices.

Below is the math, with the caveat that every input is an example. Your numbers will differ.

What this week's data says (and doesn't say)

I read five articles for this post. Here is what each one contributes.

  • Bureau of Labor Statistics, "Major Economic Indicators Latest Numbers": CPI +0.4% in August 2026, unemployment 4.1%, payroll employment +162,000 (preliminary), average hourly earnings +$0.10 (preliminary). Prices rose 0.4% in a month, and wages rose a dime an hour. I won't turn the dime into a percentage because I don't have the base figure in front of me.
  • NerdWallet, "Mortgage Rates Today, Wednesday, September 30: Steadily Above 7%": rates are in a holding pattern and inflation is "still running hot."
  • Mr. Money Mustache, "Will the AI Bubble Destroy our Retirement?": the market keeps surprising us, whether it crashes or hits records. I'm borrowing that premise. I'm not summarizing his retirement argument, so read it yourself.
  • Two NerdWallet sponsored card pieces (the IHG Premier card and Bilt's new launch): I don't have their terms, so I'm not modeling them. One point does apply. Putting a funeral on a rewards card only works if you pay it off in full. Carried-balance interest will swamp any points (see our credit card vs. prepaying breakdown).

None of this forecasts what happens over the next decade. It shows that cash has high-yield alternatives right now (7%-plus debt), that prices are moving, and that stocks are a wild card. That is enough to set up the comparison.

The one-line formula

Assume a prepaid plan that is truly price-guaranteed, with no premium and no fees. Then prepaying earns the funeral inflation rate on your money. Any alternative has to beat that rate, after tax, at the moment of need, to come out ahead.

My example inputs:

  • Prices (from our four-way 2026 price comparison): burial $12,800, cremation $2,695, green burial $5,200, aquamation $3,200
  • Funeral inflation: 3.7% a year (an assumption, not a forecast)
  • CD: 4.2% pre-tax, 22% bracket, so 4.2 × 0.78 = 3.28% after tax (more on this in our CD after-tax piece)
  • Mortgage payoff: 7%, in line with the NerdWallet headline
  • Stocks: 8% a year, purely illustrative
  • Horizon: 10 years

Prices grow by 1.037¹⁰ = 1.4381 over ten years:

MethodPrice todayPrice in 10 years at 3.7%
Traditional burial$12,800$18,408
Green burial$5,200$7,478
Aquamation$3,200$4,602
Cremation$2,695$3,876

Where the same money could go

Each cell shows the net advantage of not prepaying after 10 years. A plus means the alternative wins. A minus means prepaying wins.

MethodCD (3.28% after tax)Mortgage payoff (7%)Stocks (8% smooth)Stocks (8%, one −30% year)
Burial−$732+$6,772+$9,227−$497
Green burial−$297+$2,751+$3,748−$202
Aquamation−$183+$1,693+$2,307−$124
Cremation−$154+$1,426+$1,943−$105

Three things stand out.

  1. The CD loses to prepaying every time. 3.28% after tax is below the 3.7% inflation assumption. The gap is small on cremation ($154) and more noticeable on burial ($732).
  2. A 7% mortgage paydown beats prepaying by a lot on burial. The $6,772 edge is the headline number, and it comes with a big condition, covered below.
  3. Stocks look great in the smooth column and only slightly worse than prepaying in the crash column. That is because nine years of growth cushion a late drop. The next section shows what happens when the need comes early.

This is the kind of analysis Zelovari runs for you, so you don't have to build the spreadsheet yourself.

The table also shows that the method matters more than the funding. Burial costs $10,105 more than cremation today ($12,800 − $2,695). Ten years on, that gap is $14,532 ($18,408 − $3,876). The funding decision moves $732 to $6,772 on burial and only $105 to $1,943 on cremation.

Stress test 1: what if August's 0.4% is the new normal?

One month isn't a trend, and CPI covers all items, not just funerals. But if 0.4% a month persisted, it compounds to about 4.9% a year (1.004¹² ≈ 1.049). Here is the burial math at three inflation rates:

Funeral inflationBurial price in 10 yrsCD (3.28%) vs. prepayMortgage (7%) vs. prepay
3.0%$17,202+$473+$7,977
3.7%$18,408−$732+$6,772
4.9%$20,652−$2,977+$4,527

The CD flips from slightly ahead to $2,977 behind as inflation rises. The mortgage paydown stays ahead in all three cases. It wins because 7% is a guaranteed return, not because inflation is low.

Stress test 2: what if you die in year 2, not year 10?

