How it works
Pay-yourself-first is the reverse budget: an automatic transfer removes your savings the moment income arrives, and every other category adapts to the remainder — reversing the failure mode where saving waits for month-end leftovers that never exist. This calculator sizes that transfer from one decision (a percentage of take-home) and then runs the honesty check most articles skip: whether your actual bills and fun spending fit under the new ceiling. On defaults, 20% of $5,200 moves $1,040 on payday — $12,480 banked yearly at a 20% rate — leaving $4,160 to cover $2,900 of essentials plus $1,100 of fun with $160 to spare. The gap output is deliberately signed: positive slack means the system runs itself; negative squeeze quantifies exactly which lever must move, because skipped transfers are how reverse budgets die quietly in month three. The method's power is psychological architecture rather than math — willpower operates once at payday instead of daily at every checkout, and spending decisions happen inside a smaller, pre-cleared envelope where trade-offs feel real. Start where reality permits: 5–10% proves the machinery works, then raise the percentage with each raise before lifestyle absorbs it. The donut shows the full allocation including slack so nothing hides.
Formula
Transfer = take-home × save-first % | Ceiling = take-home − transfer | Gap = ceiling − (actual essentials + actual fun) | Annual = transfer × 12
Tips
- Automate on payday morning — money seen gets spent; money moved never registers.
- Start at 5–10% if needed; a working small rate beats a failing heroic one.
- Raise the percentage with every raise before lifestyle claims the difference.
- Split the transfer across goals (emergency, investing, debt) but never un-transfer it.
- If squeezed, cut fun first and essentials second — or lower the rate honestly rather than skip.
Frequently asked questions
- What does pay yourself first mean?
- Treating savings as the first bill each month: an automatic transfer removes a fixed share of income before any spending happens. Here, 20% of $5,200 take-home moves $1,040 immediately, leaving $4,160 as the true monthly ceiling everything else must respect.
- What percentage should I pay myself first?
- Twenty percent is a strong target, but sustainability beats heroics: start at 5–10%, prove three consecutive months of automated transfers, then step up two points per quarter. Whatever the number, automation matters more than size — this default's $12,480 yearly comes entirely from one standing instruction.
- How is reverse budgeting different from normal budgeting?
- Direction. Normal budgets allocate forward into categories and hope leftovers become savings; reverse budgeting removes savings upfront and lets remaining categories self-organize under a hard ceiling. It needs no category tracking to succeed — one automated action replaces dozens of monthly decisions.
- Where should my pay-yourself-first money go?
- In priority order: employer retirement match first (instant 50–100% return), high-interest debt second, emergency fund third, then long-term investing. Split one transfer across multiple destinations via standing instructions — the discipline lives in the automation, not the destination choice. Automate every piece so nothing depends on memory.
- What if I can't afford to save anything right now?
- Run the honest numbers here anyway — the gap line shows precisely how large the squeeze is. Then automate something psychologically tiny like $25 per paycheck: the mechanism matters more than the amount initially, because raising an existing automated rate later requires zero ongoing willpower.
