Why it is more than a simple loan calculator
Most people do not struggle with the basic formula. The real problem is understanding what each payment means, how fees change the real cost, whether prepayment actually helps, and how to compare one option with another using the same lens.
Repayment Calculator is built for that second layer. It keeps the schedule, summary, chart, and annualized cost views together so the decision is easier to defend.
Use cases
- Mortgage calculations: commercial mortgage, housing provident fund loan, and combo loan.
- Auto loans: equal principal & interest, balloon/final payment, and additional fee scenarios.
- Consumer and personal credit loans.
- National Student Loan scenarios supported by the current template set.
- Credit card installment and lite revolving calculations.
- Life decisions: home affordability, buy or rent a home, buy or rent a parking space.
Key features
1. Turn contracts into schedules you can actually inspect
Instead of only showing a final payment number, the app surfaces principal, interest, remaining balance, and total cost period by period.
2. Prepayment analysis without hand-waving
Compare full prepayment and partial prepayment paths, shorten-term vs lower-payment options, penalties, and what happens if you continue to prepay later.
3. Look beyond nominal rates
IRR and effective APR help you account for fees, net disbursed amount, and timing, which is often closer to the borrowing cost you actually feel.
4. Automatic LPR defaults with offline fallback
For mortgage scenarios, the app can fetch public LPR defaults while still keeping an offline fallback so the main calculation path does not break.
5. Charts, sharing, and CSV export
Good decisions are easier when the result can be reviewed visually and shared with family, partners, or clients.
6. Housing-related decisions in the same app
Home affordability and buy-or-rent comparisons are included so you can move from pure loan math to a broader living-cost decision without switching tools.
Common questions
Does it support mortgages, housing fund loans, and combo loans?
Yes. Those are part of the main mortgage template set.
Can it estimate prepayment value?
Yes. The app is designed to show how much interest may be saved, how payment paths change, and how the remaining schedule evolves after prepayment.
Why would I care about IRR or effective APR?
Because nominal interest rates alone can hide part of the cost. IRR or effective APR is useful when fees and disbursement structure materially change the real outcome.
Can I use it without network access?
Yes. Core calculations work offline, plans are stored locally, and LPR fetching has an offline fallback.
