Compound Interest Table: Growth of $10,000 Over Time
By Talcart · Last updated July 2, 2026
These tables show exactly what a $10,000 lump sum grows to at annual rates from 1% to 12% over 5 to 30 years, computed from A = P(1 + r)^t. They also compare exact doubling times with the Rule of 72 and show how little compounding frequency changes the outcome compared with rate and time.
Growth of $10,000 by interest rate and time
The table below shows what a one-time $10,000 investment grows to with annual compounding (A = P(1 + r)^t) — no further contributions. Read it two ways: down a column to see what a higher rate is worth, and across a row to see what more time is worth. At 8%, the last decade (years 20→30) adds more dollars than the first two decades combined.
| Annual rate | 5 years | 10 years | 15 years | 20 years | 25 years | 30 years |

How long does money take to double?
The exact doubling time is ln(2) ÷ ln(1 + r). The popular Rule of 72 (72 ÷ rate) is a very close approximation in the everyday 4–12% range — the table shows both so you can see how good the shortcut is.
| Annual rate | Exact doubling time | Rule of 72 estimate |
|---|---|---|
| 2% | 35.0 years | 36.0 years |
| 3% | 23.4 years | 24.0 years |
| 4% | 17.7 years | 18.0 years |
| 5% | 14.2 years | 14.4 years |
| 6% | 11.9 years | 12.0 years |
| 7% | 10.2 years | 10.3 years |
| 8% | 9.0 years | 9.0 years |
| 9% | 8.0 years | 8.0 years |
| 10% | 7.3 years | 7.2 years |
| 12% | 6.1 years | 6.0 years |
Does compounding frequency matter?
Less than most people expect. $10,000 for 10 years at a nominal 8% rate grows as follows depending on how often interest is credited — moving all the way from annual to daily compounding adds only about $664 per $10,000 per decade. The rate itself and the time invested matter far more than the frequency.
| Compounding frequency | Value after 10 years (8% nominal) |
|---|---|
| Annually (n = 1) | $21,589 |
| Semi-annually (n = 2) | $21,911 |
| Quarterly (n = 4) | $22,080 |
| Monthly (n = 12) | $22,196 |
| Daily (n = 365) | $22,253 |
Frequently asked questions
It depends on the rate: at 5% compounded annually $10,000 grows to about $26,533 in 20 years; at 8% it reaches about $46,610; at 10% about $67,275. The full table above covers rates from 1% to 12% and horizons from 5 to 30 years.
A = P(1 + r/n)^(n·t), where P is the starting amount, r the annual rate, n the number of compounding periods per year, and t the years invested. The main table uses annual compounding (n = 1); the frequency table shows the effect of larger n.
No — it shows a single lump sum growing untouched, which keeps the comparison across rates clean. To model monthly deposits, use the Compound Interest Calculator or Savings Calculator, which support recurring contributions.
Because interest is earned on previously earned interest. At 8%, $10,000 gains about $4,693 in the first five years but about $32,142 between years 25 and 30 — the same rate applied to a much larger base. This is why starting early matters more than the exact rate.
