Finance Tools
3 free finance tools. Browser-based. No signup. Privacy-first.
什么是 Finance Tools？
Finance tools are free, browser-based calculators for personal money decisions — compound interest, loan and EMI repayments, and splitting a bill with tip. They run entirely client-side, so the amounts you enter are never uploaded.
What are finance tools?
Make everyday money decisions with confidence: project how savings grow with compound interest, work out a loan’s monthly EMI and total cost, or split a restaurant bill and tip fairly. Each calculator gives a clear breakdown in seconds.
Your figures stay on your device — nothing is sent to a server.
Why client-side?
- Privacy: sensitive data (API keys, payloads, passwords) never leaves your device.
- Speed: no network round-trip — results appear as you type.
- Reliability: works offline once loaded.
- Cost: always free, no signup or rate limits.

常见问题
小费给多少比较合适？
在美国，餐厅堂食服务的常见小费比例是税前金额的15%–20%，其中18%是最常用的默认值。不同国家的小费习惯可能有所不同。
小费是按税前还是税后金额计算的？
本工具根据你输入的账单金额计算小费——如果想按税前金额计算小费，请输入税前的总金额。
这个工具能不能不平均分摊？
本工具只支持平均分摊。如果需要不平均分摊，请先分别计算每个人的餐点费用，再加上对应的小费部分。
每人应付金额会四舍五入吗？
显示的金额精确到分；实际生活中大家通常会把每人应付的金额向上取整。
