Built by people who do this every day.

Open tool →Why REME's tools work differently than generic finance calculators
Most "free finance calculator" pages exist to capture SEO traffic and email addresses. REME's tools exist for a different reason: they're the same tools REME's product team uses internally when researching the workflows we automate. Building tools that finance professionals actually use means handling the real edge cases — multi-jurisdiction compliance, current rates that competitors haven't updated, the difference between zero-rated and exempt for VAT, the 75% first/last day rule for per diem. Three principles guide every tool in this hub:
Current rates, verified
Tax authority rates change. IRS mileage went from $0.70 to $0.725 in 2026. India GST 2.0 simplified to 4 rates in September 2025. UK introduced new charity donation VAT relief in April 2026. Our tools update with these changes — typically within weeks, not months. Verify against the source URL we link to.
Multi-jurisdiction by default
Most calculators handle one country. REME's tools handle 6+ countries because real finance teams work across multiple jurisdictions. A team with employees in Singapore, India, UK, and Australia needs tools that handle each country's specifics — not a US-only calculator with international as an afterthought.
No email gate, no watermarks
Every tool here is genuinely free. No "enter your email to download." No watermarks on exports. No upgrade prompts mid-calculation. The tools work in your browser, save state locally, and let you walk away without becoming a marketing contact. We'd rather build trust than capture leads.
Which tool to use when
The 12 tools cover the most common finance-team workflows. Quick-reference for matching tools to specific situations:
The complete expense workflow — and where each tool fits
Individual tools are useful, but expense management is a workflow. Here's how a typical expense submission flows through a finance team — and which tools support each step:
Policy is set
Before any expenses are submitted, the company has an expense policy defining what's reimbursable, approval thresholds, per-jurisdiction rules, and substantiation requirements.
Employee incurs expense
An employee travels, buys office supplies, takes a client to dinner. They get a receipt — paper, digital, or photo. The receipt is the evidence that the transaction happened.
Employee submits the expense
The receipt + supporting context (date, business purpose, client name if entertainment) gets submitted for reimbursement.
Tax calculation happens
Multi-jurisdiction businesses calculate the right VAT/GST/sales tax on each expense — both for company tax filings and for input tax credit recovery.
Mileage and per diem applied
Travel-related expenses get mileage rates and per diem calculated using the right country's rules.
Fraud check happens
Before approval, the submission gets validated — receipt is real, amount matches what's printed, vendor exists, employee submission patterns are normal.
Expense closes in the books
At month-end, all expenses are reconciled, accruals posted, and the period closes. Expense reconciliation is where most finance teams lose 1–3 days.
The same workflow — but automated
REME's product handles all 7 steps automatically: policy enforcement at submission, WhatsApp-based receipt capture, multi-jurisdiction tax classification, mileage/per diem auto-applied, 7-agent AI fraud detection before approval, and continuous reconciliation into your accounting system. The tools in this hub demonstrate the underlying logic — REME's product runs that logic on every submission, in under 200ms, without manual review.
Popular tool combinations
Most teams use 3–4 tools in combination based on their specific workflow. The most common groupings we see:
New finance team setup
First 30 days at a new company. Need to establish baseline policies, templates, and processes.
Distributed team management
Finance team managing employees across multiple countries with different tax and reimbursement rules.
Fraud prevention assessment
CFO or audit team assessing current fraud exposure before implementing prevention controls.
AU/IN-focused operations
Companies primarily operating in Australia and India with significant cross-jurisdiction complexity.
Frequently asked questions
It depends on team size and jurisdictional complexity. Small teams (under 50 employees) typically need: expense report template, expense policy, and one or two tax calculators for their primary jurisdictions. Mid-market teams (50–300 employees) typically need: policy generator, mileage/per diem calculators for travel-heavy roles, multi-jurisdiction tax calculators, and month-end close checklist. Enterprise teams (1,000+) usually have dedicated expense management software but still use specialized calculators for ad-hoc analysis. The 12 tools in this hub cover all three tiers.
Genuinely free. No email gate, no signup, no watermarks on exports, no upgrade prompts mid-calculation. The tools work in your browser with state saved locally. The "catch" if there is one: REME is an expense management product, and we hope you'll consider us when you're evaluating expense management software. But the tools themselves work whether you become a customer or not — we'd rather build trust through useful tools than gate them behind email forms.
We update rates within weeks of authority announcements. Current updates: IRS 2026 mileage rate $0.725/mile (effective January 2026), India GST 2.0 simplified rates 0/5/18/40% (effective September 22, 2025), UK VAT charity donation relief (effective April 1, 2026), HMRC interest rate change (effective April 6, 2026), GSA FY 2026 per diem rates (effective October 1, 2025). Each tool's source links point to the authority URL for verification. If you spot an outdated rate, please report it — we update fast.
Yes. The tools are designed to be useful on their own. Many users come back month after month to use the calculators without ever evaluating REME as a product — that's intentional. REME's product solves a different problem (automating the whole workflow at scale for mid-market companies), but the tools are useful even if you're using Excel + email or a different expense platform.
Six primary countries with native support: United States (IRS rates, GSA per diem, federal compliance), United Kingdom (HMRC rates, VAT, MTD compatibility), Australia (ATO rates, GST, FBT), India (GST 2.0, multi-state), Singapore (IRAS guidelines), United Arab Emirates (Dubai/UAE practice rates). Several tools also include reference data for Canada (CRA mileage), New Zealand (IRD tier rates), and other major business destinations.
Email feedback@reimburseme.ai with bug reports or feature requests. Things we particularly want to know about: outdated tax rates, incorrect calculations, jurisdiction-specific edge cases we missed, accessibility issues. Things we're already working on: additional country support (Vietnam, Indonesia, Philippines, Malaysia rate calculators), additional tool categories (corporate card matching, expense category benchmarks), and integration tools for connecting to popular accounting systems.
