What we build
Our calculators help you estimate EMIs, compare prepayment choices, examine rent-versus-buy scenarios, plan a down payment and understand the wider cost of owning a home. They use Indian number formatting and keep every important assumption editable.
How calculations work
The financial engine uses pure TypeScript functions in your browser. Loan schedules carry full numerical precision internally and round only for display. Reducing-balance interest is calculated monthly unless a page explicitly states a different convention.
Calculator pages explain payment timing, compounding, included costs and known limitations. Worked examples use illustrative figures, not advertised market rates.
What we do not claim
HisaabLab is not a bank, broker, lender or registered investment adviser. We do not promise approval, returns, savings or property appreciation. We do not have invented partnerships, professional credentials, testimonials or rankings.
How we plan to sustain the site
The tools are free. The architecture can support clearly labelled display advertising later, but advertising is disabled until an approved publisher account and appropriate privacy and consent setup exist. Calculators will never require an ad click.
Our editorial standard
Regulatory claims link to primary sources where practical. Because financial rules and lender terms change, source dates are documented and launch requires human verification of time-sensitive material.
