80 20 Salary Calculator
Split any salary with the 80/20 budget rule: 80% for spending, 20% for savings. Enter your income monthly or annually and the tool shows both slices, your projected yearly savings, and how the same income splits under the 50/30/20 and 70/20/10 rules. For the most useful split, use your take-home pay rather than gross salary.
Use take-home (after-tax) income for the most useful split. The 80/20 rule is a budgeting guideline, not financial advice.
Quick Answer
With a $5,000 monthly income, the 80/20 rule gives you $4,000 for spending and $1,000 for savings, for a projected $12,000 saved per year. The tool below reproduces these numbers exactly.
Worked example, checked against this exact tool
Monthly income $5,000: the tool reports $4,000 spending (80%) and $1,000 savings (20%), with a projected $12,000 saved per year. The math: $5,000 × 0.80 = $4,000; $5,000 × 0.20 = $1,000; $1,000 × 12 = $12,000. Switch to annual input with $60,000 and the same split appears, with $5,000 per month of spending.
What the 80/20 rule actually says
The 80/20 budget is a simplified form of the 50/30/20 budget: save 20% of your after-tax income first, then spend the other 80% however you like. The 20% covers your emergency fund, retirement accounts, and other savings goals; the 80% covers everything else: housing, food, transport, and fun. It is the simplest budgeting method that works, because there is only one number to track: did the 20% get saved?
Why this page was corrected
An earlier version of this tool labeled the 80% slice “savings” and the 20% slice “expenses”, the exact inverse of the rule its own article described. Every source on the 80/20 budget rule defines it as 20% savings and 80% spending, so the tool now matches the rule: 80% spending first, 20% savings second.
Pay yourself first
The rule only works if the 20% moves before you spend. Set up an automatic transfer on payday into savings or investments: retirement accounts like a 401(k) or TSP savings plan count toward the 20%, and the habit compounds. If 20% is out of reach today, start at whatever you can (even 5%) and raise it as income grows or debts shrink. Many experts treat 15% as the minimum for retirement alone, so 20% total savings is a genuinely strong target.
80/20 vs 50/30/20 vs 70/20/10
All three popular rules agree on saving 20%; they differ on how they split the rest. At $5,000 a month: 80/20 gives $4,000 of unrestricted spending and $1,000 savings; 50/30/20 gives $2,500 needs, $1,500 wants, $1,000 savings; 70/20/10 gives $3,500 living, $1,000 savings, $500 debt payoff or giving. The tool shows all three splits for your income so you can pick the structure that fits. If the comparisons make you want a more detailed plan, a bi-weekly budget or daily savings target can turn the percentages into a schedule.
What competing calculators miss
The best-known rival computes the split but offers no frequency choice and no yearly projection. The best comparison content (80/20 vs 50/30/20 at $5,000/month) lives in an article with no tool attached. This page combines both: monthly or annual input, the yearly savings projection, the three-rule comparison, and the corrected 80%-spending math its predecessor got backwards.
Frequently asked questions
What is the 80/20 rule for salary?+−
Save 20% of your income and spend 80%. On a $5,000 monthly salary that is $4,000 for spending and $1,000 to savings.
Is the 80/20 rule 80% savings or 80% spending?+−
80% spending, 20% savings. The rule is “save 20% first, spend the rest.” Any source showing 80% savings has it backwards.
Should I use gross or take-home pay?+−
Take-home (after-tax) pay. Percentages of gross salary overstate what you can actually spend and save.
How much will I save in a year with the 80/20 rule?+−
Twenty percent of your annual income: 0.20 × annual income. At $5,000 a month that is $12,000 a year.
What counts as the 20% savings?+−
Emergency fund contributions, retirement accounts (401(k), IRA), and other savings or investment goals. Debt payoff above minimums can count too.
What if I cannot save 20%?+−
Start smaller and automate it. Even 5 to 10% on autopilot beats 20% that never happens. Raise the rate when income rises.
How is 80/20 different from 50/30/20?+−
Both save 20%. 50/30/20 subdivides the 80% into 50% needs and 30% wants; 80/20 leaves the whole 80% unrestricted once savings are handled.
Does the 80/20 rule actually work?+−
It works because it is simple enough to follow: one rule, one number to track. Its weakness is that 80% of a low income may not cover basics, in which case saving something smaller still beats saving nothing.
