Free Career Tools and Calculators

Career tools

These tools answer the questions that come with a job decision: what a change is worth, what leaving costs, and when it actually happens. Each one works on figures you type in.

Resume and ATS

Offers and pay

Leaving and discipline

Why everything here is your number, not a benchmark

None of these calculators contains a salary table, a tax rate, an exchange rate or a benchmark for any role or city. That is a deliberate limit, not a missing feature. A benchmark is only useful if you can check where it came from, and we have not found local pay data we would be willing to cite. Put an invented figure next to your real offer and you get a confident, wrong decision.

What the tools do instead is arithmetic you can verify by hand: annual value against four-year value, vested against unvested, calendar days against working days. The inputs are yours, the formulas are printed on each page, and the numbers are reproducible with a calculator.

Your offer, your salary and your notice period stay in your browser

Three of the four tools run entirely in the page you already loaded. Your salary, your equity and the date you plan to resign are never sent to a server, which means there is nothing to store, nothing to log and nothing to leak.

It also means there is no usage limit. Since a calculation costs us nothing to run, there is no reason to cap it — run the same comparison on ten offers and twenty dates if you like. Only the ATS keyword check is different, because comparing a resume against a posting needs a language model; it runs on our server and is rate limited.

The order people usually use them in

1. Compare the offers while you still have a choice. The offer comparison shows the first year, the ongoing annual value and the total over the period you expect to stay, and it flags the case where those three disagree — a big signing bonus wins year one and loses year four.
2. Price the equity separately. If part of the pay is shares, the equity cliff calculator shows what has vested, what leaving now forfeits, and the exact date the next tranche lands. Before a cliff, that date is usually the most expensive one to resign on.
3. Fix the date only after you have decided. Once you have accepted an offer, the notice period calculator turns your notice period into a last working day — or works backwards from the start date at the new job.
4. Then write it down. The resignation letter templates put that date into a letter that does not invite an argument.

Which one do you need?

• Two offers, different mix of salary, bonus and equity? Use the job offer comparison calculator. Enter both sides on the same currency and compare the three time horizons.
• Shares that vest over four years with a one-year cliff? Use the equity cliff calculator to see the vested amount, the forfeited amount and the next vesting date.
• Resigning, and you need the last working day in writing? Use the notice period calculator, then check the working days involved with the business days calculator.
• Not sure your resume would survive the first filter? Use the free ATS keyword check: paste the resume and the posting, and see the keywords the posting expects that your resume does not contain.

Other tools and guides on this site

Calculators cover the numbers; these pages cover the parts you have to write and say.

• ATS-friendly resume template — a single-column skeleton and the six rules it follows.
• Cover letter template — the four paragraphs worth writing, and the four to cut.
• Resume summary examples — for when the opening two lines are the weak part.
• Thank-you email templates — the follow-up most candidates never send.
• The ATS rejection myth — read this before rewriting your resume because software is "rejecting" it.
• Everyday tools — date, working day, word count and percentage calculators, for everything that is not specifically about a job.

Common questions

Are these career calculators really free?

Yes. There is no account, no email and no checkout anywhere on this site. The calculators run in your browser, which is also why there is no usage limit on them: they cost us nothing to run.

Do you tell me whether an offer is competitive for my market?

No, and that is deliberate. Judging an offer against a market requires reliable local salary data that we have not found a citable source for. Instead these tools take the numbers you already have and work out what they mean over a year, over four years, and on the day you leave.

Which one should I use first?

Start with the offer comparison if you are deciding between two jobs, the equity cliff calculator if part of your pay is shares, and the notice period calculator once you have decided to leave and need your last working day in writing.

Does the ATS check run in the browser like the others?

No. Comparing a resume against a job posting needs a language model, so that one runs on our server and is rate limited per day. Every other tool on this page does its arithmetic locally.

Is any of this legal or financial advice?

No. These tools do arithmetic on the figures you enter. Contract terms, notice rules, tax treatment and equity agreements differ by employer and jurisdiction, and the pages say which part you still need to check with HR or an adviser.
