How much should I save a month?
The short answer is 20% of take-home pay. The useful answer depends on what is left once your bills are paid. Enter two numbers and get both.
Your essentials are 55% of take-home, above the 50% guideline, so the target above is scaled to what is actually left. That is normal in high-cost areas.
What a savings rate buys you
Every dollar saved does two jobs: it grows your savings and it is a dollar you have learned to live without. Drag the rate to see how long it takes to bank one year of your current spending.
At 10% it takes about nine years to save a year of spending. At 20%, four. At 50%, one. Doubling the rate more than halves the time, because you are saving more and needing less. (Interest ignored to keep the idea clear.)
The 50/30/20 rule, and when to bend it
The 50/30/20 budget comes from Elizabeth Warren and Amelia Warren Tyagi's book All Your Worth. It splits take-home pay into needs (50%), wants (30%) and savings plus extra debt repayment (20%). It is a starting point, not a law:
- High housing costs: needs can easily hit 60–70%. Shrink wants first; keep savings above zero.
- High-interest debt: paying down a card charging 20%+ is often the best "saving" you can do. Keep a small emergency buffer while you do it.
- Irregular income: save a percentage of each payment rather than a fixed amount, and build a larger emergency fund.
Your take-home pay is the starting number here, and it is shaped by how income tax works. Most people assume a raise into a higher bracket shrinks their whole paycheck; ahaboo shows why only the extra dollars get taxed at the higher rate.
Turn the number into a goal
A monthly amount without a destination is easy to skip. Give it a job: first an emergency fund, then named goals with dates in the savings goal tracker. If several goals compete for the same money, split it with sinking funds.
Questions people ask
How much should I save each month?
A widely used starting point is the 50/30/20 rule popularised by Elizabeth Warren: about 50% of take-home pay for needs, 30% for wants and 20% for savings and extra debt payments. If 20% is out of reach, start with any fixed amount and raise it with each pay rise.
Is saving 20% of income realistic?
For many households, not at first — especially with high rent or childcare. The number matters less than consistency. Saving 5% every month beats saving 20% once and giving up.
Should I save a percentage of gross or take-home pay?
The 50/30/20 rule uses take-home (after-tax) pay. Retirement contributions taken from your paycheck before it arrives can count toward the 20%.
How much should I have saved by now?
First an emergency fund of three to six months of essentials, then goals with dates, while contributing to retirement — enough to get any employer match at minimum. The emergency fund calculator sizes the first step.
