Short answer
What percentage of my income should I save?
The largest percentage you can keep up for two years without resenting it. That is a genuinely useful answer rather than an evasion, because a rate you abandon in month five produces nothing at all, and a modest rate that survives a decade produces almost everything.
If you want a starting figure, ten percent of what you take home is a common and defensible place to begin, and twenty percent is a strong position for a household that can reach it. The direction matters more than the number: starting at five and raising it by one point a year beats starting at twenty and quitting.
The percentages, in dollars
Percentages are easy to agree with and hard to feel. On a take home income of 3,000 a month they look like this.
| Rate | Per month | Per year |
|---|---|---|
| 5% | $150 | $1,800 |
| 10% | $300 | $3,600 |
| 15% | $450 | $5,400 |
| 20% | $600 | $7,200 |
Two practical notes about that table. Use take home pay, because a percentage of gross is a percentage of money you never had access to. And count everything going towards the future: the buffer, any extra debt repayment beyond the minimum, and long term investing all belong in the same figure.
Why sustainability beats ambition
The reason the answer is framed around two years rather than around a number is that savings rates fail behaviourally rather than arithmetically. Somebody commits to 25 percent in January, holds it through a tight February and March, hits a real expense in April, misses a month, feels the whole thing has collapsed, and stops.
A rate set at a level that survives an ordinary bad month never triggers that sequence. It also has a compounding advantage of its own: consistency is what allows the arithmetic in compound interest explained to operate, and that arithmetic is unforgiving about gaps.
What five extra points is worth
Ten percent against fifteen percent, over thirty years
- 300 a month at a steady 6 percent $301,355
- 450 a month at the same rate $452,032
- What the extra 150 a month became $150,677
Arithmetic at a flat 6 percent a year compounded monthly, rounded to the nearest dollar. Not a forecast. The extra 150 a month totalled 54,000 in contributions over thirty years and finished at roughly 150,677.
That is the argument for raising the rate slowly rather than for setting it heroically. One percentage point a year, or the whole of any pay rise, moves the figure a long way without ever creating the month that breaks the habit.
Where the money goes first
The percentage question and the destination question get tangled constantly. The rate is how much; the ordering is where it goes, and the ordering used across this site is a sequence rather than a split.
- A small starter buffer, around a thousand, which absorbs ordinary shocks.
- Expensive debt, cleared hard, since a guaranteed cost outranks an uncertain return.
- The buffer completed, to three to six months of essential spending, as set out in how to build an emergency fund.
- Long term investing, alongside any dated goals.
If you do not yet know what your essential monthly spending is, that figure has to come first, because it sizes step three and it also tells you what rate is realistic. That measurement is the subject of how to track your spending.
Related questions
Should the percentage be of gross or take home pay?
Take home, because that is the money you can actually direct. A percentage of gross pay quietly includes deductions you never controlled and makes the figure look better than it is.
Does extra debt repayment count as saving?
For this purpose yes. Paying down an expensive balance improves your position in a guaranteed way, which is more than any investment can promise, and counting it keeps the number honest during the years when debt is the priority.
What if I cannot save anything right now?
Then the useful figure is not a percentage, it is the gap between what comes in and what goes out, and the work is on that gap. A spending record usually finds something, and if it does not, the answer is a genuine one rather than a personal failure.
