- us_aca_subsidy_cliff
Where your 2026 marketplace subsidy sits against the restored 400%-of-poverty cliff — and the clawback risk if income crosses it. For 2026 the enhanced ACA premium tax credits have expired, and the pre-2021 structure is back: below 400% of the federal poverty line your premium…
- us_student_loan_rap_vs_ibr
Your monthly payment and forgiveness timeline under RAP vs IBR — the choice SAVE borrowers are being forced to make. SAVE is dead (vacated, then repealed by the July 2025 law) and the Repayment Assistance Plan (RAP) went live 1 July 2026; PAYE, ICR, and SAVE all end 1 July 2028…
- uk_statutory_redundancy_pay
How much redundancy pay you’re owed — from your age, your years of service and your weekly pay, on the 2026 limits. Redundancy pay in the UK has a formula, and it is stranger than most people expect. Your years of service are weighted by how old you were during each of them — a…
- uk_notice_pay
How many weeks’ notice you’re owed, what it pays, and how much of it is taxed. Your employer owes you notice when they end your job: one week if you have been there under two years, then one week for every full year, up to twelve. This works out your weeks and what they pay…
- netherlands_30_percent_ruling
Whether you qualify for the Dutch 30% ruling, how much of your salary comes tax-free, and what changes when it drops to 27%. Whether the Dutch 30% ruling is worth 30% to you or 27% depends on one thing: the year it was first granted. Granted in 2023 or earlier and it stays at…
- portugal_ifici_nhr_checker
Whether you qualify for Portugal’s IFICI — the activity-gated successor to the NHR regime that closed in 2024. Checks your eligibility for Portugal’s IFICI (Incentivo Fiscal à Investigação Científica e Inovação, widely called "NHR 2.0"): 20% flat tax on eligible-activity…
- thailand_social_security
Your monthly SSO contribution under the 2026 ceiling rise — the ฿15,000 cap stood for 30 years, so the old ฿750 answer is everywhere and wrong. Computes your Thai Social Security Office (SSO) contribution for Section 33 (employees), Section 39 (voluntary ex-employees), or…
- uk_statutory_residence_test
Whether you are UK tax resident this year — the full statutory test, not the 183-day myth. Runs the full UK Statutory Residence Test (FA 2013 Sch 45): automatic overseas tests, automatic UK tests, then the sufficient-ties tables. The 183-day figure everyone (and general AI)…
- us_substantial_presence_test
Whether your US days make you a tax resident — the weighted 3-year formula where 122 days a year is enough, and student-visa days may not count at all. Determines US tax residency under the Substantial Presence Test (IRC §7701(b)): 31+ days this year AND a weighted total ≥ 183…
- ny_statutory_residence_checker
Whether New York can tax you as a resident under the two-prong statutory test — the abode gate people miss, plus the 183-day count where any part of a day counts. For taxpayers NOT domiciled in New York: applies the deterministic statutory-residence test of NY Tax Law…
- uk_stamp_duty_sdlt
What stamp duty you’ll pay on a house in England or Northern Ireland — including first-time buyer relief and the extra on a second home. Stamp duty is not one number attached to a price. Four things can apply at once: the standard bands, first-time buyer relief that takes you to…

Buyer’s, Additional Buyer’s, and Seller’s Stamp Duty at the current IRAS rates — including the 60% foreigner ABSD and the 2025 four-year SSD. Computes Singapore residential stamp duty at the rates actually in force: BSD on the marginal bands up to 6%, ABSD by your exact buyer…
- us_raise_benefits_cliff
What a raise really adds after EITC, CTC, SNAP, Medicaid, and ACA subsidies move against it — the effective marginal rate no single program shows. For working households on any support program, a raise triggers five simultaneous countercurrents: federal tax and FICA go up, EITC…
- income_tax_hong_kong
What your Hong Kong salary actually costs you in tax this year, after allowances — and whether the standard rate caps the bill. Hong Kong does not tax salaries with a bracket table. It runs two calculations and charges you the lower one: progressive rates of 2% to 17% on what…
- hong_kong_profits_tax
Hong Kong profits tax at 8.25%/16.5% for corporations or 7.5%/15% for unincorporated businesses, with the connected-entity election. Hong Kong does not simply charge every company 16.5%. An eligible corporation pays 8.25% on the first HK$2 million of assessable profits and 16.5%…
- income_tax_singapore
YA 2026 Singapore tax for residents, non-resident employees, and non-resident directors — including personal reliefs. Singapore tax depends first on residency. Residents use progressive rates up to 24% after eligible personal reliefs; non-resident employees pay the higher of 15%…
- income_tax_netherlands
2026 Dutch Box 1 salary tax after the general tax credit and employment tax credit — the two amounts generic calculators miss. Dutch headline rates are not the final bill. For employees below AOW age, 2026 Box 1 rates include national insurance, then the algemene heffingskorting…
- china_severance
Statutory severance under China’s Labour Contract Law — the N / N+1 / 2N branch and the 3×-average-wage cap, done right. Computes statutory economic compensation (经济补偿金) on leaving a job in China: the base N (one month per year of service, with the ≥6-month rounding), whether it…