Nobody picks the date. Here is the same $12,800 burial with two possible timings. Prepaying is $0 by design, since the price is locked and the contract is honored.

Where the money sitsNeed in year 2Need in year 10
CD (3.28%)−$111−$732
Mortgage payoff (7%)+$890+$6,772
Stocks (8%, one −30% year)−$4,088−$497

The stock row is the lesson from Mr. Money Mustache's premise. A funeral is a bill with an unknown due date and a price that keeps rising. Holding it in an asset that can fall 30% is a bet on the date you die. A crash before the need leaves a $4,088 hole in year 2, because 12,800 × 1.08 × 0.70 = $9,677 against a $13,765 price. That doesn't make stocks wrong. A long horizon and a large portfolio can absorb this. A dedicated $12,800 cannot.

You can model your own timing, tax bracket and return assumptions at Zelovari. The AI-bubble break-even post walks through the market-drop case in more detail.

The mortgage caveat most comparisons skip

The NerdWallet headline is about what a new borrower pays. Paying down your loan earns your rate.

  • If your mortgage is 7% or higher, or the money would retire a HELOC or card balance at that level, the paydown is very hard to beat.
  • If your mortgage is 3.5%, paying it down earns 3.5%. Over 10 years, 1.035¹⁰ = 1.4106 turns $12,800 into $18,056, which is $352 short of the $18,408 burial price. Prepaying wins narrowly.

There is also a liquidity problem. Paying down a mortgage doesn't put cash in your family's hands when they need it within days. They'd need a HELOC, a refinance, or a sale, and lenders don't move at funeral speed. Our head-to-head on mortgage payoff vs. prepaying covers that trade-off.

Insurance-funded vs. trust-funded: the contract clause that moves the answer

I've assumed a true price lock. Many plans don't work that way.

  • Trust-funded: your money sits in a trust, and growth is typically taxable to you. That is the 3.28% after-tax logic above. Refund and transfer terms vary by state and contract.
  • Insurance-funded: a policy's death benefit is assigned to the funeral home. The key question is how fast the benefit grows.

Here is an example. Suppose an insurance-funded plan's benefit grows 3% a year while the burial price grows 3.7%. Then 1.03¹⁰ = 1.3439 turns $12,800 into $17,202, which is $1,205 short of the $18,408 price. Read whether the contract guarantees the goods and services or only a dollar amount. Our insurance vs. trust comparison shows where the gap comes from.

Two variables that change the inputs

VA benefits. Eligible veterans can be buried in a national cemetery, with the gravesite, opening and closing, and headstone covered. Suppose $4,200 of the $12,800 burial consists of items the VA covers. That figure is a placeholder, so use your funeral home's itemized price list. Then you would lock in $8,600, not $12,800. The ten-year inflation you'd be guarding against drops from $5,608 to $3,768 (8,600 × 1.4381 = $12,368). Don't prepay items you may get free. See our VA benefits breakdown for detail.

Medicaid. In many states, money in an irrevocable preneed funeral contract is treated as exempt. The same money in a CD or brokerage account is usually a countable asset. If long-term care is a realistic risk in the next few years, the CD's "3.28%" may be a number the spend-down rules never let you earn. Exemption rules, caps and look-back treatment vary by state, so confirm with an elder-law attorney. The cost of irrevocability is flexibility if you move or change your mind.

A quick decision grid

Debt at 7%+ and adequate liquidity elsewherePay down the debtA guaranteed 7% beats 3.7% inflation
Mortgage near 3–4%, cash in a taxable CDPrepay (price-guaranteed)The CD's after-tax yield is below funeral inflation

Eligible veteranPrepay only what the VA won't coverAvoid paying twice
Cremation or aquamationThe funding decision matters littleGaps are $105 to $1,943 in the table

Prepaying isn't always right. Any contract with a premium, fees or weak refund terms lowers its effective return. Staying flexible is also a legitimate choice if your health, location or finances are uncertain.

Your numbers will differ

Everything above rests on example inputs: 3.7% funeral inflation, a 4.2% CD, a 22% bracket, 8% stocks, a 10-year horizon and four sample price points. Change any one and the answer can flip. The ones most likely to change your result:

  1. Your actual mortgage or loan rate
  2. Your tax bracket, including state tax
  3. Whether the plan truly guarantees the price
  4. Your state's Medicaid rules
  5. Whether you qualify for VA benefits
  6. Your local funeral home's itemized price list

If this made you think "I need to run this for my situation," you can do that at Zelovari. Enter your price quote, your alternative return and your horizon, and compare all four disposition methods side by side. The math should decide, and you don't have to decide today.
