What does lifestyle creep cost my financial-independence date?
Say how much of each raise goes to spending, and see how much later financial independence arrives, and how your saving rate and balance change over the years.
CREEP MAKES FI LATER BY
4.3years
At these inputs, if 50% of every 2.0% raise goes to spending, financial independence comes in 15.3 years instead of 11.1 if every raise were saved: 4.3 years later. Each dollar of yearly spending you add also raises the FI number by $25. By year 31 you would be spending $105,274 a year instead of $60,000 and saving 48% of pay instead of 70%, with $5,371,957 invested instead of $6,322,420 in today’s dollars.

Your balance against the FI number, with and without creep, in today’s dollars
Every raise savedWith your creepFI number, with creep
The FI number is your yearly spending ÷ 4%. Saving every raise keeps it at $1,500,000; with your creep it climbs to $2,631,849 by year 31, and the balance grows more slowly toward it.
Year by year, with your creep
| Year | After-tax pay | Spending | Saved | Saving rate | Balance |
|---|---|---|---|---|---|
| 1 | $111,600 | $60,000 | $51,600 | 46% | $488,823 |
| 5 | $120,799 | $64,600 | $56,200 | 47% | $803,940 |
| 10 | $133,372 | $70,886 | $62,486 | 47% | $1,301,643 |
| 15 | $147,254 | $77,827 | $69,427 | 47% | $1,940,437 |
| 20 | $162,580 | $85,490 | $77,090 | 47% | $2,753,743 |

| 30 | $198,184 | $103,292 | $94,892 | 48% | $5,076,235 |
| 31 | $202,148 | $105,274 | $96,874 | 48% | $5,371,957 |
Pay rises 2.0% a year above inflation and 50% of the increase is spent, so spending goes from $60,000 to $105,274 and the saving rate from 46% to 48%.

FORMULA
Pay in year t = pay today × (1 + real raise)^(t − 1), after tax and in today’s dollars
Spending in year t = spending today + creep share × (pay in year t − pay today)
Saved in year t = pay − spending, added in twelfths at the end of each month; the balance grows at the real return, (1 + 7%) ÷ (1 + 3%) − 1
Financial independence = the first month the balance reaches that year’s spending ÷ 4%
- Everything is in today’s dollars: the balance grows at the real return of about 3.9% a year (7% less 3% inflation), so the raise is a raise above inflation. Your after-tax pay today is $111,600: $60,000 spent plus $51,600 saved.
- The 2% yearly raise and the 50% creep share are examples you can change. Creep is measured against pay today: a creep share of 50% means half of the total rise in pay since now is spent.
- Financial independence is the point where the balance would fund that year’s spending at a 4% withdrawal rate. Because spending rises with creep, so does the target: each extra dollar of yearly spending adds $25 to it.
- Taxes are inside “after-tax pay”; a raise is treated as an equal rise in after-tax pay. Pay does not stall, and the balance never goes below zero.
- The page does not judge spending. Spending that rises because life costs more, or because you value it, is a choice; the page shows what the choice does to the date.
WORKED EXAMPLE · SAMPLE NUMBERS
Today: $111,600 of after-tax pay, $60,000 of spending, $51,600 saved a year, $420,000 invested; the FI number is $60,000 ÷ 4% = $1,500,000. Year 2: pay $113,832, spending $60,000 + 50% × $2,232 = $61,116, saved $52,716. Year 31: pay $202,148, spending $105,274, saved $96,874, balance $5,371,957 against a target of $2,631,849.

Questions about this result
Spending that rises as your pay does, so a raise never turns into savings. This page lets you say what share of each raise you spend and shows what that does to when you can stop working: a smaller saving each year and a bigger balance needed.
On the example on this page, with pay rising 2% a year above inflation and half of every raise spent, financial independence comes in 15.3 years instead of 11.1 years if every raise were saved, 4.3 years later. If all of each raise is spent it takes 24.8 years, against the 12.5 years it takes with no raises at all.
Because it works twice. Each dollar spent is a dollar not invested, and each dollar of yearly spending you add raises the amount you need to be financially independent by $25, since the target is spending divided by 4%. That is why a bigger raise with half of it spent can leave you no better off than a smaller raise saved.
Look at two points a few years apart. Divide how much your yearly spending rose by how much your after-tax pay rose. If pay rose $10,000 and spending rose $6,000, your creep share is 60%. Use the same after-tax basis for both.
No. Spending more on something that matters to you is a choice, not a mistake. The page only shows the trade: the date, the saving rate and the balance with and without it.
Pay that stops rising, job changes, taxes that rise with income, one-off costs such as a home or children, and the ups and downs of returns. It uses the site’s planning assumptions of a 7% return, 3% inflation and a 4% withdrawal rate.
