Start with the full mortgage amortization calculator, then reach for the tools around it: what you can save toward a down payment, whether refinancing is worth the switch, what a foreign-currency figure really costs you, and how a payoff or settlement plays out.
Why these belong next to the mortgage
Before you calculate
01 · Before the loan
Know what you can actually put down
How much you save and how fast changes your down payment, your loan-to-value ratio, and every schedule that follows.
02 · During the loan
Rates move, terms don't have to stay fixed
Refinancing and currency exposure both change the real cost of debt over time — worth checking well after closing, not only at signing.
03 · Closing it out
The last step deserves its own math
Payoffs, settlements, and final balances have their own rules — treating them as an afterthought is where most surprises happen.
Five tools, one panel
Pick a calculator
The mortgage calculator lives right in this suite, with a full payment-by-payment schedule under three amortization systems. The four tools below it each open their own dedicated calculator.
Mortgage Amortization Calculator
The full payment-by-payment schedule
Run the complete amortization schedule under the French, German, or American system, switch between them without losing your inputs, and simulate extra payments to see the effect on interest and term.

Full monthly or annual schedule, exportable as CSV
Model regular contributions against a target amount and timeline, with compounding, to see how long it takes to reach a down payment or reserve fund goal.

Why FinanHelp Built These Financial Tools Around One Mortgage
Most calculator sites give you a single number and stop there. This set of financial tools was built the opposite way: every tool answers a question that comes up at a specific point in the life of the same mortgage, so the numbers you get from one line up with the numbers you get from the next.
How these financial tools fit together
A mortgage isn't one calculation — it's a sequence of decisions that stretches from the first savings deposit to the final payoff. These financial tools are organized around that sequence rather than around isolated formulas, which is why the Mortgage Manager sits at the center of the suite instead of standing alone.
Before you apply: savings and down payment planning
The Savings Calculator models how a monthly contribution, compounded over time, grows into a down payment. Because the same interest-rate logic feeds into the mortgage schedule later, running the numbers here first gives you a realistic loan amount to test in the other financial tools rather than a guess.
During the loan: refinancing and currency exposure
Rates and circumstances change well after closing. The Debt Refinancing Calculator compares your current loan against a new offer, factoring in closing costs, to find the break-even month — while the Currency Converter re-expresses any figure from the suite in a different currency, which matters for remote buyers or income earned abroad.
Closing it out: settlements and payoffs
The Settlement Manager handles the last stretch — a full payoff quote, an early-settlement penalty, or a partial prepayment plan — using the same amortization logic that built the original schedule, so the final numbers stay consistent with everything calculated earlier.
Where to start. If you haven't applied yet, start with the Savings Calculator. If you already have a mortgage, the Mortgage Manager and Debt Refinancing Calculator are the two financial tools worth checking first.
