- What is 3neti/emi-core used for?
- It is a foundational EMI engine for Laravel and PHP applications that calculates equated monthly installments, the interest and principal components of each payment, and complete amortization schedules. Typical uses include lending features, loan calculators, financing flows, and subscription or installment billing. The core is deliberately lightweight and framework-agnostic, so you can use it inside a Laravel app or in plain PHP.
- How do I install 3neti/emi-core with Composer?
- Install it as a normal Composer dependency by running composer require 3neti/emi-core from your project root. Because it is a Laravel-oriented package, its service provider and any configuration are wired up through Laravel package discovery. After installing, clear your cached config with php artisan config:clear so the package settings are picked up correctly.
- Does 3neti/emi-core generate a full amortization schedule?
- Yes, generating complete amortization schedules is one of the package's core features. You supply the loan inputs and receive the full period-by-period breakdown, which you can persist, render in a table, or use to reconcile outstanding balances. This makes it suitable for loan statements and repayment projections, not just a single EMI figure.
- What inputs do I need to calculate an EMI?
- The engine works from three primary inputs: the principal amount, the interest rate, and the tenure of the loan. From those it derives the monthly installment along with the interest component of each period. Keep the units consistent between your rate and tenure, since EMI math is sensitive to whether you pass an annual or monthly rate and a tenure in months or years.
- Is 3neti/emi-core framework-agnostic or Laravel-only?
- The calculation core is framework-agnostic PHP, so the EMI and amortization logic can be reused outside of Laravel entirely. A thin integration layer, including service provider wiring and configuration, is provided for Laravel applications. That split means you can test the math in isolation and still get convenient Laravel access to it.
- Does 3neti/emi-core require a database or Eloquent models?
- No. It is a calculation and domain utility package rather than a persistence layer, so it does not need its own tables or models to compute installments and schedules. If you want to store generated schedules or loan records, you create your own migrations and Eloquent models and feed the package's output into them. This keeps your data model fully under your control.
- Which PHP and Laravel versions does 3neti/emi-core support?
- The exact version constraints are declared in the package's composer.json, so check the require section for the supported PHP and illuminate or laravel framework ranges before upgrading. Because the calculation core is plain PHP, the PHP constraint is usually the more important one to verify for non-Laravel usage. If you are on an older Laravel release, confirm compatibility in the dependency constraints rather than assuming the latest tag will install.
- How do I configure 3neti/emi-core in a Laravel application?
- The package ships Laravel configuration and service provider wiring, so most projects only need Composer installation plus any environment or config values it exposes. Run php artisan vendor:publish to check whether a publishable config file is available in your installed version, then adjust defaults there rather than hard-coding values. After changing config, clear cached configuration so the new values take effect.
- Can 3neti/emi-core handle variable interest rates or prepayments?
- The package is built around straightforward EMI inputs of principal, rate, and tenure, which fits fixed-rate installment and amortization calculations well. More complex scenarios such as floating rates, rate resets, or partial prepayments generally require you to recalculate segments and combine schedules in your own application layer. Verify the behavior you need against the actual API before relying on it for those edge cases.
- How do I test EMI calculations and is the package production-ready?
- Because the calculation core is framework-agnostic and has no database dependency, you can unit test it directly with PHPUnit or Pest by asserting installments, interest components, and schedule totals for known loan examples. Add a few reference cases, such as a standard home or auto loan, and assert that the final closing balance is effectively zero. As with any financial dependency, pin the version in composer.json, review the changelog on upgrades, and validate outputs against your own compliance or accounting requirements before production use.
