Savings Rate Calculator
There is no single definition of a savings rate, which is why comparisons between people are usually comparisons between definitions. This shows three, and lists exactly what went into each.

Why there is no single answer
Ask five people for their savings rate and you will get five definitions. Gross or net income? Does the employer match count? What about paying down a mortgage, or an HSA, or the principal on a car loan?
None of those questions has a correct answer, because a savings rate is not a statutory quantity. What matters is consistency: using the same definition every year so your own numbers are comparable, and knowing which definition someone else used before comparing against them.
This page reports three and lists every component, so the definition is visible rather than assumed.
Gross against net
Saving over gross income is the stricter measure and the one most financial-independence writing means. It is harsh in a useful way: it counts the tax you pay as money not saved, which it is.
Saving over take-home pay is more intuitive and always produces a larger number. Someone saving $30,000 out of $120,000 gross and $88,000 net has a 25% gross rate and a 34% net rate — the same behaviour, two very different-sounding figures.
Neither is wrong. Quoting one without saying which is what causes the confusion.
Does the employer match count?
It is real money going into your retirement account, so excluding it understates what is actually accumulating. It is also not a choice you made or income you could have spent, so including it flatters the number.
The calculator shows both, and the gap between them is often several percentage points. For tracking your own behaviour year to year, the figure excluding it is the more honest one; for projecting a retirement balance, the figure including it is the relevant one.
Debt principal is saving; interest is not
Paying $400 of principal off a loan raises your net worth by $400, exactly as a $400 deposit would. That is the argument for counting it, and it is a good one.
Interest is different. It buys nothing and adds nothing to net worth — it is the cost of having borrowed, and it belongs in spending. This is why the form asks for principal and interest separately, and why only the principal is counted.
Mortgage principal counts on the same logic, with the caveat that the money is illiquid until you sell or borrow against the house. Some people exclude it for that reason; the checkbox lets you do either.
A worked example
$128,000 gross, $92,000 net. Saving $19,000 into a 401(k) with a $5,200 employer match, $6,000 in cash, $9,500 into a brokerage account, $4,300 into an HSA, and $3,600 of debt principal alongside $1,400 of interest.
Your own saving comes to $42,400. Against gross income that is 33.1%; against net income it is 46.1%. Adding the employer match gives $47,600 and a gross rate of 37.2%. Spending is $92,000 less $42,400, or $49,600.
Three defensible figures — 33.1%, 37.2%, and 46.1% — from one year of identical behaviour. That spread is exactly why the calculator refuses to pick one and calls it the answer.
What the number is for
Mainly for comparing your own years against each other. A rate that rises over time means the gap between earning and spending is widening, which is the entire mechanism behind reaching any long-term goal.
It also drives the timeline directly. The FIRE calculator takes savings and spending and turns them into a date, and the rate is the single input that moves that date most.
What this does not cover
- Investment returns. A savings rate measures what you put in, not what it grows to.
- One-off events. A bonus year or a large purchase distorts a single year's figure. A three-year average is more informative.
- Home equity beyond principal. Appreciation raises net worth without being saving.
- Tax on the eventual withdrawal. A dollar in a traditional 401(k) and a dollar in a Roth are not worth the same later.
- Whether the rate is enough. That depends on your target and your horizon, not on a benchmark.

Frequently asked questions
What is a good savings rate?
It depends entirely on your goal and your horizon, which is why this calculator does not offer a benchmark. Someone aiming to retire at 45 needs a very different rate from someone aiming at 67 with a pension.
What is generally true is that the rate matters more than the return, especially in the first decade — and that your own trend over time is more informative than any comparison.
Should I use gross or net income?
Use whichever you will use consistently. Gross is stricter and is what most financial-independence writing means; net is more intuitive and always gives a larger number.
Both are shown here so you can quote either and know which you are quoting.
Does my employer match count towards my savings rate?
It is real money going into your retirement, and it is also not income you chose to save. There is no settled answer.
The calculator reports the rate both ways. For tracking your own behaviour, exclude it; for projecting a balance, include it.
Should mortgage payments count as saving?
The principal portion, yes — it raises net worth exactly as a deposit does. The interest, no; that is the cost of borrowing and belongs in spending.
Your mortgage statement separates them. Enter only the principal.
Does paying off high-interest debt count?
The principal does, on the same logic. And clearing a card at 24% is arguably a better use of a dollar than almost any investment, since the return is guaranteed.
The debt avalanche calculator is the right tool for sequencing that, and this one for measuring it.
How do I improve my savings rate?
It only has two inputs: earn more or spend less. Spending is usually the faster lever because it works on both sides at once — cutting $500 a month raises saving by $6,000 a year and lowers what you eventually need to fund.
Directing raises straight into saving is the version of this that requires no change to how you currently live.