Your exact retirement date under China’s 2025 delayed-retirement reform, plus an estimated monthly pension. Computes your statutory retirement age and date under China’s 2025 progressive delayed-retirement reform (渐进式延迟法定退休年龄) — which staggers the age by birth month, gender, and…

- india_gratuity
Statutory gratuity under the new Labour Codes — the 50% wage floor and the 1-year fixed-term gate that the old answer misses. Computes statutory gratuity under India’s Code on Social Security 2020, in force since 21 Nov 2025 (general AI often still says the Labour Codes are…

- us_freelance_vs_employee
The 1099 rate that truly replaces a W-2 salary — solved from taxes, benefits, and billable reality, not a folk multiplier. Rules of thumb ("charge 1.5× your salary hourly") hide what actually changes when you go independent: you pay both halves of Social Security and Medicare…
- us_self_employment_quarterly_taxes
How much you’ll owe on 2026 freelance income — SE tax, income tax, QBI — and the exact quarterly payment the safe-harbor rules actually require. The first-year freelancer’s tax planner. Computes your 2026 self-employment tax (both halves of Social Security and Medicare…

- compound_growth
What a starting amount plus monthly contributions grows into over time. Projects the future value of a lump sum plus recurring monthly contributions at a given annual return, compounded monthly. Splits the outcome into what you put in versus what compounding earned, and…
- savings_goal
The monthly saving needed to hit a target by a deadline. Given a target amount, what you already have, a time horizon, and an expected return, computes the required monthly contribution — and shows what waiting a year would cost you.
- loan_payment
Monthly payment, total interest, and what paying extra saves. Standard amortized loan math: monthly payment, total cost, interest as a share of principal — plus a concrete extra-payment scenario showing time and interest saved.
- fire_number
The portfolio that makes work optional, and how far away it is. Computes your financial-independence target from annual spending and a safe withdrawal rate, then projects how many years your current savings and monthly contributions take to reach it.
- split_bill
Even split with tip, rounded so nobody argues. Splits a bill evenly across people with an optional tip, and shows the clean rounded amount plus who covers the remainder.
- unit_price
Which package is actually cheaper per unit. Compares two package options by price per unit and quantifies the savings — the supermarket-shelf math, done honestly.
- true_hourly_wage
What a gig actually pays per hour — after vehicle costs, waiting time, and self-employment tax. Turns gross gig or side-hustle earnings into the real hourly wage: counting every hour worked (including waiting and driving between jobs), the full per-mile cost of the vehicle (not…

Your real China take-home month by month — under the cumulative method, where the same salary is taxed more each month as the year goes on. Computes monthly and annual individual income tax (IIT) on a China salary using the actual cumulative withholding method (累计预扣预缴法). Because…
- china_social_insurance
How much 五险一金 comes out of a China salary each month, and what it costs the employer on top. 五险一金 is not a percentage of this month’s pay, which is the assumption almost every calculator makes. Contributions are charged on a contribution base — your average monthly wage across…
- uk_redundancy_package
Redundancy pay, notice and untaken holiday together — and which parts of it the £30,000 exemption does not cover. Being made redundant pays you three different things, taxed three different ways, and the letter usually quotes only the first. Statutory redundancy pay is tax-free…
